...The story goes that porting increases muzzle flash, and it's true; to some degree.
While it does increase muzzle flash, stop action photos will show that the flash typically doesn't ignite until it's a ways above your line of sight. Yeah, you still get that extra flash, but it's not nearly as bad as people say/think it is�.
�..porting makes shooting from retention exciting and often memorable�..don't ask me how I know.
Oh yeah, I forgot about that...just a tad hard on clothing...eyebrows, hair, etc.
Did that with a comped .356 TSW single action S&W 59 conversion...ONCE. Ruined a pair of Oakley's, and they're still looking for my hat.
