I've had three M12s over the years. I had factory CYL 20 ga. that I foolishly tarted up with a Simmons rib and then sold it. Then there was the Featherweight. Currently I have this 1959 16 ga. Mod. Fine dove gun but choked on Herter's shells on a snipe hunt year before last. Works fine with RGLs. This photo of it and Abby was taken too long ago on a great January morning dove hunt in the cold wind. Only 4 guns showed up and we had a fast and furious hour and a half of doves. A memorable hunt.
