Got my knoxx spec ops this morning and put it on. I didnt expect it to be so heavy it sure adds alot of weight to the grizzly. Thats ok though. My only complaints are that the slide release is pretty much unreachable with my hand on the pistol grip. The safety isnt easy either. I'm used to the valtro which was designed for a pistol grip so everything is easy to reach. Its a good sturdy unit though and deffinetly shortens the overall length of the gun a bit which is what I was most interested in.
