Really a 1.20!?!

I would have thought the weight penalty would be a little too high. If I was going to go bigger displacement I would think a better size more like a Magnum or ASP 1.08.

So basically here's what I've thought of:

ST 75
ST 90
GMS 76
Magnum 1.08
ASP 1.08

Supertigres may be hard to come by

GMS & ASP don't have the greatest reputations

Magnum 1.08 might be overkill

What do you guys think?
