I bought this gun mainly to carry in my rv, in my opinion it is the vary best gu n to carry in a rv. Taurus is the only one as far as I know that makes it in a 3in magnum s&w makes this gun but it will only shot two and one half inch shell you. Can't use three inch magnum shells. According to the the experts that test guns say y if you are going to buy one make sure you buy the three inch magnum it has mutch better penitration witch is needed . I don't agree with the previous review that the 45 long colt is not vary accurate it is vary accurate I would put it up against any pistol caliber. You can load your cylinder in any rotation you want between 410 3 in magnum or 45 long colt and ii think you have the best protection you could ask for. You cannot conceil this gun so if you plan on carting conceived you better have a conceived carry pistol with you. Ido not take my rv any ware with out this pistol being with me.
