M48 Back from S&W

[KJACK]

My 48 had developed an annoying jamming of the cylinder after a few hand cycles (NEVER letting the hammer fall - I eased it down). Cylinder would just not move.

I broke down and sent it to Springfield. After 2 weeks (and a few annoying days trying to get it back from UPS -don't get me started!) I got it back and it cycles fine.

The repair sheet called it "cramping", with the fix that the gun was cleaned.

Now I thought I do a pretty thorough job of cleaning my firearms (after 50 years as an owner), but obviously not.

What method do you think was used to get it any cleaner than I do - sonic cleaner? dunk tank?

I dont know maybe they did dunk it in a sonic bath but I bet these guys see every thing imagineable every day and yours was not the first they had dealt with. I sent a 657 back that would not double-action fire if the barrel was elevated, I dont know what they did but it has worked for 20 years, They just have a way with their product.

After soaking in #9 overnight(dissembled of course) slip the yoke back into the cylinder and spin, pull apart and clean the yoke tube again. Repeat about four times and you'll be ready to dry, lube, and reassemble. That should do it.
