FAB Defense, Israeli manufacturer of weapon accessories such as the KPOS pistol chassis and the Pentagon Magazine Kit, and subsidiary of The Mako Group, have introduced a variant of the KPOS that is compatible with SIG-style braces, offering a convertible pistol-caliber carbine package that is short, handy, and – most importantly – not an NFA item. From the press release:

FAB Defense, the leading name in developing and manufacturing high quality, cutting-edge tactical equipment and weapon accessories for Israel’s military and police, introduces their latest innovation-the KPOS G2P Pathfinder.

The KPOS G2P Pathfinder is the second generation of FAB’s popular KPOS PDW Conversion Kit. The Pathfinder replaces the buttstock on earlier models with a folding rubber stabilization tube. This innovative design provides defense and security minded shooters with the benefits of the KPOS system without the restrictions of SBR laws, so it is perfectly legal without purchasing a special federal tax stamp.

The KPOS Pathfinder PDW Conversion Kit converts your handgun into a PDW-Personal Defense Weapon. Constructed from a solid piece of 6061 T6 billet-hard anodized aluminum, the Pathfinder includes rear/front backup sights and versatile tactical support. A built-in AR15-style charging/cocking handle mechanism makes it both ambidextrous and easy to use. It requires no special assembly or handgun modification and the removable front flash hider for silencer/suppressor attaches with a single bolt. Folded or open, the Pathfinder is the smallest and lightest frame compared to any alternative.

There are model-specific Pathfinder conversion kits available for the following weapon brands: Sig , Glock, FN , Beretta, SpringField, CZ, and Jericho.

The KPOS Pathfinder PDW Conversion Kit is distributed in the U.S. exclusively by the Mako Group. Dealers and distributors looking to enhance their line of quality conversion kits are invited to stop by The Mako Group’s Booth #20043 at Shot Show or call 631.880.3396 ext. 310 for immediate assistance.

I’m having a very difficult time calling this one. On the one hand, pistol caliber carbines tend to achieve limited success at best, due to combining the size and weight of a rifle with the impotence of a pistol. However, the Pathfinder is a little different. It’s a pistol, not a rifle, and as such can have a much shorter barrel than a rifle. Further, unlike most pistol caliber carbines, it does not require the purchase of a separate weapon; your “carbine” is your pistol.

MSRP has not been announced yet, but the older NFA chassis have been retailing for a little over $400. I think that’s on the edge of being cheap enough to really attract attention. If the MSRP of the Pathfinder ends up being even $50 cheaper, I would expect it to become reasonably popular.

    Man, if pistols with stocks could be a reasonable length we wouldn’t need silly items like this.

    • Sometimes people forget how small M11A1s are. Little flush fit mag and you have a rocking little rig for taking on Crockett and Tubbs.

  • Ethan

    The advantage being a sig brace and a good place to mount an optic.
    Kind of a niche gun IMO, but for $400 it’s definitely priced right.

    • Marty Ewer

      Personally, I think the Shockwave Blade pistol stabilizer would look better. 😉

  • Ethan

    Agreed. If 5.56 were the only thing out there I could see the value, but today there are so many great calibers that achieve superb results out of short barrels: 300BLK, 6.8SPC, etc..

    While I do love a caliber that’s easy to reload and cheap enough to shoot all day (9mm), it wouldn’t be my first choice for defense.

  • The new modular Masterpiece Arms Mac’s are a better option IMO. Modular grips take Glock mags, and can also be converted to 5.7×28. Same price as the pathfinder, but it’s a complete firearm. In terms of specs, it’s 2″ shorter with an 8″ fixed barrel for better accuracy and higher velocity. And it can accept a brace as well.

    • Nicks87

      Too bad the MPA30DMG weighs 8lbs otherwise I would agree with you.

      • It weighs 3.8lbs, or 4.2 with the 8″ barrel. The KPOS weighs 2.2lbs without the glock; when the G17 is added the weight difference is negligible.

  • Darren Hruska

    One of the earliest examples of the modern PDW, the Colt Small-Caliber Machine Pistol (SCAMP), was practically a bulky pistol for the most part. Also, another early PDW from Colt (predating the SCAMP by a year or two), the Individual Multipurpose Weapon (IMP), lead to the Bushmaster Arm Pistol. Then you get into the stocked machine pistols, such as the “Broomhandles,” that some may also attribute to the PDW concept. So, the idea of a “pistol-based PDW” isn’t new, but it’s still something that really hasn’t hit the civilian market all-that-much. This product shall hopefully fill a niche that civilians just never got many chances to experiment with yet.

  • why convert a small pistol into a larger pistol that doesnt actually have a longer barrel?

    • F = ma When you increase the mass, you decrease the recoil force. This equation also describes inertia. It is harder to push a heavier firearm off target than it is to push a lighter firearm (jerking the trigger).

      Also, longer sight radius for increased accuracy, and peep sights are usually faster than notch and post.

      Just trying to see the bright side.

      • fair enough, I would just think that if you were going to pay 400 dollars to convert a pistol to a carbine length contraption, you should at least get a longer barrel to get smg type barrel velocities.

    • So you can have a stock brace and a longer sight radius.

  • This is the SIG brace compatible variant.

  • JSmath

    Hinted at in the description details. The flash supressor is removable just in case and, I believe, approximately larger than 1.75″ ID, incidentally.

  • JSmath

    The first I saw these conversions, I absolutely hated them and their intended market niche.

    But honestly, there are a few combinations of particular features that make them seem honestly pretty nifty in their own right. Definitely not shelling out the money for such a thing until I’m filthy rich which isn’t happening anytime soon. ;]

  • Squirreltakular

    I’ll stick with my Sub-2000. 😉

  • Franciscomv

    These kind of chasis are quite popular in my country, because they are the closest most civilian shooters can get to owning a semiauto rifle/carbine with detachable magazines.

    They are expensive (down here a Roni costs about as much as the handgun you put inside it), but they sell well (considering how tiny our gun market is).

  • gunslinger

    it almost looks like it’s facing backwards

  • Brian

    Why not just get the MechTech conversion for $400? You get a stock and long barrel.

  • Alex

    You need to loosen up the tinfoil hat. You really think a prosecutor or DA wants to go in front of a judge and push a case (based on Intent) that more likely than not he’ll lose? I think you might see the ATF write ambiguous opinion letters with the intent of scaring as many people as possible out of buying braces. But the idea that a prosecutor is going to bring someone to court singularly because he put a pistol to his shoulder is laughable. What if he was “cheek welding” the weapon instead of shouldering? And In what situation is a cop going to charge you? Most cops dont sit around ranges looking for infractions and most cops dont even know what an SBR is, and the ones that do know what an SBR is know exactly what the Stabilizing Brace is. It’s been around for almost 3 years now and who knows how many thousands of braces have been sold. How many cases of someone getting accused of making an illegal SBR are there? How many people were accused before the brace even existed? Because you know everyone who bought the AR pistol was shouldering it with their “cane tip” (wink wink) saddle stock (wink wink) etc etc etc…

    • Rick

      yes, I DO think a DA (many actually) are looking for a reason to burn someone for political gain. Ever seen all the specious charges against defensive shooters because of the gun or ammo they use? have losses slowed these down yet? or are the chilling effects (and even some successes) working out for the overzealous DA’s?

      • Alex

        I’ve never seen any of the specious charges against defensive shooters you’re talking aobut for the gun or ammo they use in a “good” shoot. If you have some examples of those I would very much appreciate them. I also know of nobody that has every been speciously charged for using an AR pistol like an SBR (which is what we’re talking about here)….and AR pistols have been out for 20 years now. In fact, this Brace thingy has nothing to do with whether or not you could possibly get charged by making an SBR. The charges would stem by placing the weapon to your shoulder, not placing the Brace to your shoulder…as the brace in every ATF letter has been determined not to be a stock. And as I mentioned before, I really dont think any prosecutor would want to go in front of a judge and try and convince him that placing a pistol on your shoulder creates a felony…but hey, to each his own opinion…if you truly think you put yourself at risk by shooting a pistol “inappropriately” don’t shoot a pistol inappropriately.

  • Rick

    expensive, and makes the pistol a lot larger while adding nothing to the barrel. All of these dress up kids put a big showy shroud extension but nothing else.

    I prefer the upper slide type conversions myself. Ones that have longer barrels, look less like something on Syfy, and don’t pretend to sneak around any SBR rules. I’ll be a big boy and make sure I’m in compliance, I promise. 🙂
