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.
