Definite Improvement over OEM Part 7/27/2020
I ordered the Extended Slide Release for my WCP320 and was concerned it would protrude too much. It works perfectly and is an improvement over the stock SIG part. It would be especially beneficial for the SIG OEM Grip Modules.
Actually useful 7/18/2020
Before purchasing this, the slide stop on my P320 was just for aesthetics. I was unable to operate it without fumbling with the gun. After installing, I could immediately tell the difference in operation. It brought the slide stop out of the way of my thumb, so no more rubbing. Secondly and more importantly, I could operate the slide stop with ease. After running a few reload drills, I could tell the time difference in function. This simply part made a huge impact on functionality of my P320.
