Ok, my first detail strip on a S&W 1911. When I finished, well past my normal bedtime, the thing would be in autofire. I held the trigger and recocked and the hammer would drop right back. What did I miss? It must be something fairly simple. Also, what's the right way to reinstall the hammer, do you try and force it in against the main spring? That seemed impossible. I left the main spring housing part way out and then pushed it in against the spring pressure and put in the mainspring housing. Is that right? Appreciate any help or I'm off to a gunsmith Monday.
