I know that this probably sounds crazy. And right about now you're probably thinking "Jesus Rambo! Lose the war paint and chill out a little" Well, please allow me to explain... ...my father in law isn't much of a "gun-guy". Outside of his 2 or 3 hunting rifles, the only handgun he owns (that I know of) is a Smith and Wesson .44 Mag with a 5-6" barrel. I looked on impactguns.com and this was the closest match I could find. http://www.impactguns.com/store/022188636369.html Now, he uses this gun for concealed carry, as well as vehicle / home defense. In the near future I would like to help him make it a little more practical if you know what I mean. I thought that the addition of an accessory rail would be nice. That way, he could mount a streamlight or similar weapon light to his gun. Thanks for your help!
