Several months ago I completely disassembled my brass framed Pietta in order to clean it up and make some cosmetic and other external mods to it. I draw filed the barrel, reshaped the brass grip frame & grips, cut a dovetail for a front sight. No modifications were made to the internal workings of this gun. Just cleaned up and put back together and it had been working flawlessly prior to disassembly.
Upon reassembly, the mainspring seems to have lost a great deal of tension as the hammer cocks & falls very lightly. It will pop a cap, but not consistently. I have adjusted the tension screw in a variety of settings etc. This is not the first time I've torn this gun down & rebuilt it although I've never installed any new parts as it has functioned just fine until now. I find it difficult to believe that the mainspring has become faulty during this period of rebuilding.
What am I missing here?
