Sparks from my SR9?
I was using some cheap ammo and hadn't cleaned in maybe 150 rounds or so. I obviously wasn't focusing on the end of the barrel, but on some shots I noticed there were straight sparks flying out, rather than a "flame cloud". It was random and during the same magazine it would go back and forth between sparks and flames.
Is this bad? I normally use winchester white box but decided to see how the SR9 would handle the really cheap stuff. It performed flawlessly. The trigger pull is settling and I have it sighted in perfectly now. What a great gun!
