GForce Arms launched the Jawbone in .45 ACP at SHOT Show 2026 as a 7-inch braced pistol. The May 2026 announcement adds a 5-inch barrel variant and confirms both SKUs are shipping to dealers nationwide. The 5-inch (GFHYB545) is the new entry; the 7-inch (GFHYB745) was the original release. Pricing holds at $599 MSRP across both, and street price is already trending under $520 at early-stocking dealers.

The Jawbone is GForce's American-made hybrid pistol family, built around an aluminum-alloy receiver, a closed-bolt blowback action, and Glock-pattern magazines. The platform launched in 9mm and now scales up to .45 ACP using Glock 21 and Glock 30 magazine geometry. Capacity sits at 26+1 with the included KCI stick. For shooters who want a budget-priced pistol caliber carbine that runs cheap pistol mags and threads for a suppressor out of the box, the Jawbone's price-to-feature ratio is hard to ignore.

The 5-inch is the right pick if your primary use case is vehicle storage, home defense behind the bedside table, or a compact suppressor host. Five inches of barrel still cycles standard 230-grain hardball reliably in a blowback action, and the shorter overall length makes single-handed manipulation around corners and inside doorways significantly easier. Velocity loss from a 7-inch to a 5-inch in .45 ACP is roughly 50-100 fps with standard pressure 230-grain loads, which is largely irrelevant terminally inside 25 yards.

The 7-inch is the right pick if you plan to shoot the Jawbone past 25 yards or run it suppressed as a primary range gun. Two extra inches of barrel buys roughly 100-200 fps depending on load, improves sight radius for the irons that aren't there (you'll want a red dot either way), and gives a little more real estate forward of the magwell for a support-hand grip. With a suppressor mounted, a 7-inch host puts the can closer to the shooter's line of sight, which makes the Jawbone feel less nose-heavy than the 5-inch with the same suppressor attached.

Both share the receiver, brace, ambi controls, dual charging options, full-length Picatinny rail, 4140 QPQ barrel, 5/8-24 threads, and 5-year limited warranty. The only meaningful difference is barrel length and the resulting overall length. Pick based on use case, not features.

The single highest-ROI upgrade for any new Jawbone 45 ACP owner is magazines. The factory ships one KCI 26-round stick, which is enough to leave the gun store but not enough to run a class, a defensive load-out, and a range bag at the same time. Plan on six to eight magazines minimum for any platform you intend to actually run hard. Buying mags is cheaper than buying a second gun, and for a Glock-pattern host, the supply chain is already everywhere.

Factory Glock 21 magazines hold 13 rounds and run cleanest in the platform. KCI 26-round and 30-round sticks are the budget high-capacity option. ETS makes a translucent 30-round Glock 21 mag for shooters who want to see remaining round count at a glance. For drum options, the SGM Tactical 50-round Glock 21 drum is the established workhorse. Verify drum function with this specific platform before relying on one for defense.

The Jawbone runs a full-length Picatinny rail, so any rifle red dot or pistol-caliber-friendly optic mounts directly. For a 5-inch braced gun used inside 25 yards, an enclosed micro red dot like the Holosun 510C or Aimpoint Duty RDS is the right answer: large window, eye-box forgiveness during awkward braced shooting positions, and weatherproof construction. For a 7-inch suppressor host stretched out to 50 yards, a 1x prism or compact LPVO with a true 1x first focal plane reticle gives the shooter a chance at hits past pistol distance. See our best red dot guide for ranked options across price tiers, or use the rifle builder to spec a complete Jawbone setup including optic, light, and suppressor.

At $599 MSRP and roughly $520 street, the Jawbone 45 ACP is the cheapest factory-threaded, optic-ready, Glock-mag-fed .45 braced pistol on the market. It will not out-shoot a CMMG Banshee or a B&T GHM45, and it does not pretend to. What it does is hit a price point that puts a .45 ACP suppressor host within reach of buyers who would otherwise be priced out of the segment entirely. Glock 21 magazine compatibility is the feature that makes this gun make sense: cheap mags, deep aftermarket, and a parts pipeline that already exists.

The 5-inch is the better buy for the home-defense and vehicle role. The 7-inch is the better buy for suppressor work and any shooting past 25 yards. Both ship with one KCI 26-round mag, both run the Ace of Brace paddle, and both are covered by the same 5-year limited warranty. Buy mags first, optic second, suppressor third.
