This is a Gould & Goodrich B733 USP holster that fits a myriad of guns. I bought this holster in 1996 and have used it a handful of times...it is in perfect brand new condition. I originally purchased this holster to carry my H&K 40 caliber handgun. Last time I pulled the holster out it carried my Glock 22 (40 caliber) perfectly. Just out of curiosity I put my Glock 21SF (45 caliber) in it today and it fit like a dream. I am actually impressed with the number of guns this holster can carry perfectly. If you go to G&G's website there is more info. This holster retails for $57 so get it while you can. I have a Blackhawk that I use now so this one is not getting used. Let me know if you have questions, thanks for looking. $35 TYD!
