That video did confirm that rear sling mount is in a terrible place. At one point he had the gun just hanging by the sling and the gun had completely rolled over with the trigger group pointing up. If you try carrying it like you would an AR15 you would have to reach under the gun to grab it and roll it back upright as you bring it up. Beretta should have placed a sling mount on either side of the stock and not on the bottom. I think that will be a deal breaker for anyone who needs to carry it slung.
I've modified several guns to add QD sockets to hollow polymer stocks. It really isn't that hard and I've got a couple more to do in the next month. I like this one the best.

Remove the buttplate, decide where you want to put it, make sure you don't have a stock bolt in the way. Measure twice, drill once. On this particular one, as I recall they say use a 1/2" drill. The cup is little larger in diameter so I've used a round file to chamfer the edge and open the hole up just a little. A hex wrench fits a hole in the middle and I bear down and thread it into the plastic. That takes some back and forth, but I think it is more secure than just enlarging the hole. "Screw" it down using the hex wrench, put a little locktite on the threads and then install the nut on the inside. Easy-peasy. I've got a synthetic Ruger GSR stock arriving tomorrow and I plan to add one to each side for flexibility, though I could get buy with just one. I'm going to install a different cup in the forend. I've also got a Fight-Lite that uses a Remington 1100 stock and I'm doing the same for it.
Got a chance to shoot a few Brenneke slugs at 50 yards. A three shot group with two overlapping, about 2.5 inches. I need to do more and compare with my 1301 but this is shaping up to be a competent slug gun. Functioned with an 8 pellet low recoil load but limited rounds fired again. So far, this is totally a good lower dollar choice.
My apologies to weasels.
Most stocks that are properly short, and low enough to use typical shotgun irons or cowitnessed dots, will result in popping yourself in the cheek/nose with your thumb if you wrap it around the grip. Given there's little if any need to do so to control the weapon, I generally advise not wrapping the thumb for just that reason.

...and here I thought the British put to paper everything we needed to know about Shotgun Fit over 100 years ago...FWIW, their dictum of having the forward-most portion of your cheek 1 to 1 & 1/2 inches BEHIND the rearmost portion of the heel of your hand that's likely to touch your cheek was good advice 150 years ago, is good advice today and will be good advice in another 150 years--UNLESS, of course, you LIKE getting "Popped" in the Cheek & want to develop a pretty good-sized FLINCH--Then, by all means, "Knock" yourself out!
