I was working for a gun shop when the L frame problem came up. As I had recently attended the S&W armorers school, S&W wanted to know if I would take on the recall work. I said yes and ended up doing around 600 revolvers, for LE agencies and customers who brought their guns in. The gun shop owner and I split the fee S&W gave us and he covered the insurance as well. I still have all the tools and lots of the replacement parts left. I had one gun, out of all of them that I worked on, that I could not get to work correctly after the modification. Ended up sending it back to S&W and they had to replace the frame. The gun belonged to our local Sheriff's Dept. S&W also provided all the .357 ammo needed to check out the modification too.
