I have been doing a lot of reading and seeing lots of differing opinions on slide to frame fit. Some people suggest only stoning and others suggest filing and finishing it with lapping compound. I have looked into the suggested tools being the frame to slide file from brownells and several stoning tools including the everglades ammo and matrix stoning tools. Please let me know what you prefer and what tool you use. Also I don't mind buying the correct tool even if it comes with a higher price. I am a firm believer in the buy once cry once line of thought.
