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.)

2012, in review

It is that time of the year again… Just like all the previous posts like this one, I am using Google Analytics data, with the same warning that its numbers do not match the numbers generated by other statistics engines. Likewise, we will compare numbers against last year.

Absolute Unique Visitors: 94,843 (35% increase)

Visits: 174,805 (9% increase)

Peak Daily Visitors: 1,549 (23JAN12) (27% decrease)

Average Daily Visitors: 478.92 (9% increase)

Pageviews: 244,249 (not tracked previously)

Total Posts: 512 (46% decrease)

And speaking of discrepancies, StatCounter shows 203,477 unique visitors, 273,178 visits/pageloads (they do not appear to differentiate), a peak of 1,964 on the same day, and an average of 746 visits a day. On the other hand, WordPress’ stat engine shows 280,000 pageviews total and a peak of 2,187 views on 23JAN.

All said, it was a somewhat quiet yet for "walls of the city"; apparently my posting dropped by almost half, but, conversely, my readership picked up between 10 and 35%, depending on which statistic you think "counts". I guess this means I put more value in my individual posts, or just that I have larger archives for more people to go digging through.

Speaking of archives, three of my top-ten posts are not from this year, and two are from 2010. Interesting.

The two big traffic bumps this year occurred when Instapundit linked to my post about how Florida concealed carriers are more law-abiding than Mayors Against Illegal Guns members and when I exposed the fetid pile of waste that lurks beneath the surface of The Truth About Guns. I am not entirely sure what, exactly, that says about what you folks like to read, but I suppose it says something.

And as for the search terms people use to find this site… well, I have nothing positive to say.
