Shot it some. Pick your mags carefully. Reviews all say “Go with ABC not XYZ” and my experience is they are correct. The higher recommended magazines (28 and 30 round) worked well for me while the lower rated company’s magazines failed.
Do you have a can for it?
Lighting off a few rounds at the range rattled some teeth/ears/heads of bystanders. When I put on a .30 cal can they all relaxed a bit and commented that it made a big difference.
Other than that, what can I tell you? It’s PSA. It will probably work but it isn’t top shelf. (But then again it isn’t top shelf price, either.) If it doesn’t work they say they will fix it.
