S&W 19-9 K-Comp

[Sc0]

Has S&W it anyone else performed any upgrades to this model? About 40rds through it and cylinder is pretty much locked up from lead/residue build up where the gas ring is supposed to be around the cylinder and yoke.
146gr HBWC factory .38spl.

Methinks your gun doesn't like
your ammo load. How does
it perform with jacketed self
defense rounds?

I have the same problem with conventionally lubed cast bullets. Load is 13.5gr A2400 and 165 gr CSWCGC 358156. First time, I pulled the cylinder, cleaned, degreased and relubed all revolving parts with Permatex Anti-Seize lube. Next range trip, cylinder started binding at 50 rnds or so.

Cleaned cyl/yoke and loaded some 158gr JHPs with the same powder charge and round count increased significantly before cyl starts to get balky.

I have some coated lead bullets and have been meaning to try them but haven't gotten around to it.

I have a 66-8 that doesn't have the same problem, but have read where others have.

Try some jacketed or coated cast bullets and see what happens.

What kind of 'factory' ammo? I shot some PMC 148 HBWC ammo a while back that was so bad I was getting keyholes at 15 yards after less than 20 rounds. Took hours to scrub the lead out...

I've stuck with .357mag loads so far with my K-comp.
