I have an old revovler I bought at a gun show not too long ago. I knew when I baught the thing that it would work but it'd need some tuning and elbow-grease involved to get it to work decently. *takes a deep breath* Its an Rohm Gmrh Sontheim / Brenz. Its the Model 57 in 44 magnum. I feel dirty for telling you guys I actually paid for the thing because I know how most people view the RG revolvers and most of them have good reason to hate them. Here's my problems: 1. When I actually used the gun I was getting soft primer hits when I would pull the trigger with just enough force to release the hammer in DA the thing would fire sometimes and sometimes it wouldn't. When it wouldnt the primers had been hit but not enough to make them go off. In SA mode the gun barely ever fired and always gave soft primer hits. 2. When I took the gun apart to fix the problem I undid the firing pin bushing and the firing pin spring when flying into the oblivion. First of all, I have to find replacement parts, Bob's Gun Shop has parts for a RG-57 but its listed as a 357 Magnum. Do you think the springs would match up to my 44 magnum's springs? The other route I could take is getting springs for a different model like a 38 special of the same type build, I guess they'd be the same as the 357 mag springs but with better availability from Numrich's website. The final thing is to just get a new firing pin spring to replace the one I lost and see if I can make the current springs work somehow. I figured I'd replace all the springs in the gun with new ones to see if this fixes the problem with soft primer hits. The trigger spring, firing pin spring, mainspring. I figure if this doesnt fix the problem I would compress the mainspring somehow, thereby making the hammer have more force on the firing pin when fired. Do you think this will work? I'm merely trying to work again, it was fun to shoot before I lost the firing pin spring and I didnt have any safety issues with it. Just need a little advice on the situation.
