I installed mine (G43) about 250 rounds ago. No issues of any kind with it.
When Glock releases a factory extended slide stop and mags for the 43, I will ditch my Vickers and Pearce parts. But it looks like that ain't gonna happen.Is your OEM slide stop not working?
Okay, I know it works. But that deep, visceral compulsion to d*ck up your Glock is right up there with the desire to breath, eat and reproduce. Its in the DNA.
