LONE WOLF FIRING PIN SAFETY 5

Posted by Joe Roque on 20th Apr 2026

Perfect fit and works perfectly
Excellent part 5

Posted by Aaron on 5th May 2025

I used one of these to fix issues in a friend's build, he used some no name parts kit on sale from some no name distributor. My only criticism would be the somewhat sharp transition from the round portion to the flat. That shoulder makes for a tactile "bump" in the trigger pull. Otherwise it's a solid part the works every bit as good as a factory part.
Solid piece with an easy install 5

Nice product. Combined this with the 3.5lb connector and it smoothed out the trigger pull on my Glock 40 nicely.
Far better than the LoneWolf plated version 5

worth the little extra over the stock Glock because smoother take-up, and far better than the plated LoneWolf! (plating flakes off and fouls Plunger and Stiker channels
