He acknowledges that the first rifle was sluggish to cycle and likely had a defect in the buffer tube causing drag. This prevented the rifle from going fully into battery. While this is certainly plausible, it doesnāt explain why the rifle was able to ignite the primer while OOB. His point about blowback firearms being notorious for OOB discharge is true, but whether thatās an inherent design issue or something particular to the S&W response remains unclear. Since this rifle is a hideous piece of plastic in a crowded 9mm pcc market, it Is of no real significance to me although Iām sure many folks will buy it.
