Welcome to 2012!
In 2011, the subject of pistol-caliber carbines came up here at YGN, as well as on other gunblogs.
While people have different preferences, most seem to agree that the selection of factory-new offerings in this category of gun is pretty sparse.
A prospective buyer has few options to choose from if they want a new gun:
Kel-Tec Sub2000 in 9mm or .40S&W (The Kel-Tec has the advantage of using pistol magazines from one of 4 manufacturers)
Hi-Point Carbine in 9mm, .40S&W or .45ACP. (Rough fit & finish, but reliable enough according to people who have tested it)
HK USC in .45ACP (Expensive, well-made, allegedly not as accurate as a gun that expensive should be)
Beretta CX4 Storm in 9mm, .40S&W and .45ACP (Great appearance, accuracy unproven, some ergonomic issues with access to controls)
A pistol-caliber AR-15 or replacement upper. There are 2 camps of pistol-caliber AR-15s: ones that use a full-size magazine to fill the entire 5.56mm-size magwell (as Olympic Arms does) or the ones that use Sten/Uzi magazines and a modified lower (the Rock River Arms and the company that calls itself Bushmaster approach) or a magwell adapter (Colt’s approach) to make them fit.
Or one of the Cobray/Leinad CM11 (MAC-10/11 knockoff) kit guns that I have heard bad things about.
Well, now there is a new option for these customers to consider: The Thureon Defense Carbine.
A closed-bolt blowback design, the Thureon Defense Carbine uses AR-15 trigger components, which might mean that the trigger group can be changed like it can on the AR-15. It uses Colt 9mm AR-15 magazines.
Gun Tests magazine says they are testing one. Time will tell.
It isn’t as ugly as the Leinad/Cobray CM11.

Hi, Sorry I could not figure out how to reply directly on the comment page on your recent article concerning pistol caliber carbines (some Ar-15 Style). So… Please publish my post as it was well researched and based on personal experience. Many Thanks!
“I did a HELL of a lot of research before buying my Thureon Defense .45 carbine. I really wanted a .40 but after calling 15+ distributors nationwide, nobody had any. I SCORED a .45 withmy desired option in Texas and that was cool as I have lots of .45. I already own 3 AR-15 rifles…. one in 5.56, one in 6.8 and an AR-57 ….which fires a proprietary round made by FN). OBTW, I have one ugly Highpoint .40 carbine which is ONE HELL OF A LOT OF FUN TO SHOOT, not to mention with the Sig strobe fwd grip I have on it I have no doubts I’d blow the crap (brains) out of anyone that decided to enter my place unwelcomed at the wrong time. Ok, to make a long story short, IMHO, Thureon Defense makes the highest quality pistol caliber carbines available. Plus, THEY CARE! If you contact them, one of the owners answer the phone and/or they reply same day to any inquiry. I picked up my .45 Saturday, put about 200 rounds through it and after adjusting the impact point of the Aimpoint Optic, OMG, I want to kill something! My ONLY complaint is that the trigger is WAYYYYY stiff! I have Timneys in my AR’s and I am used to approx a 4 pound pull. This trigger pull lasted FOREVER and reuired a lot of effort after 200+ rounds. My finger actually got sore (call me a pussy).
Richard, we won’t call you a pussy. People who whine that the factory Glock trigger is too heavy are pussies.
