I love my High Power and currently have a hot nut for the .357 SiG cartridge. I have a .40 S&W HP and am thinking of buying EKF Fire Dragon barrels in .357 SiG and 9mm so I can shoot .357 SiG and 9mm +P+ rounds out of the beefy .40 S&W platform. Has anyone tried this? Any problems to report as far as feed or function go? I don't want to spend a few hundreds of dollars making a good HP into a jam-a-matic. :arrow:
