Key Features
- Compact Bullpup Design: The action is housed behind the trigger, giving you a full 16-inch barrel in an overall length of just 26.2 inches. That’s shorter than most submachine guns.
- 5.7x28mm Chambering: This low-recoil, high-velocity round offers excellent penetration against soft armor and minimal over-penetration risk in home defense scenarios compared to traditional rifle calibers.
- Ambidextrous Controls: Fully ambidextrous safety, magazine release, and charging handles make it adaptable for any shooter. The unique top-mounted magazine feeds reliably and keeps the profile slim.
- Integrated Optics Rail: The receiver comes with a full-length MIL-STD-1913 Picatinny rail, ready for your choice of red dot, holographic sight, or magnified optic. It’s drop-in ready for popular optics like the Trijicon RMR or Vortex Sparc Solar.

It’s ideal for the home defender who needs a compact, low-recoil weapon that’s easy for other household members to use effectively.

The 26.2-inch overall length makes it exceptionally easy to maneuver in tight spaces like hallways or vehicles.
Pros & Cons
Pros: Unmatched compactness for its barrel length. Exceptionally soft recoil impulse allows for rapid, accurate follow-up shots. The 5.7x28mm round offers a compelling balance of penetration and safety in structured environments. Ambidextrous from the factory. Renowned FN reliability.
Cons: Ammunition cost is higher than common calibers like 9mm or .223. Aftermarket support, while growing, isn’t as vast as for the AR-15 platform. The proprietary magazine design means you’ll need specific PS-90 mags, though they are readily available.
Frequently Asked Questions
Q: Is the 10-round magazine the only option?
A: The carbine ships with one 10-round magazine, which is the standard compliant configuration. Factory 30-round magazines are available separately and can be easily converted to 10-round limited capacity for compliance, depending on your local laws. This model is available at firearms-missouri.com for Missouri residents and nationwide where legal.
Q: Can you mount a sling on the PS-90?
A: Absolutely. The stock has integrated sling mounting points, and the design naturally lends itself to both single-point and two-point sling attachment. Adding a quality two-point sling from a brand like Blue Force Gear or Magpul dramatically improves weapon retention and handling during movement.
Q: How does the 5.7x28mm perform for home defense?
A: Here’s the thing—the 5.7x28mm is a high-velocity, small-caliber round. It tends to fragment or yaw rapidly upon hitting drywall, which reduces the risk of over-penetration through multiple interior walls compared to heavier, slower pistol rounds or rifle cartridges. Combined with the PS-90’s low recoil and high capacity, it creates a very effective and responsible home defense system.
