Check your crimp on your reloads. Yeah but even with that gold dot it’s not a good group. Just a better than the worst. Link to comment Share on other sites More sharing options...

SufferInSilence Posted October 5, 2023 Author Share Posted October 5, 2023 Yeah I’m going to put my 38SC barrel in and see how that groups. Then see fro there. Link to comment Share on other sites More sharing options...
SufferInSilence Posted October 8, 2023 Author Share Posted October 8, 2023 **Anyone recognize this logo/brand?** I’m trying to track down a replacement for this cone barrel. It’s measuring about 4.75 (4 3/4”) from what I can tell. Just don’t know who made or still sticks them. Going test my 38SC barrel tomorrow to see if maybe my 9mm barrel is just shot out. I can say though, the 38SC barrel is much tighter in the slide when I assemble the gun and grab the comp and shake/twist it, there’s little to no play. There’s play in the 9mm barrel when doing this.

SufferInSilence Posted October 9, 2023 Author Share Posted October 9, 2023 Never mind. It’s a Storm Lake barrel. Still, can’t find the right replacement though. Link to comment Share on other sites More sharing options...
shred Posted October 9, 2023 Share Posted October 9, 2023 Nobody makes cone comp barrels as-such anymore to my knowledge- they're made from regular (or turned-down bull) barrels lathe-threaded and cut off to match the cone comp. Sure looks like how that one was made, so if you want a new barrel, get a new barrel with the same or larger OD, thread for cone, cut off and crown muzzle as needed and screw on cone. Green sleeve retainer loctite usually glues it all together so if you want that old cone off for re-use and to measure the old threads, heat the cone with a propane torch while wrenching on it hot. Use a padded wrench or vise if you want to reuse the comp. This kind of thing was pretty standard open gun gunsmithing back in the day so there should be somebody around that does it if you don't want to bust out with a lathe. For a switch-barrel gun you might need to turn a skosh off the cone end of the comp to get it timed right with the slide muzzle end. Link to comment Share on other sites More sharing options...
SufferInSilence Posted October 17, 2023 Author Share Posted October 17, 2023 (edited) *UPDATE* -Soaked the comp in 50-50 peroxide/vinegar. -Scraped “everything” out. -9mm reamed the bore of the comp. This tightened up the terrible left/right spread but with each shot, the group climbed up. This happened “every time” and was worse the hotter the barrel got. Threw in the 38SC barrel to rule out any frame, slide, mount, dot issues. 38SC ran fine so, it seems the 9mm barrel is just clapped out.

jim vaughan Posted October 18, 2023 Share Posted October 18, 2023 Or the diameter of your bullets is not suitable for that 9mm barrel. Link to comment Share on other sites More sharing options...
SufferInSilence Posted October 18, 2023 Author Share Posted October 18, 2023 @jim vaughan I sent it off for a new barrel/comp so, I’ll have an update whoever that happens. Sounds expensive though. Link to comment Share on other sites More sharing options...
