Tisas 1911 Double Stack (2011)

Review

In the world of double stack 1911 style pistols, or 2011’s as some people call them, there are a ton to choose from. Their prices range anywhere from about $500 up to the $5000'nds. Tisas started making their 1911 double stacks a few years ago. These are value priced, 9mm 2011 style pistols that punch above their price range. Tisas has both a carry and full size version. Since I am not carrying a 2011 style pistol, I opted for the Tisas 1911 Duty B9R Double Stack, which is their full size 5” version.

The first thing you notice, when you pull the Tisas 1911 DS out of the box, is all the upgrades it has. To start with, the B9R uses a standard style 2011 polymer grip frame with a rail. This means that it is compatible with most aftermarket grip frames available for 2011 style pistols, including metal frames. This frame has a built-in magazine well and some texture around the grip, as do most of these style frames. Being a 1911 style pistol, there is also a high ride, extended beavertail grip safety with a memory bump. Then there is the slightly extended, ambidextrous, thumb safety. This safety has fine lines on it for better grip. The hammer is a commander-ish style. Then there is an extended magazine release. But somehow, the mag release is not checkered or lined, which I did not care for. All of that is followed by a bull barrel and one piece guide rod. The B9R is also cut for a RMSc footprint optic. So as you can see, this pistol has a ton of upgrades already on it.

Now that we have the base features out of the way, I will get into them a little deeper starting with the slide. The slide on the Tisas B9R resembles any 1911 slide. It has a curved top reminiscent of old school 1911’s. But that is where it stops. Everything else is new school. Tisas put front and rear, angled, cocking serrations on it. These serrations are really nice and grippy so you will have no problems racking the slide. The muzzle end is cut slightly narrower, mainly for looks, because I can’t see any other reason for it. Sitting on top of the slide is a nice set of iron sights. The front is fiber optic and the rear is blackout serrated. The sight picture is nice. Then Tisas cuts the slide for an RMSc style optic. This cut is deep, so much so that the factory iron sights will co-witness with the optic of your choice.

The Tisas’ 2011 style frame is nice. Yes, it has a few minor setbacks, but not everything can be perfect in a $800 2011 ish pistol. The only real setback I found is the smoothness of the grip. The texture Tisas uses is a little lacking. I’m not carrying the B9R next to my skin, so give me some more texture. Even the front and rear checkering needs to be deeper. Tisas does offer a “Coarse” grip module, which I may be checking out. The only other disappointment in the B9R’s frame is the non textured magazine release. Please add some texture. The grip also has a small magazine well built into it. It works well enough, but if you are using the B9R for competition, you may want to add a larger one. Everything else on the grip is great. The Tisas has a rail for lights. Both safeties, the grip and the ambidextrous thumb safety, are nice. The grip safety has a memory bump to help always depress it. The thumb safety has a nice texture and size to it. The B9R also has a squared trigger guard similar to most 2011 style frames.

Since the Tisas B9R is a 1911 style pistol, we have to talk about the trigger. Tisas uses a flat style trigger on the B9R. It appears to be around “medium” length which works well for this pistol. The trigger broke around 5.5 pounds when I first received the B9R. It has a little take up, maybe 0.100 inch maximum. Then it breaks clean with a little bit of over-travel. It is definitely everything a typical 1911 trigger is. After some use, the trigger breaks about 5 pounds now. The trigger is non-adjustable. For a base model 2011 style pistol, the trigger is better than I expected.

The Tisas Duty B9R DS uses industry standard magazines. Any 2011 pattern magazine will work. Anything from the cheaper $25 magazines, up to the elite $100 ones, they all work. The B9R comes with 2 high quality, flush fit, 17 round magazines. I have used a bunch of different magazines, including some 26 round ones. All have run flawlessly in the B9R.

I found the Tisas 1911 DS to be quite accurate. Okay, I didn’t put it in a rest at 25 yards, but I can consistently hit the headbox of a USPSA target at that range. At 7 yards I can get a 1”, 10 shot, round ragged hole. This accuracy has to be from the fact that Tisas uses a bushingless bull barrel in the B9R. They also use a 1 piece guide rod. Of course, the guide rod does make disassembly of the B9R a little more complicated, but nothing terrible. I was pleasantly surprised at how accurate the Tisas was out of the box.

Here are some of my thoughts on the Tisas B9R. It is great for the price point it is at. I got great accuracy from the factory bull barrel. It uses standard 2011 pattern magazines, which all worked flawlessly. I have had zero malfunctions in the 956 rounds I have shot through it. That was using about 7 different brands and weights of 9mm ammunition. Are there things that bother me? Yes. The iron sight cuts use 2 different styles. The rear is a Glock style dovetail, but the front is a Tisas dovetail. So good luck getting aftermarket iron sights that work together. But since I expect that most people will put an optic on it, and it is cut for a Holosun K / RMSc footprint, this doesn’t matter too much. I did like the iron sight picture, it gave me light on both sides of the post as opposed to other sight pictures that basically give you no light on the sides of the post. I ended up mounting an Aimwin PE330 red dot on it. Originally I had one of the Primary Arms Classic series on it, but the PE330 came in and has a larger window. Speaking of optics, I was informed, by a friend, that if you use one of the super large window optics like the Gideon Judge XL, you will need a small riser plate so that the optics window doesn’t hit the top of the slide. SDS Arms has this spacer, but it is not listed on their website. I was impressed with how well the B9R felt while shooting it. It is not as smooth as a $2500 2011. But, after about the first 200 rounds, the slide smoothed up nicely and still has a fairly tight slide to frame fit. Probably my most favorite aspect of the Tisas B9R is that it has aftermarket parts compatibility with most 2011 style pistols. So if you want to upgrade the trigger, or that non-textured mag release, you can.

The Tisas B9R has proved itself to be a fantastic pistol. With all its extras and the way it performs, you can’t go wrong. If you are looking at getting into the double stack 1911 game, I don’t think you can go wrong with the Tisas Duty B9R DS. It performed fantastic for me, with great accuracy and function, all at a great price. Definitely go look at the Tisas firearms and see what you think. They used to be imported by SDS Arms and Tisas’ are made in Turkey, but don’t let that scare you away from a great pistol.

Aimwin PE320

Enclosed Emitter

Red dot Review

In today's market, there are a bunch of good pistol style red dots. They basically come in two categories: open emitter and closed emitter. Aimwin recently released their PE320. The PE320 is an enclosed emitter red dot with a multi-reticle system and a solar fail safe.

As with any quality red dot, the Aimwin PE320 comes with everything needed. In the box you get the optic, a battery, extra screws (including one for the battery tray), wrenches, cleaning cloth, etc. Probably the most important included item is the Acro to RMR adapter. This gives you the ability to mount it on anything that uses the RMR mounting footprint. There are lots of pistol options using a direct RMR footprint.

Mounting the PE320 is pretty straightforward. However, it does come with two options. If you happen to have something with an ACRO mounting footprint, like a riser or a plate adapter, you can mount the PE320 directly to that. If you have a direct mount RMR cut/footprint, you can use the supplied ACRO to RMR adapter. This is what I did. Just screw down the RMR plate onto your slide and then clamp on the PE320. It's really that easy.

Now that the Aimwin PE320 is mounted, you can take it to the range. To initially turn on the PE320, just click the “+” button. The buttons to control the PE320 are located on the left side of the optic. These are rubberized raised buttons labeled “+” and “-”. They are pretty large and easy to use, even if you are wearing gloves. Of course, tapping on a “+” or “-” button will increase or decrease the brightness of the red dot. There are 11 total brightness settings, the 2 lowest are night vision compatible. Now that the PE320 is on, you can sight it in. A nice feature on the Aimwin is its click adjustable windage and elevation screws. Each click adjusts the point of impact 1 MOA, which is fine for these types of red dots. Now that it is sighted in, and you want to completely turn it off, just hold down the “-” button until the dot disappears.

The PE320 uses Aimwin's “aim awake” feature. The “aim awake” is their auto on/off feature. Once you turn on the PE320 this feature is enabled. Aim Awake works like any of the other auto on/off systems. After the optic sits idle for a short time, the dot will turn off. Once you barely move the optic, the dot will turn back on. The aim awake feature helps with battery life, giving the PE320 around 50,000 hours of run time. I am a huge fan of these auto on/off features.

Aimwin's PE320 is not just a red dot. It features a multi-reticle system. So you get the option of either a circle dot, just a circle, or just a red dot. If using one of the options with the circle, the circle also has little hash marks in it that are located every 90 degrees (similar to an Eotech). To cycle through these 3 reticle options, just hold down the “+” button until it changes. The PE320 uses a 36 MOA circle with a 3 MOA dot, or any combination of the three. I like having reticle options and the PE320's are useful for whatever you need or want.

The multi-reticle system of the PE320 is housed inside a large window. How large is the window? 0.94 inches wide by 0.79 inches high. It's a big window, which is really nice for finding the reticle. However, because of its large window, the PE320 is a little wider than a lot of the enclosed ACRO footprint optics. This isn't bad or good, it really just depends on what trade offs you want.

The last notable feature of the PE320 is the solar panel on top of the optics housing. This solar panel adds a “solar failsafe” to the optic. So if your battery is low, and there is enough light, you will still see the reticle. The Solar Failsafe also works when the battery is completely dead, as long as there is enough light. I tried it with the battery out, and the reticle still comes on under normal room lighting. Don't expect it to work in a dark room without a battery. The Solar Failsafe is a nice option to have, especially if you forget to change the battery out once a year. When you do need to change that battery, the PE320 uses a side mount battery tray for easy use.

I mounted the Aimwin PE320 to a Polymer 80 with a Grey Ghost slide. This particular slide is cut to direct mount an RMR footprint. So I ended up using the PE320’s ACRO to RMR plate. I chose this pistol because I use it in various different forms, one of those is using a Recover Tactical 20/80 brace system. This let me try out the PE320 in a chassis style system and as a standard pistol. I put a ton of rounds through it and even beat the crap out of the PE320. No loss of zero and no other problems, even when using the optic as a slide racker off the benches at the range. With the PE320’s adapter plate, the red dot does sit a little higher up on the pistol, but still below the top of the slide. If you want the PE320 to co-witness with iron sights, you will probably have to get some suppressor height ones. Those still might not be tall enough to clear the PE320’s deck height. Speaking of size, the PE320 is large for a pistol style red dot. Not so much height wise, but more width wise. It definitely is wider than a standard Glock slide. I only see this as a problem if you are carrying it inside the waistband. On a rifle, this could be a bonus. Especially since the window size on the PE320 is fantastic. It made finding the dot real easy. I like the 3 MOA dot size, it is a good compromise between speed and accuracy. Since I live in Oregon, it also rains a lot here. Having an enclosed system also makes it way easier to wipe the rain off of the lenses.

If you are in the market for an enclosed style pistol red dot, the Aimwin PE320 might be worth looking at. It has a decently large window and different reticle options. Being larger in size, it would also make a good rifle dot. If you forget to change your battery, it might still work for you thanks to that solar failsafe. It is also durable and held up to my abuse.

Very Nice Enclosed Optic

Just picked this up for my H&K P30L. Had to change the optics plate (Langdon Tactical cut) to an ACRO mount, but it fits perfectly on it and locks down solid. The body appears to be pretty durable and stout without being overly heavy. Controls are nice and large so adjusting brightness and/or choosing dot style is pretty easy. ACRO mounts are probably the easiest installation of any of the footprints since it works like a pic rail. No screws into the plate to worry about getting torqued just right. It does really need a torque spec listed for the clamp screw, though. Never really liked "make it tight, but be careful not to over tighten it" with no spec for what "tight" is. Dots are extremely bright on the max setting and much calmer on the lower settings. Again, it is nice to be able to choose different reticles for different situations. Battery is side loading, which is nice as you don't have to remove the optic for swaps. Only issue I have with the battery compartment is that the tiny screw that holds it in place seems easy to lose as it is not captured. So be careful swapping batteries. We'll see how it does at the range this weekend at holding zero. Adjustments are nice and tactile with just enough resistance to turning to make me think they will stay put pretty good. May wind up being awfully high if you were to use the RMR to ACRO adapter that comes with it on most RMR cut applications. But sits at a nice height on the ACRO specific plate I have installed.
