Hi Steve,

I have a MagnaPorted 3" m65. A great gun made worse IMO by the porting. The muzzle flip is improved using full-house loads, but is minimally affected by lesser loads. However, the amount of muzzle flash and greatly increased noise really diminishes the utility of the firearm for anything but outdoor/daylight use. It doesn't help to have faster recovery time between shots if you can't see your target.

Best Regards,
Roger
