I just got my Supertuck today and immediately forgot what I was needing to do (move a bed to my ex-wives) and went to try it out. I got my S&W Sigma 9VE and slipped her in. And was thoroughly disappointed.
It moves forwards and backwards in the kydex a quarter of an inch. And if you push from the tang of the pistol you can move the top portion on my pistol at least half an inch. I tried it on and it still moves around ALOT. Tilting the holster at a 45 degree angle dumps my gun right out of the holster.
DEFINITELY not what I was expecting. This is just MY experience and I haven't contacted Crossbreed about this yet so I'm not going to say anything bad.
I'm going to try the suggestion that they include with the holster for better retention. Wet rag and blow dryer time I guess. I'll let you all know how it goes. Emailing Crossbreed in just a few minutes.
