Mine with about 1000 fed automatch, cci minimags, prime brand 22. It had the yoke and something else replaced by the factory immediately. Cylinder would lock up.
Runs a lot better now. Though the prime brand .22s tend to stick in the cylinder. Need to clean the lead off better with a pick.
Makes me wonder how big the throats are on these things. On .38 and .357 J frames I've measured, the throats are .359. That leads to severe and surprisingly rapid leading when shooting .357 sized lead, even when it's a mild load like wadcutters. These .22LRs, firing soft swaged bullets, may be exhibiting the same phenomenon. Wouldn't surprise me to see .224-.225 throats.

Not another dime.
I have a Scandium 317 that has had many thousands of .22 rounds through it. Not sure the last time I cleaned it, but it has always run perfectly. It is a pre lock production model.
Likes pretty much everything in every caliber.
I also have a 317 that is at about the 1k mark and doesn’t look anywhere near that rough.

If that were in stock I would consider buying one and opening the throat a bit.
Stupid thing locked up on 1/10 cylinders of Minimags yesterday and they are near impossible to extract. I hit is with a drill chucked brass brush with chore boy surrounding it. I hope that helps. I don’t want to get too abrasive with the aluminum cylinder.
I sent it back to S&W and they turned it around in a month. Gunsmith notes: Repaired Yoke, Repaired Bolt, replaced extractor.
Indeed the extractor looks decent now:
I ran 80 Minimags and 8 Velocitors. No locking cylinder. No extreme
difficulty ejecting. No spitting lead. I think it is fixed!
One dud round that fired second strike. The Velocitors were fired last
and extracted better than the Minimags.
It remains fun to shoot and extremely accurate with the Lasergrips. I didn’t even have to re zero them after taking them on and off. Surprised myself with this 97-3x at 25 yards. Not bad for a barrel with 3,000 on it.
