This is all there is out there about it but Hi-Point is on the verge of releasing another of their aesthetically dubious carbines in 10mm. As homely as these rifles are, they function well AND they're affordable which makes it easier for us working stiffs to own a solid PCC without denying the kids their new duds. Plus there is a (slowly) growing aftermarket of accessories including the long-awaited (but not here yet) High Tower Armory bullpup stock, an ATI stock, several grips and other stuff you can find by asking The Google. Best not to hold your breath on the carbine however as these things typically take far longer than estimated to materialize and reach our local gun shops, but it promises to be fun when it does finally get here. GOM.

ATF Information:

ATF Ruling 2011-4. This Specifies that you can not own a pistol barrel if you own just the ASR Rifle without having an SBR License. Essentially this ruling means that you can't just switch your rifle into a SBR without first going through the proper channels and get your SBR License. Click Here to get the paperwork needed to get your SBR license. 

For a nice breakdown on what this means you can check out this article from thetruthaboutguns.com. It gives a nice overview on how to stay within the law.

World Market Leaders Join Forces : UMAREX Receives GLOCK License

ARNSBERG, GERMANY (September 22, 2017) – UMAREX GmbH & Co. KG (UMAREX) headquartered in Germany receives the first worldwide license from the well-known Austrian weapons manufacturer, GLOCK, for the reproduction of its internationally recognized pistols. UMAREX is thus writing a new chapter in its success story as the world market leader in licensed replica handguns. Eyck Pflaumer, managing partner of UMAREX, summarizes the results of the intensive negotiations, “For years now, the trust between our two companies has been growing and we are looking forward to further developing this relationship with GLOCK. From November 2017 onwards, gun fans will find the first replicas of these famous pistols in outdoor retail locations almost everywhere in the world.”

Founded in 1963, GLOCK has been setting the global standard for handguns with polymer frames for decades. UMAREX and GLOCK are two world market leaders meeting on equal terms, the best prerequisites for a successful partnership. UMAREX will in the future build the famous GLOCK pistols in the categories "Airguns" (4.5 mm / .177) and "Airsoft" (6 mm). GLOCK replicas will be distributed worldwide through sporting goods dealers, except in France and French territories. Umarex USA and the Elite Force Airsoft group of Umarex USA will distribute the world-leading GLOCK pistol replicas exclusively throughout North America. Distribution in the USA is expected to begin first quarter 2018. Particularly attractive for collectors, the license allows the replicas to carry the original markings and be marketed in authentic packaging.

This from the HK website:

The eagerly anticipated subcompact model of the acclaimed Heckler & Koch VP Series handgun, VP9SK (in 9 mm) has all of the sought-after characteristics of larger frame VP pistols but in a more concealable design.
The highly-rated HK VP precision strike trigger is also found on the VPSK. The VP trigger surpasses those found on competitors. It has a short, light take-up with a solid, single action type break followed by a short positive reset. The net result is trigger quality unmatched in production striker fired pistols.
A small-scale interpretation of the completely adjustable VP grip feature — consisting of interchangeable backstraps and lateral grip panels — is replicated in the compact grip frame of the VP9SK. This allows the pistol to be easily modified to fit any individual user and is a feature found only on Heckler & Koch handguns. Molded finger grooves in the front of the pistol’s grip also instinctively position an operator’s hand for optimal shooting.
The VPSK has the features of the latest, state-of-the-art handgun. All controls are completely ambidextrous. Slide releases are present on both sides of the frame and the paddle style magazine release can be easily activated by left- or right-handed shooters.
HK’s patented charging supports, found on full size VP pistols, are also present on the VPSK. The charging supports are simple components that are mounted on each side of the rear of the slide and provide better gripping leverage for racking the slide rearward. The charging supports speed reloading and make operating the VP easier for shooters with reduced hand strength.
VPSK pistols can use a variety of proven HK magazines, including compact double stack 10-round and 13-round with either flat or extended floorplates for a more ergonomic grip. The VPSK can also use the same high capacity 15-round magazine used by the full size VP and P30 handguns. Magazine sleeves that replicate the grip profile of the VP handgun are also available.
VPSK pistols have an abbreviated Picatinny MIL-STD-1913 rail molded into their polymer frame for mounting lights and accessories.
VPSK pistols use a proprietary captive flat recoil spring that helps reduce the recoil forces affecting the operator and the handgun, improving shooter control during rapid firing and prolonging component life span.
HK’s famous cold hammer forged barrel — made from cannon grade steel — ensures a long service life. Similar HK barrels on 9 mm P30 models have fired more than 90,000 rounds in endurance tests in 2010. The polygonal bore profile, with no traditional lands-and-grooves rifling, contributes to longer service life as well as a slight increase in muzzle velocity.
The VPSK’s machined steel slide is protected from corrosion and wear by HK’s hostile environment finish and all metal components, including springs and pins have superior metallurgy.
Despite their small size, VPSK subcompacts have excellent weight and balance making them naturally pointable, easy to control, and accurate to shoot. VPSK models are currently available in 9 mm.
VPSK pistols are made in Heckler & Koch’s Oberndorf factory in southwest Germany and are well suited for civilian sport shooting, security, military, and law enforcement use.
A high quality and well-engineered design, the VP9SK possesses all the features and long-term durability that make HK products especially cost-effective when subjected to total life cycle cost analysis. And like full size VP pistols, the VP9SK is value priced at $719 (MSRP).
Available Configurations
Part No. 700009K-A5, VP9SK, 9mm with 1 flat and 1 extended floorplate 10 round magazines – MSRP $719
Part No. 700009KLE-A5, VP9SK, 9mm with 1 flat and 2 extended floorplate 10 round magazines with night sights – MSRP $819
NOTE: 13-round and 15-round extended magazines will be available November 2017.

As per the GLOCK website: ​

FIVE DISTINCT FEATURES
More than 20 design changes distinguish the Gen 5 pistols from their Gen 4 predecessors. Among these design changes are five distinct features which deliver an improved overall shooting experience and propel GLOCK into its next generation of pistols. Learn more about these new features below.

NDLC FINISH
The GLOCK 17 Gen5 and GLOCK 19 Gen5 feature the proprietary GLOCK nDLC finish. The ion-bonded finish reduces corrosion and scratching and improves performance in adverse or de-greased conditions.

GLOCK MARKSMAN BARREL (GMB)
The GLOCK 17 Gen5 and GLOCK 19 Gen5 feature the GLOCK Marksman Barrel. The barrel’s new rifling and crown deliver improved accuracy for both the beginner and the seasoned gun owner.

NO FINGER GROOVES
The GLOCK 17 Gen5 and GLOCK 19 Gen5 have no finger grooves on the grip. Removing the finger grooves improves the ergonomics of the grip, delivering consistent comfort and improved control to a wider range of consumers, regardless of hand size.

FLARED MAGAZINE WELL
The GLOCK 17 Gen5 and GLOCK 19 Gen5 feature a flared mag-well. The larger opening found in the mag-well of GLOCK Gen5 pistols makes quicker and easier magazine changes possible, particularly in high-stress situations where fractions of a second matter.

AMBIDEXTROUS SLIDE STOP
The GLOCK 17 Gen5 and GLOCK 19 Gen5 feature ambidextrous slide stop levers. Now it is easier than ever for both left-handed and right-handed gun owners to quickly, comfortably, and safely manipulate the slide.
