I love my MkIII, the mag release is in a logical place, instead of the heel release, the LCI came out reasonable easy, I didn't bother to cover the hole, no reason I could think of to do that. The mag safety had to go of course, and a few other things I did which I don't recall exactly what they were. It's a very accurate weapon, and with the speed loader is capable of going through many boxes of 22. LR in an hour or so.
