So 5 years ago when i was 18, i bought a 1860 army revolver made by Armi San Paolo, i shot it a bunch and then went to college. Last year i opened up the case to find it completely rusted. It looked like it was in a shipwreck for 100 years lol. I soaked it in the strongest rust remover, hit it with steel wool, learned how to cold blue, and now i have it looking brand new once again. The only problem is the hand spring snapped, and Armi San Paolo (now euroarms) doesnt make revolvers anymore. I tried an umberti hand spring, and after shaving off alot of steel with a file to get it to fit, just wasnt going in correctly. I just received a pietta spring, which is much more similar to the original, but the issue is it "pokes out" a few mm too much into the cylinder. It cycles fine until the barrel is attached, and the extra bit of hand pushes the cylinder forward, so that when the barrel is attached it jams. I really dont want to buy another hand spring, so before I mess this one up, should i shave a small ammount off of the hand, or should I snip a small tip off the flat spring. I'm so close to this restoration being complete. Honeslty it was my first gun, and now even though im the proud owner of many "real" guns, this one has a special place in my heart for starting it all with me, and advice would be appreciated.
