I am about to purchase my first handgun and I think I have decided on one of the ruger gp100 .357 magnum revolvers. Howerever, my final decision is between the 4 inch barrel with adjustable sights and the 3 inch barrel with fixed sights. The gun will primarily be used around the house target shooting/plinking but will occassionaly be carried. I was going to just get the 4 inch but think it would be too big to carry. So my two main questions are would/does the 3 inch version have substantially more recoil then the 4 inch version? Is the 4 inch barrel going to be more accurate? Does fixed sight versus adjustable sight really matter? Thanks for the help/
