for $50 or so you can score a BH CQC Serpa on the bay... thinking about one for my 1911 or my glock, just to try a belt style (as opposed to the paddles that i have). something different. the finger-press-to-release looks like a nice concept too.
i'll probably set fire to my ProTech nylon one, though. it sucks for every gun i have - the thing is just too floppy and covers up far too much of the grip to allow a decent draw.
personally, i don't find the fobus to be difficult to draw from, EXCEPT the one i have for my 1911 Commander which just needs me to pull in the correct way and is more picky about it than the others (but it seems to be a bit more floppy and 'thin' than all the other ones i have, so could have been a bad mfg batch). then again, they're all the adjustable Evolution type, so who knows - maybe the older standard style were difficult overall. also, with a heavy gun like the 1911, the holster is less 'immovable' than with a lighter gun like a Glock, so that might be a factor in longevity. plus, the 1911 has more stuff "sticking out on the side" which seems to wedge itself more than the smooth sides of the Glock.
