I tried the MT Chamber flags in just about every semiauto firearm I own, and while the pros are very apparent (high visible, multi caliber compatibility) there are a few cons that keep my review from glowing as brightly as the flags themselves. The plastic construction is very flexible and somewhat soft. In fact, if you let the slide / bolt close with the full force of the spring, there will start to be chew marks into the back of the flag. While some normal wear and tear won't effect the performance of the flag, I would recommend assisting the bolt or slide close more softly to get the most longevity for your dollar. My only other gripe is that the flags don't have any indication as to their caliber range incorporated into the mold. Instead of having the logo and website on both sides, it would have been nice to have the model number or at least calibers on the flags themselves. Other than that, the MT Chamber flags are a decent evolution of the safety device that many of us overlook.
