Remove them, plug the hole, fixed. Sort of...

I've plugged all of mine. My 342PD locked up on me once and the 329PD looked like a likely candidate for it. Since the 342 is my EDC, I didn't want to risk a recurrence at the wrong time. The others I did to eliminate a non-improvement and a reminder of political encroachment on liberty. This matters to some. I didn't want a "Hillary hole". Yecch! But I guess that outcome was pretty obviously in the cards with the purchase of S&W by Saf-T-Hammer.

I have never had a firearms performance issue with any of the newer guns unrelated to the lock, and I've got some both way, but I have a marked dis-preference for the saf-t-holy ones.
