I just got this holster today, and I have to say I am VERY unhappy with it! I bought this for a glock 17 and it is a terrible fit. They also failed to mention that there is no internal locking device, all it has is a thumb break. I wear an Uncle Mikes holster on my duty belt, and I thought this one would at least have the internal lock, but it does not. I would NOT feel safe wearing this on duty, it would be easy for someone to get out of the holster.
