I admit that holsters perplex me.
Personally I've just about concluded that holsters are an even more personal choice than firearms, that is, I think it's easier for someone to choose the gun they want then the holster they want to carry it in.
I base this ONLY on a few folk I know who have bought a lot of different holsters for a couple of guns that they want to carry.
I've bought cheap holsters that have been terrible thinking that the holster is 'not that big a deal' so I wasted money and learned from that that I should buy from a 'quality' company.
But still a 'good quality' holster might not turn out good for me.
What to do? Best is if you can try 'em on with your gun and see how they fit but that's not too practical. I like the companies that show pictures of the holsters in use on a human model but that is no substitute for trying them on yourself.
I guess what I'm saying is holsters can be a real black hole in your shooting budget and I've got no real solution for you just a saying that if you go with the higher end 'quality' goods you'll at least avoid half the problems I've had.
