Given the relative price / non-existence of pistol-caliber ammunition these days (up to and including, shockingly enough, .22LR), the rational behind these awesome little toys is somewhat more… lacking, but, still, want:
Converts 12 gauge single or double barrel (break action) shotgun to use 9mm Luger
Rifled for accuracey
Typically shoot’s a 1 inch or less group at 30 ft.
Length of adapter is same length of a typical 12 gauge shell allowing to fit in ammo cases easily
Fits any brake action shotgun that can shoot a 2-3/4 or 3 inch shell.
CNC Machined for precision!
Made in Miles City, Montana USA !!!
Made from Alloy steel!
Three inches long with Rifling
Makes your 12 gauge more versatile for cheap!!!!!
The gentleman behind the ShortLane Chamber Adapters sells them in a variety of lengths (3″, 5″, and 8″), in rifled and smoothbore configurations (the latter being cheaper but less accurate), for basically all the standard shotgun sizes (10, 12, 16, and 20 gauges, along with .410) and even some of the whackier revolver calibers (.500 S&W and .480 Ruger), and capable of chambering pretty much anything from .22LR all the way up to 20 gauge, depending on the overall configuration. They are designed specifically for break-action shotguns – side-by-sides, over/unders, or single-shots – but I suspect, and the reviews seem to indicate, that the 3″ adapters can be used in any pump-action shotgun capable of chambering 3″ shells.
Obviously you are “wasting” at least 10″ of your barrel even with the 8″ insert, but I have to wonder what the shotgun barrel extending past the insert barrel would do in terms of the report… It is certainly no suppressor, but something will change*. And, in any case, you are greatly increasing the flexibility of your shotgun.
Which is what the folks at The Firearm Blog, where I found these little gadgets, were driving towards – making a “survival” shotgun a reality. A lot of folks automatically jump to “shotgun” as their default answer for zombies / bugging out / apocalypse / etc. scenarios, and there is a lot to be said for that particular platform… as well as one glaring problem: ammunition. Shotgun shells are large and heavy, and you yourself are not going to be able to carry too many (in addition to everything else you might be carrying). However, enabling your shotgun to shoot pistol-caliber ammunition while still having buckshot or slugs for more serious applications? That rapidly increases your potential round count while not significantly increasing – or possibly even decreasing, depending on the masses involved – the weight you are carrying.
And while I do not want to take business away from the originator of this shiny idea, I have to wonder if something similar could not be fabricated on a 3D printer… Obviously rifling would be impossible, and the lifespan of a plastic insert would be significantly limited, but if we are talking about “bug out” applications, it may not need to last long. And, of course, testing with a 3D printer and a backyard range makes my little footnote below still quite illegal, but a lot less easily noticed…
Now all I need is a break-action shotgun… I have been eyeing the Stoeger Double Defense series for a while now (Come on now, did you expect anything else from me? I just wish they made a Quadruple Defense, because that would be epic.) but now Mossberg has introduced the HS12, their own variation on that theme (though the latter benefits from not having a safety that automatically engages every time you reload the firearm – why do o/u shotguns have that bit of idiocy built into them?). Hey, at least double-barrel shotguns are something you can actually reliably find these days, though, of course, those two models are sold out almost everywhere…
Yes, I do have a taste for the peculiar. Why do you ask?
(* – On the flip side, I have to wonder how hard it would be to machine an insert like that and add 4-6″ of suppressor-like baffles at the muzzle end of it… Obviously such a thing would be strictly verboten without the appropriate licenses and tax stamps, but for someone with a lathe and a bench-press drill, it would not be that hard to make… or modify an existing insert to have.)
