Works great! - Shield Arms Glock 43X/48 Gen 1/2 Aluminum Premium Magwell

Product works great. Forces you to use the best grip position possible on such a small frame pistol. Doesn’t print too terribly during CCW, however, that also depends upon your caloric retention problems. Installation was a snap. However, as a previous reviewer noted, the two-piece design is not optimal (hence 4 stars). Be sure not to over tighten the retention screw, which in order to get it flush with the magwell, it comes dangerously close to stripping the threads.
