So ive done a lot of shopping around and am pretty interested in a ruger. I really like bull barrel on the ruger 22/45. I just have 2 questions what is the difference in the 22/45 and the mark 3. I know the 22/45 has a grip the resembles a 1911 style pistol but the price difference is $150 between the 22/45 and mark 3 and im not sure why. I also am not sure whether to purchase the 4.5 or 5.5 inch barrel. Any help would be much appreciated.
Thanks
