A new player in the Glock pistol-to-carbine conversion game, American Manufacturing Group, has a system for the 4 Gen Glock 17 that swaps out the barrel of the handgun with a rifle-length drop in and adds a M4 style stock-- while remaining ATF compliant.
Why a carbine kit?
Pistol caliber carbines date back to the 1850s and the concept in and among themselves are not new. Taking a standard handgun action and adding a short, rifle length (16-20 inch) barrel and a buttstock, you now have a longarm that still fires a pistol round. The stock and forearm provide a much better and more stable platform than a pistol's grip alone.
With a longer barrel, you get a longer and much more accurate sight radius. This means that basketball sized groups at 25-yards with a handgun can very easily become softball sized groups with that same handgun in a carbine configuration. With a little practice and a steady shooting position, 100-yard shots are a real possibility. You just can't do that with a standard handgun.
Vincent Chiarenza's American Manufactures Group has been around since about 2001 and markets a lot of different firearms accessories including a neat little 22LR reloader. One of their newest products is the Lock, Stock and Barrel system for the G17.
Simple in concept, it replaces the standard barrel on your Glock 17 (4th Gen only at this time), with a rifle-length 16-incher, a new Guide Rod Assembly with Accelerator and Accelerator cuff, and a Phoenix stock system that is currently considered kosher by the ATF's Technical Branch-- which means its NFA-compliant.
According to AMG, the system can be swapped out in two minutes and the changes are not permanent and is billed as improving accuracy "up to 70 percent."
On the downside, you have to use 124-grain 9mm or higher to acutate the slide.
MSRP is $299.

Now AMG isn't the only player in the market. Mech Tech has been making their basic CCU kit, which includes a 16+" barrel, internal slide, recoil spring, cocking handle and exterior rails for a generation and covers about half of the various Glock models out there. It retails for about $350. If you add their optional MonoRail, MiniRail and M4 stock with adapter to your basic CCU, you have a shootable carbine kit for about $530.
This price point makes it tempting for a the average buyer to instead purchase a separate and stand-alone Kel-Tec SUB2000 carbine that, while is not a Glock, will use your same Glock-series magazines, but runs closer to $700. New York-based Just Right Carbines has a AR-ish platform that takes Glock mags for a more affordable ($600) price point while Nevada-based New Frontier Armory (NFA) has a C-9 AR-15 billet that does the same thing and Phoenix, Arizona's very own Kalashnacon, a maker of all things custom and AK, has a blowback action pistol caliber Kalash-inspired gat that runs Glock mags (but is price on request).
With that being said, the AMG LS&B may be positioned well for those who have about $300 to drop and don't want to go through the trouble of buying a standalone carbine.
We have three vids of the platform in action, the first, by master of the tactical mohawk, Mr. Hank Strange, spends about 12 minutes walking the LS&B through its paces-- including set up and take down. The next two are AMG promo videos.
