I usually shoot a 155 gr. jhpt @ about 1400, don't remember the exact load, but it's using Vhit. N350 & new Starline brass, Win. std. primers. Same load makes about 1475 from my G20.
I've been using a Galco Concealable holster since 1997, actually have 2 of them, like good boots, it just doesn't do to get it sweaty & not give it a chance to dry out.
So comfortable that it's now my CCW holster.
