Thanks for the pictures comparing the 2 models. If money isn't an issue, I think choosing the 340 is a no brainer. Sure it kicks with .357 loads like a beast, but that's the compromise between the 340 and any gun that weighs 50% more. The barrel length also makes the 340 slightly more concealable.
More concealable it may be, easier to carry it certainly is. But if you don't practice with what you carry when the time comes you won't perform properly. And who owns a 13oz .357 Magnum snubby that practices with full house .357 Magnum ammo? And by practice I'm not talking about 50 rounds of low power 38 Special ammo then 5 of .357 once a month.
If you don't practice with your carry ammo, or something very similar, you will NOT run it properly when the SHTF. Snubby owners seem to think that rule doesn't apply to them. The SP-101 makes practice with hot ammo not only possible, but fun.
