Does anyone know if you can use a 357 sig barrel from a Sig P-229 in a Sig P-239 chambered for 40S&W without any problems...?........I bought a bar sto 357 sig barrel for my p-229 which is chambered for 40sw and would like to try it in my sig 239 which is chambered in 40sw.,,,,,besides being slightly longer, do you think it will work? I haven't gotten the gun outta layaway yet so I can't try and put it in the 239......just wondering if its been tried yet..?
