I have for sale a used Smith & Alexander mainspring housing/ magwell, blued, wasn't installed for long but has normal ware marks. Also for sale is a blued Ed Brown memory grip safety (series 80). Safety was never installed but I'm listing it used because of some small surface rust but I have since cleaned it off. Post Office MO preferred payment, Email any questions.
