My mag catch stop for my P226 Mk25 got away from me and sproinged across the room. Since it’s so tiny, I was shocked when I found it and decided to order a few to have on hand…only nobody had any. Nobode except Matrix Precision. So I ordered four and installed one when they arrived just to make sure, and it’s a perfect fit. I highly recommend ordering a few and keeping in the parts drawer because they are easy to lose and hard to find.
