In IDPA, the last few matches in which I have done a slide lock reload, when I slam the mag home, the slide release moves enough to allow the slide to close. I know this can shave some time, but it is rather disconcerting. Am I being overly aggressive when putting the magazine in? I know that I am pushing it in with a good deal of force, and then slamming my hand on the base plate. Should I try a "less aggressive" magazine insert? When I practice at home with snap caps and less than full capacity magazines I cannot duplicate this. Is this just a case of match adrenaline? Thanks.
