I bought a third issue DS from an online dealer "as is". Cosmetically it's in pretty nice shape. When I got it, it wouldn't carry up. It's 50 years old and hasn't been fired much, so I figured the old lube inside was gummy. I pulled the side plate and cleaned and lubed it as well as I could without further disassembly. Now it usually carried up in DA with an empty cylinder but not completely in SA, and when I took it to the range it wouldn't carry up unless I really yanked on the trigger. I came home, pulled the side plate off, stuck it in some Tupperware, and flooded the insides with Tri-Flow, re-flooding it a couple of times and leaving it for 24 hours. I put it back together and there was no change, but it was cleaner.
Any suggestions for getting this thing running? I'm pretty much resigned to sending it off; if I need to do that, who's a good 'smith for this?
