I've been buying from them for at least ten years -- maybe closer to twenty. Every once in awhile they'll get me with some piece of Chinese trash but, for the most part, their stuff is decent. They ship promptly if the item is in stock, and I have never had a problem with returns.
And I'm pretty sure Gary Olen, the founder/owner, is a "gun guy." Almost all the holster ads seem to feature one of two 1911s, and I suspect those are his personal pistols.
