I have 2 model 610 revolvers one is a no dash the other is a -3. Both experience hard extraction at times. With the older no dash model being worse. I want to polish the cylinders and was told the best thing to use is a polishing hone from Brownells. But they don't have one for the 10mm/.40. They do make one for the .41 caliber, so I was wondering if I can use that or is there another way to clean up the cylinders?

I'm going to answer my own post because I figured out a way to do it without the brownell hones. And someone else might have the same problem.

Tools needed:
Cleaning jag that will fit your chamber covered with a patch.
Mothers Mag polish
drill

In my case a .44 cal jag with a .22 cal patch worked perfectly.

I coated the patch with the mag polish, centered it on the jag (which is chucked in the drill) put it in the chamber and ran the drill for 1 minute constantly moving the jag from one end of the chamber to the other. After 1 minute remove the patch, install a clean dry one and run it in the chamber for a few seconds.
Repeat process 3 more times. For a total of 4 minutes of polishing per chamber.

The first time I did this I only polished for 1 minute but I still had the hard ejection problems. So hard that I would have to use something to tap on the ejector rod to get the spent cases out. Now, even after shooting a couple of hundred rounds through it the empty cases literally start to fall out when I tip the barrel up to begin a reload.

Be sure to clean the cylinder thoroughly afterwards. The polish gets in every nook and cranny. Also, go slow! I cleaned after every minute of polishing to check the chambers. As soon as the marks were gone I quit.

I haven't had extraction problems, but overpressure or extremely hot rounds will expand the case and make extraction difficult. You could use a stainless borebrush and some polishing compound for cars to polish with a drill. If you shoot both .40 and 10MM, be aware of the carbon ring that forms due to the difference in brass lengths.

That's a neat solution! I shall have to remember that one should I ever have that issue. Btw, that pre-14 I got from ya is a real sweet shooter!

Glad to here it. I was hoping you would keep it in the family

My first thought was high pressure but the cases would stick even with powder puff loads. The polishing took care of it though
