I'm not aware of a conversion barrel but you can check HKparts.net . As far as a mags go, you can fire 9mm out of a .40 mag , NOT .40 from a 9mm . I would only do that at the range , but I would just buy the mags . The pistols do use the same lowers .
P30L 40 S&W to 9mm conversion barrel
Just curious to know if anyone owns a .40 to 9mm conversion barrel? If so, how's the reliability? Do you need to use 9mm maggs? Any other mods necessary in order to accomplish this conversion? Thank you
