I am mainley into blackpowder, but, have this incredible urge to buy a modern handgun. I have it narrowed down to a ruger gp100 or a sp 101. I will not use this gun for hunting, (will stick to the blackpowder for that) I am thinking a .38, less recoil and noise than a .357. I know I can buy a .357 and shoot .38 bullets out of it, but will it be as accurate? What I am trying to say is will a .357 shooting .38 shells be as accurate as the same gun chambered for .38? I will use this gun for home defense and carry for walks in the woods. I am really leaning towards the sp 101, mainley because it is lighter. I did handle a sp 101 at a gun show with a 3-1/16" barrel and really liked the way it felt in my hand, it was a .357, for 400.00, was just unsure if it would shoot .38 ammo as accurate as the same gun chambered for .38. Any help would be appreciated. chuck-ia
