I thought I would share what was posted to the Facebook Form 1 group with a JK yesterday. I don’t know the details at all, and the post didn’t have much except he ran 8 mags and they were not dumps.
I was thinking about one of these for 9mm, but I’m going to sit back and see if he develops one with different material. I don’t find this overly impressive, and for the money charging, I’m thinking that other materials will push his up past form 4 range.
Might just stick with quietbore.
