After a good amount of searching, it seems the G29/30 share almost identical specifications, with the exception of the caliber they are chambered for. I've read numerous posts and comments about converting the G30 to 10mm easily. However, I never found any solid, I've done this type info. So, this leads to my questions: Can I drop in a G29 10mm barrel into my G30, and use the G20/G29 mags? Is the guide rod the same for each model? Or, do I have to go with a KKM or Strom Lake drop-in style conversion barrel instead? Any input is appreciated.
