Found a old 581 missing the magazine and sights today being sold as a part gun for $50 even. Got home and stuck a magazine in it and to my suprise it snapped in and out properly. Gonna try a snap cap in the morning and if the firing pin strikes properly I'm going to test safety and clean it for live fire. Can't hardly use iron sights so a 4 power scope might bring this old warrior back to life. Updates to come!
