I know the saying goes something like "shooters shouldn't have thumbs", but seriously. When I shoot my Glock or my 1911, I don't have issues with the weapon cycling and my thumb doesn't catch anything even though it sort of "rests" against the left side of the slide (right handed shooter).
I suspect this is not ideal though. Is the general idea to curl it downward? Or perhaps just flag it out with the whole "flying thumbs" idea. I shot a Beretta 92 the other day and the thumb pressure was causing a FTE about every 2nd round.
Thanks in advance.
