I just bought a new 340PD. I shot a little more than a box of .357 ammo the first day. The extraction was very hard. A couple times, the cylinder slid back when I was pressing on the extractor rod. I had to use a squib rod to knock the cases out.
I cleaned it very well with Breakfree CLP, brushes, patches, bore snake, and wiped it dry. I took it out again to check a few things. First, was it just one chamber sticking? Second, would nickel-plated cartridges extract better? For the first 20 rounds of brass cartridges, it extracted fine. Then they started to stick. I marked sticking cylinders with a Sharpie but ended up with at least four marked after 25 rounds. The cylinder was sliding back again and some brass broke inside the cylinder. The nickel-plated cases were sticking also. All of this ammo goes into the 340PD cylinder without any trouble. It drops right in. The same ammo also fires and extracts from a 640 with no issues.
What's going on here?
