The FN P90 and FN PS90 are both personal defense weapons (PDWs) renowned for their compact size, high capacity magazines, and unique bullpup design. While sharing a family resemblance, several key differences set them apart, impacting their suitability for various roles. This detailed comparison will clarify the distinctions between the P90 and PS90, helping you understand which weapon might be right for you – acknowledging, of course, that civilian access to these weapons is heavily regulated and may be unavailable in many jurisdictions.
Key Differences Between the P90 and PS90
The core difference lies in caliber: the P90 fires the 5.7x28mm cartridge, while the PS90 uses the same round but in a slightly reduced, .22-caliber form. This seemingly small change has significant repercussions on performance and application.
1. Caliber and Ballistics:
- P90 (5.7x28mm): This round is designed for superior penetration and stopping power compared to traditional pistol calibers. It's known for its flat trajectory, making it accurate at longer ranges, and its ability to penetrate body armor in certain situations. The higher velocity and heavier bullet contribute to its effectiveness.
- PS90 (.22LR): Utilizing .22 LR ammunition significantly reduces the cost per round and recoil. The PS90 also showcases reduced penetration capabilities in comparison to its larger caliber counterpart. The lower velocity and lighter bullet offer less stopping power at longer ranges. It is more suitable for training or smaller game.
2. Intended Use:
- P90: Primarily designed as a military and law enforcement weapon for close-quarters combat (CQB) and personal defense. Its high capacity magazine and potent round make it effective against multiple targets.
- PS90: Often positioned as a training weapon for P90 users, or a civilian option where legal restrictions limit access to the more powerful 5.7x28mm caliber. Its reduced recoil and lower cost of ammunition make it suitable for practice and recreational shooting.
3. Recoil and Handling:
- P90: While manageable, the P90's recoil is noticeably stronger than the PS90, owing to the more powerful cartridge.
- PS90: The .22 LR round produces considerably less recoil, making it easier to control, especially for novice shooters. This is a significant advantage for training purposes.
4. Penetration and Stopping Power:
- P90: The 5.7x28mm offers superior penetration and stopping power due to higher velocity and heavier projectile weight.
- PS90: Penetration and stopping power are significantly less than the P90, with the .22 LR round being less effective against hard targets or deeply penetrating barriers.
5. Ammunition Cost:
- P90: 5.7x28mm ammunition tends to be significantly more expensive than .22 LR ammunition.
- PS90: The readily available and relatively inexpensive .22 LR ammunition is a major advantage, making it cost-effective for training and practice.
Summary Table: P90 vs. PS90
| Feature | P90 (5.7x28mm) | PS90 (.22 LR) |
|---|---|---|
| Caliber | 5.7x28mm | .22 Long Rifle |
| Penetration | High | Low |
| Stopping Power | High | Low |
| Recoil | Moderate to High | Low |
| Ammunition Cost | High | Low |
| Intended Use | Military/LE; Close-Quarters Combat | Training; Recreational Shooting |
Choosing between the P90 and PS90 ultimately depends on individual needs and priorities. The P90 provides superior stopping power and penetration, ideal for military and law enforcement applications. The PS90 offers a more affordable, lower-recoil option well-suited for training and recreational purposes. Remember to always abide by local laws and regulations regarding firearm ownership and usage.
