I just got a 22/45 and shot it a couple times then decided to replace the sear and hammer with replacements from Volquartson. Well I re-assembeled it wrong and now it won't fire and it won't disassemble. Specifically now when I try and remove the mainspring housing, it only moves a quarter inch or so and won't remove any further. I will take what abuse anyone might want to heap on me, but I need to get this fixed. Does anyone know what gunsmith locally to take it to get it fixed? Alternately is there someone that has messed these things up enough to be able to help?
