Can I vote for myself?!?
But really, there are a lot of good holsters out there, and a lot of really crappy ones too. The topic is pretty broad to boot... Tactical holsters, duty holsters, concealment holsters, "range holsters", the list goes on and on. Ask 10 guys their favorite holster (and/ or maker) and I bet you get at least 8 different answers. Small-time guys and companies like me are popping up all over the place, so it's pretty easy to get affordable custom gear these days. And now in all seriousness, you can add me to your list
(see signature if you're interested).
Here is an ever growing, comprehensive list of holster makers from another website:
