Trying to determine whats best for my Glock 23/Gen4 in terms of comfortable positions, concealment, ease of taking it off, safety and such. I normally don't wear a belt, but looks like I'll start having to do so. Also I wear all shirts outside my pants. I want to get a good one, but don't want to drop 50-100 bucks on something that I don't like and many of my friends don't carry, so I cannot "test" theirs. What works for you, what do you like/dislike about a particular holster that you have tried/used?
