Ok so I know this cartridge was designed for the complete opposite purpose - super high velocity. However, I'm getting a 9mm can this year and got to thinking, could it be done?
I see doubletap has a 180gr 9x25 load coming in at 1200 fps from a 6" tube, considering how hot they load most of their ammo, could a load like that be made subsonic with a minimum powder charge? Or maybe even with a 147gr pill? My question isn't whether or not it would cycle the slide, just if it could be done.
