Get the Taurus, all the way.
If you want 357 Sig, GET A SIG!
I have a Taurus 454 Casull, makes the 357 look like a peashooter

I use it for hunting dangerous animals (boar/bear/etc)
For other stuff, I have my HK USP45, never failed, tougher than anything else I've had.
Glocks are *nothing* compared to HK
