FAQs

Can I use standard pistol ammunition in the FN P90?

No. The FN P90 is chambered exclusively for 5.7x28mm ammunition, which is not interchangeable with common pistol calibers.

What is the magazine capacity of the FN P90?

The FN P90 uses a unique top-mounted magazine holding 50 rounds of 5.7x28mm ammunition.

How does the bullpup design benefit the FN P90?

The bullpup layout places the action behind the trigger, reducing overall length while keeping barrel length optimal for accuracy.
