Does anyone know if the SR40 can be converted to 9mm? Either with a conversion barrel or will a regular 9mm bbl work? I have a line on like new SR40 at a really good price but I don't typically buy 40 cals unless they can be converted to 9mm. I like the idea of having a two for one. I currently have a Glock 22, XD40 and SW 40 with conversion barrels. I carry 40 but practice with 9.
