I got the fiancé a new m&p the other day so in trade I get to buy a new handgun. I've been wanting a sig p226 for awhile but Im having alittle trouble deciding on which caliber. 9mm isn't an option for me as I already have a few 9mm's so I'm debating between .40 s&w and .357 sig. This is just for a general defense and fun gun. So I guess what I'm asking is what are your opinions of 40 s&w vs .357 sig?
