I first want to say this is not a 9MM vs. .45 debate,rather I'm interested in which of these guns is more concealable and lighter. So I'm considering which of these to purchase and can't decide on one over the other. Between these two Sig which is the better of the two? I kinda of like the P239 for its small size and because being a 9mm ammo is less expensive and plentiful. So for those here who have both of these Sigs or experience with them both please sound off on the pros and cons thanks.
