Being all stainless, the Sig is hefty and handles recoil nicely. Not sure about the 'blocky' grip on the FN though. I guess I have 'average' size hands (disclaimer: I don't, as a rule, go around checking out other guy's hands, so mine is an estimate I like the Sig build quality - alot. I could always use it as a club if I run out. I could shoot through a window - or just smash through it. probably a wall too. I have yet to find a FN 45 in a store in NJ to handle the FN, so I am a bit at a loss other than reading what others have experienced. Anybody know of a Jersey shop that carries FN 45's? Any thoughts on comparing the two? Thanks.
