Caracal CMP9 and CMP9K: MP5 Magazine Compatibility
Caracal USA displayed the CMP9 and CMP9K at SHOT Show 2026 in Booth #10334. Both models are 9x19mm NATO-chambered pistols accepting HK MP5-type 30-round magazines. The platforms use advanced blowback operation and feature cold hammer-forged barrels with 1:10-inch twist rates.
| Model | Barrel | Overall Length | Weight | MSRP |
|---|---|---|---|---|
| CMP9 | 9" | 17.1" | - | $1,833 |
| CMP9K | 6" | 14" | 4.5 lbs | $1,833 |
Both platforms feature 7075-T6 aluminum receivers with machined 1913 Picatinny rails, M-LOK handguards, and threaded muzzles (2/28 pitch). The top rail accepts optics, while ambidextrous controls and charging handles accommodate both left and right-handed shooters. AR/M4-compatible pistol grips allow grip module swaps.
Both models are now available through authorized dealers, with units shipping since November 2025.
B&T APC9SD and KH9B: Swiss Precision Systems
B&T showcased the APC9SD and KH9B at SHOT Show 2026. Classic Firearms conducted an interview with B&T representatives covering both platforms. The APC9SD is an existing product line featuring an integrally suppressed barrel optimized for subsonic 9mm ammunition, while the KH9B represents a compact variant in the separate KH9-series lineup.
The APC9 platform uses a hydraulic buffer system to reduce felt recoil and features a closed-bolt blowback operation. The SD variant integrates the suppressor into the barrel assembly, eliminating the need for separate suppressor mounting. B&T also displayed their latest suppressor designs alongside the PCC platforms.
Pricing and availability details for the APC9SD and KH9B were not provided at the show. B&T representatives stated that updated information would be released through dealer channels.

PSA AXR PDW: Modular Fire Control 9mm Platform
Palmetto State Armory introduced the AXR PDW as part of their modular AXR Series ecosystem at SHOT Show 2026. The platform uses the same serialized Modular Fire Control (MFC) as the AXR handguns, allowing users to swap between PDW and pistol configurations without additional paperwork.
The AXR PDW accepts either Glock magazines or Sig P320 magazines depending on the selected grip module. The platform represents PSA's evolution of the previous X9 concept, integrating it into the AXR modular ecosystem. The PDW format provides a quick-deploy 9mm platform while maintaining compatibility with existing AXR components.
Additional details on barrel length, overall dimensions, and weight were not disclosed at the show. PSA stated that full specifications and pricing would be announced closer to the release date.
EDDY Harness by Triangle WRS: Purpose-Built PCC Concealment
The Executive Detail Detachable Yoke (EDDY) harness by Triangle WRS was the most-scanned product during Day 2 of SHOT Show 2026. The system is designed specifically for concealed carry of pistol caliber submachine guns under clothing. The hands-free design positions the firearm close to the body and reduces fatigue during extended carry periods.
The harness accommodates various PCC and subgun platforms through adjustable retention systems. The under-clothing design allows discrete carry while maintaining quick access. Weight distribution across the shoulders and torso reduces pressure points compared to sling-based carry methods.
Pricing, material specifications, and platform compatibility details were not disclosed at the show. The high scan count indicates significant interest in purpose-built PCC concealment solutions.

The End of the AR-9 Era
SHOT Show 2026 marks the transition away from simple blowback AR-9 platforms toward advanced operating systems. Manufacturers are adopting modern designs that move beyond the basic blowback systems that dominated the market in previous years.
MP5-compatible magazine systems are gaining traction with Caracal's entry into the market. The availability of surplus and aftermarket MP5 magazines provides an established ecosystem for new platforms. Manufacturers are leveraging this existing infrastructure rather than developing proprietary magazine systems.
Modular fire control systems like PSA's AXR platform allow users to swap between pistol and PDW configurations using a single serialized component. This approach reduces the barrier to entry for multiple configurations and simplifies ATF compliance.
The emergence of purpose-built concealment gear like the EDDY harness by Triangle WRS indicates growing interest in discrete PCC carry. The high scan count suggests demand for solutions beyond traditional sling-based carry methods.
Suppressed variants from B&T showcase the integration of sound suppression into PCC platforms. Integrally suppressed designs eliminate the need for separate suppressor mounting and simplify the overall package for users requiring quiet operation.
