Last week I bought this Ruger SP101 in .357 mag with a 2.25" barell, and shaved hammer spur. It will be my main carry weapon... my last line of defense. ( as far as firearms ) Why did I choose this gun ? Well, the short barell and shaved hammer are for conceal and carry puposes. Other than that the Ruger SP101 is a tank of a gun... @ 26 ounces empty, it handles recoil nicely. It's been produced since 1993, and has nothing but good reviews... so I got it for reliabilty. Of course, being .357 mag it will also fire .38 spl and 38 +P rounds...( aswell as the .357 "shotshell" rounds, which are weak, but may take out a squirl or other small game in a survival situation. ) which makes it versatile in SHTF situations where ammo may become scarce. IMO a quality revolver is the best choice for defense, especially in a long term survival / WROL situation. Why ? Because it will simply be more reliable. Don't get me wrong... all my other guns are semi-auto, in good quality brands. Beretta, Kimber, etc. But this revolver gives me the most peace of mind and backs all the others up.
