Re: Should we go back to the 1911?
Thats why I like some active retention on the holster. First time Top saw me prancing about with that serpa holster on my thigh, he jumped me an tried to snatch my pistol; couldn't figure out the button. So we drilled 'retention ready' with drawn wpn, and retention w/ holstered wpn. If the wpn is suitably locked in the holster, you have both arms free for scrapping. Inevitably, you wind up in a gaggle of those happy, friendly people who are milling around and messing with your desire to keep your firing-side hip away from them. With the right holster, you don't have to worry about providing one of them a wpn. Let those two bruisers you posted as security pull you out.
Long ago I switched to left-handedness with hand guns. I'm right-eyed and use long guns on the right side. Transitioning from primary to secondary armament is like a sweet, incense filled dream. Cut the pie R or L from a strong side, etc.
I think they ought to go with a plastic holster, something you can quickly shove your drive-on rag through and its clean and dry...spent a lot of time with my little friend rusting away in soggy nylon or leather; one, well engineered condition of retention; maybe a removable flap(although fitted holsters do well at excluding crap from all but the grips/hammer area); and separate holsters for R or L hand firers. I mean they have berets in how many colors and sizes?
