I have built more than my share of "tactical" shotguns over the yrs, currently have 20 or so in the safe.
I have yet to come across a collapsable/folding stock that actually allows you to shoot practically well. They all afford making the shotty shorter and more packable and are arguably damn kewl looking but they don't shoot for ####.
Same goes for a pistolgrip. makes the shotty smaller and much more packable but is only practicall yeffective at conversation distance.
If it makes having the gun present when needed for defense purposes such as canoeing/fishing an dother cases where having the gun short and compact enough to both have with you and remain outa sight till needed then it is certainly worth the tradeoff in practical accuracy and shootability as the other option would be to not have it with you at all!
A conventional buttstock and or a pistolgrip full buttstock is the way to go if you want actual shootability and practical accuracy. The pistolgrip buttstock offers better one handed gun control when/if needed but IMO deosn't shoulder as readily from a slung or unhanded position. They also make the gun more cumbersome for packing and or scabbarding.
A short LOP conventional buttstock is IMO the best setup for a defensive and practical shooting shotgun.
If you really want/need the shortest package for packing/concealing and still want/need a practical shooting setup you can't beat a 12 or 14in pump with a short LOP conventional buttstock. This is as short as a pistolgripped full length gun and offers shootability with reaonable mag capacity.
When it comes down to reaching for a shotty in a hurry for real to stop a predator, regardless how many legs it has, I won't be fawkin' around with folding stocks/pistolgrips/lasers/red dots/picatinny rails..........
Now if the object of the game is fun and kewl factor....well then the world is yer' oyster and go nuts.....Nothing wrong with that.....that's what MOST of my guns are for! lol
