My understanding is the CPO Sig's are usually worth the money. I've got a local guy who is a Sig dealer offering a CPO P229 in .357 for $550 (taxes and everything) He said he has a new .40 barrel for it that would run me $675 for both. Is it worth the extra $125 or should I just use it as a .357? My brother has the P229 in .40 and my intention was to just get the same thing. The price seems pretty good for the .357, just wasn't sure if the barrel was worth that.
