Great serpa substitute - BlackHawk Standard CQD Holster

I normally use a BlackHawk SERPA holster for a Springfield XDM 9MM 4.5" w/ Vortex Venom when I take defensive pistol courses, but, given that some facilities ban the use of the SERPA holster, this holster makes a great alternative. The retention is easily adjustable and holds the firearm well enough to keep it from popping out while doing some light running around; I've combined mine with the BlackHawk drop-leg platform and it makes for a great package. My only complaint is that this is the longest model that I could find and it's designed for the 4" model. Luckily, the holster has an open bottom, so fitting the 4.5" model in is no problem, the end of the firearm just sticks out a little. If you're looking for an inexpensive holster and the SERPA has caught your eye, but you're worried about the locking mechanism being a problem, this holster makes a great substitute.
