This is the manufacturer's most highly recommended ammunition for the Advantage Arms .22 conversion for Glock 19's.
I compared these to some 2017 MiniMags and aside from the box labels the rounds themselves look identical.
I was surprised that the five, one-hundred round boxes were just falling around loose inside the shipping box with a ridiculous sheet of expanded cardboard, which probably did nothing to protect the plastic boxes.
The CCI MiniMags' 100-round boxes were wrapped in a clingy cellophane, however; and miraculously all survived shipping across the country. Shipping was fast.

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.

The Poly80 9mm Glock frame does not fit all 9mm Glock holsters; this DeSantis works with no modifications needed. Good professional-level gear. No retention devices so it's best suited for concealed carry or range use, IMO. Holds its shape and should last about forever.
