Lone wolf makes some good parts, but they are not in this kit. - Lone Wolf Arms Glock Slide Completion Kit

I combined this slide kit with a Lone Wolf frame kit, which included a Lone Wolf adjustable trigger housing assembly.
The back plate included here would not clear the Lone Wolf Trigger housing! It wouldn't even work with its own part! I had to cut and file the back plate to clear the housing and cycle.
Almost as bad, the back plate was smooth (instead of being serrated) so you can't get it off without inserting a screwdriver into the gap.

The rest of the parts are cheaply made, the plastic parts feel stiff and brittle, the firing pin would stick in the Alpha Marksman V4 slide aperture and needed to be honed down so it would cycle. I think if I'd tried to shoot the gun at that point it would have gone uncontrollably full-auto.
I think I wound up using the extractor and then just bagged up the rest of the parts to maybe use in an emergency.
Pass on this kit.
