Use the race master here. I have no issue holster in the gun at all. It took me a little bit to get use to holstering it due to being new to the race holsters but the lock is solid. If you plan on using it for one type gun use the racer and save some bucks. I went racaster as my primary is an sti with a backup glock. So one holster does both with a couple min and 40 dollar block swap
