I went from a Glock 42 to my CCP M2 with no major issues. It is much more accurate than the G42, the sights on the Glock are notoriously not the best. But, I’ll be changing out the CCP sights to trijicon sights soon to make it even better. The only ammo it has had problems with is some cheap stuff my husband got for me...otherwise it eats everything I put through it. It’s easy to carry in my Vedder kydex holster...even with a skirt, I usually forget I’m carrying it. I have arthritis in both hands, but it’s worse in my left...and I have to say, the CCP is great for someone like me. It fits my hand(s) to a T. I have no trouble cleaning it either. The trigger gets better every time I shoot it, either in dry fire practice or taking it to the range.
