My thumb wasn’t “over” the slide. It wrapped around the left side of the grip as normal. Kinda hard to explain but the knuckle I am referring to is the one closest to the wrist where the thumb meets the hand(slide would skin it on top). Got small hands (among other things) and I attribute it to that. Don’t have that problem with any other semi I’ve ever fired, and I’ve fired my share of others........ Hope that made sense.
That’s why the new Smith and Wesson PPKs have a larger “beavertail” on the back of the grip, to protect us ham fisted Americans (some of us anyway) from the slide.
I don’t know much about Makarov’s, but I do enjoy my PPK.
Ah, so on your griping hand. Sorry to get on to you. I see people a lot putting the thumb on their supporting hand right over the back of the gripping hand, straight across the path of the slide. Sometimes they are lucky and the slide goes right over without hitting and rare the unlucky ones get stitches.
