The gun I have owned the longest would be my Remington 550-1 .22rf that I got for Christmas from my folks when I was 17. The handgun I bought and have owned the longest is a Colt Frontier Six Shooter 44-40 made in 1884, I rebarreled it, added a .44Spl cylinder, replaced internal parts and ejector housing and cold blued it. This may sound like a real screw up but not in the 1970s, I followed the example of Skeeter Skelton and made what the factory didn't. If I could afford to do it again I wouldn't only because It would be too valuable to change. However a new factory .44 special would be nice to have.
