45 ACP, I've never met anyone who can run a PGO shotgun as well as they can a standard stocked shotgun, but then I'm only 64.
And my experience with teaching people to shoot shotguns is a mere 500-1000 qualified personnel.
IMO, if you think a shotgun equipped with two handles instead of a stock is adequate for personal defense, I think your setting your expectations way too low.
Any reasonably proficient shotgunner should be able to do this.....
At 10 yards, hit 5 paper plates or 8" steel targets with good solid hits and do it in less than 5 seconds.
Some of us, including one 12 year old,80 lbs bundle of determination named Maggie I know, can do that in much less time. I would probably do it around 3.5 seconds, if my arthritis wasn't kicking. Maybe even 3 seconds on a good day.
Some of the 3 gun folks do it under 2 seconds. None use anything but a stocked shotgun.
So try that, with a real stocked shotgun and yours with the handles. Betcha times are a lot different and hits way harder to come by with the handles.
I forget the Latin, but Col Cooper wrote of Power,Speed and Accuracy being the triad of good defensive shooting.
Shotguns are powerful. It's up to us to control that power, to place that power where it needs to go and to do so before anything awful happens.
As for ease of handling, until we develop bionic forearms that telescope like an AR stock, the lack of a stock offers no advantage in use. It is easier to store in tight quarters.
We go through this debate every few months. Please check the archives for more input.
Raj, at typical HD ranges, spread is minimal. Here, with my load of choice, it's 5-8".....
