I believe the 2" 12 was actually developed before the 2" gun. My interest in it was based not in ballistic performance. I wanted one. Thats it. The scale in the gunsmiths shop settled at 4lb 14oz. This light weight forced me to adapt to the gun. Old sight pictures became useless. A smooth mount to the front with shot almost immediate is how I can best describe it. No, I bought that gun because it looked like it would be fun. That it worked out so well was a happy accident.
