Pierce grip ext.

[Ol'coot]

I have them on all of my 6 round mags for my PM9 they make a huge difference in my grip of the gun as it gives my pinkie a place to rest. No issuse with reliablity in any way and I cannot tell any difference in concealment using a crossbreed mini-tuck. Great addition IMHO

I have one mag with it on and use it on both my PM9 and MK9. Good for cargo style pockets and range shooting. Shows a little too much for owb unless you wear a heavy type of sweater or sweatshirt. I plan to get a couple more mags and put the other extension on one of them. It really is a case of what works for you and not what works for me I guess.

I tried the grip extensions on my MK9 and had all sorts of magazine issues leading to feeding and jams. I took them off and the gun returned to 100% reliability. Never had problems with the 7-round extended magazines, just with the Pierce grip extensions.

Same thing happened to me, I guess i must have been putting too much pressure on the pinkie extension. Took it back off and never had another problem.
