One stovepipe and one FTE within the first 200. 'pipe was with WWB, FTE was with Lawman. I also shot some Speer Gold Dot carry ammo to make sure it works, it does and seems a bit hotter than the usual target ammo.
I've examined the ejected brass and there are no markings of a bad extractor or firing pin issues.
Only other problem is that the plastic pins start to walk out of the frame and need to be punched back into place.
I doubt that Ruger actually intended anyone to shoot the damn thing on a regular basis.
I keep mine pretty greasy with TW-25b on the rails.
