DEFINITELY - but is it TOO "much?"

BRAND NEW TRP Operator slide, mated to a(n upgraded - & cerakoted) mil-spec frame. It was WAAAY too tight, first time at the range. Wouldn't cycle, and every shot FTE (10rds. was enough that day!).


My 'smitty lapped the slide a bit, and although it's still tight, the gun fires and cycles perfectly, BUT...

Noticed the top of bbl was rubbing the inside of the slide a bit. I took several shots, from slightly different angles/flash, so hopefully they've done it some justice.


Area in question in particular, is to the right/below the "o" in "Auto"









My fingers are old and calloused, but I can't perceptively FEEL any 'roughness' to that area, which of course, means nothing.

What dost the brain trust think? Normal? Acceptable, Troublesome? Or...???

Put 200 rds. of Blazer aluminum through it, for reference. NO FTF's or FTE's, for reference.
