If you're gonna keep HD guns loaded, do you have to put in less than full capacity to keep the springs functioning? I heard something about GIs in Vietnam keeping their mags 3/4 empty because the last rounds would be too far below the mag lips by the time they got to them. Any of you load your guns part-way like that? Of course it's no problem with revolvers, SxS, and helical mags, but what do you all recommend for the more common guns? Do any good HD/SD guns have this problem worked out?
