I had a 342ti, but upgraded to the 340sc. Great to carry, not fun to shoot. Even .38's are somewhat rough, but .357's are downright painful. Love the gun, carry with full house .357's. If I ever need to use it in self-defense, I'll deal with the slight soreness in my palm. This is not a target gun, and is not intended for 25 yard head shots. For it's intended purpose, I can control the .357's sufficiently to feel comfortable.
BTW, if I recall, the barrel of the gun says not to use loads with less than 125 grain bullets.
