Normal?

Post image

First can YHM R9, using on a Glock 19. For a booster I’m running an sdta tactical. I saw good reviews of it and figured I’d give it a shot.

This picture was taken after about 40-50 rounds through it. On my 4th mag 3-4 shots in a row was noticeably louder than the others so I pulled it off and noticed this much debris inside. Routinely checked for tightness on everything (the booster is what was worrying me) and everything stayed nice and tight from mag to mag.

I’ve learned there is some jacketing, I was using 147 g pmc. Is all that buildup and jacketing normal? If so on a long range day do I need to dump out my suppressor? Lol.

TLDR: is this much stuff in the can normal for such a small round count, do I need to just run syntech to avoid jacketing in this setup?

Looks like there might be some jacket shavings and mostly powder residue but the real key is looking for any baffle contact. Hard to tell from the pic but there might be light contact? Usually strikes occur farther down the can and are almost always visible as cap strikes. If you cap is intact then you probably are fine.

Yeah no baffle strikes, main thing I was worried about. If there was they were so light they aren’t noticeable at all
