I have a SIG 229 with .357 SIG ans .40 S&W barrels, 3.9 inches in length. Does anyone know if I can get longer barrels that drop in?

Thanks

Hi, try Brownells (http://www.brownells.com/Product/index.asp) and check out stock number 503-101-229 or type in barrel in the search window, but that pulls up a lot of results.
