I'm gonna be sending this thing in for the third time to have the transfer bar replaced, which has snapped again. I really can't figure out why it's happening. When I first got it, I'd been able to put three 50-round boxes of .357 Magnum through it, no problems. Then I started using .38 Special because it was cheaper and I just wanted to plink. Near as I can figure, the .38 Special is the issue. It's of a lower pressure, so I guess it's not expanding quickly enough to catch the chamber walls and stop it from slamming back into the pin, which puts too much stress on the bar for it not to crack over time. The other tell-tale sign pointing to this theory is all the black gunk that rings the bit where the firing pin comes through the frame. Would having the cylinder replaced solve this issue? I figure the chamber walls have gotten "polished" over the years of cleaning, and there's nothing for the low-pressure cases to catch on.
