For those around 4" or less, I like the pancake style holsters that kick the butt forward a bit. For the longer ones I like something with a big folded over loop so that when I get in a truck I can have it go along beside my leg and the butt isn't against the seat back.

I have a big box on top of my handgun safe with lots of holsters and just pick one that fits the gun and the occasion. Lots of pawn shops, gun shows and gun shops have a bunch of used holsters to chose from often for less than $20 a piece. I look through them and if L find something decent that fits some of my guns I will get it. The only ones I really went out of my way to get just what I wanted are the ones for my CC guns. Oh, and my 8 3/8" scoped 500 mag

My 1911 rig and my gun belt are from LOBO and they make an excellent hostler and belt.
