I have a Comp Tac CTAC holster for G20/G21. I used it probably 10 times but I ended up selling my 20 and 21 after I decided the large frames just weren't for me (As much as I really like them). CTAC is my favorite holster and I have a couple for my smaller frame glocks. I'm looking to trade this one for either a CTAC SLIDE version for 9/40/357 glocks, or possibly for a 17/22/31 model, but preferably the slide version.
Mine has the 1.75 standard clips. Also wanted to note that due to it having been stored with one of the leather flaps folded over slightly, that flap is no longer as stiff like the other side (Its more "Bendy"
). I really do not believe that it affects function at all, but just wanted to mention upfront.
