Easy build for a beginner.
This was a first time build for me, a little different from the videos I was watching but still not hard at all. Be sure to oil good after assembly, the kit fit my Anderson AM-15 lower no problem. Cycled a few rounds and no problems. Thanks PSA for a new hobby!

She barks a little, but I love her.
I knew going into this build this would be a great little pistol, and I was right. After I pet it on a Spikes lower I had took it to the range and ran 150 rounds or so through it. Not one malfunction. After it was sighted in I was hitting steel at 200 yards.

Palmetto pistol kit Rocks!
For the money you can’t go wrong I never thought a pistol could have such excellent accuracy with iron sights at 100 yards but it delivers good groups and I’m really happy with with it!

Shotty worksmanship and QA on high stress parts.
Everything worked great for the first 200 rounds, then my bolt cam pin snapped around the firing pin. The trigger was sticky as well.
