It's not as instinctive as a classic SIG, and doesn't ooze quality through it's pores, but it's as accurate (Or more accurate), and I really can't say I regret buying my 2340.
I have a SIG .40 barrel for my 357SIG 2340, and a 9mm bar-sto barrel for it, making it a 3 caliber gun.
With the 2340 in 9mm mode or 357SIG mode, it shoots like a laser, and the .40 isn't half bad, either.
I just like guns that were designed for the caliber they shoot, not just retrofitted from 9mm frames.
Oh, and it happens to outshoot my 228 and my 229.
I think it's prolly one of the most underrated guns out there right now.
Big fan of the 2340.
