Ruger's KGP-141, due to:
> The four-inch barrel is short enough for concealed carry and home defense, but marginally long enough for small-game hunting, plinking, precision target work, and field carriage.
> Revolvers (in general), and the GP-100 series (in particular), have superb reliability, durability, fit/finish, accuracy, utility, design simplicity and effectiveness (additionally, GP-100s are essentially indestructibly strong).
> .38 Special/.357 magnum ammunition is readily available and inexpensive, however, it also includes a BROAD range of uses, from cheap .38 Special target/plinking rounds, to extremely potent .357 magnum defensive (think Double Tap, among several others) and hunting rounds (for example, 190 grain cast-core medium game hunting loads).
> Post-market accessories (holsters, sights, lasers, and so forth) are readily available and relatively inexpensive (due to market volume/economies-of-scale).
