Only store that sells a particular holster. Unfortunately I did not try it on one of their similar firearms before purchasing, and the fellow at the counter said I was good, but it was too small. Being from out of state, that is a bit of a challenge to return. Fortunately the manufacturer said they will exchange, but I had hoped to avoid shipping. While my experience was so so, I'd give it a chance if I lived in the area. Some of the firearms felt overpriced a tad. If you are a veteran, ask for a veterans discount. Don't know if it just applies to accessories or firearms also.
