The FN P90 has earned an almost cult-like following over the years. Between its unmistakable bullpup design, 5.7×28 chambering, and appearances in countless movies and video games, it's one of the most recognizable firearms on the market. While the civilian PS90 has always looked the part, many enthusiasts have wondered if there was a way to bring the shooting experience a little closer to what made the platform so iconic.
That's exactly what FN Specialties and Armory of Kings set out to accomplish with the XPRT 90.
After spending time with the XPRT 90, putting roughly 1,000 rounds through the system, and sitting down with its designer to discuss the development process, we came away impressed with what this trigger kit brings to the PS90 platform.

What Is the XPRT 90?
The XPRT 90 is a replacement trigger kit designed specifically for the FN PS90. Rather than simply replacing the factory trigger, the kit completely replaces several of the factory polymer fire control components with precision-machined 17-4 stainless steel parts.
The kit includes:
-6061 aluminum three-position selector
-17-4 stainless steel hammer
-17-4 stainless steel out-of-battery sear
-17-4 stainless steel reset component
The system offers standard semi-automatic operation while also incorporating a progressive forced-reset mechanism through its third selector position, maintaining one trigger pull for every round fired.
FN Specialties also includes an installation jig to simplify assembly of the trigger pack.
Range Performance
Once we got behind the gun, the first thing we noticed was just how natural the trigger felt after a short adjustment period.
Coming primarily from an AR background, the progressive trigger design took a few magazines to get accustomed to, but once we settled in, it became much more intuitive.
The PS90's greatest strength has always been its incredibly soft recoil, and the XPRT 90 complements that characteristic well.
To see just how manageable it was, we ran drills at 15 yards before backing up to 20 and 25 yards. At closer distances we were consistently able to keep the majority of our shots inside the A-zone.
Reliability
Throughout approximately 1,000 rounds of testing, reliability was good.
The only malfunctions we experienced occurred while using off-brand magazines. Once we switched back to factory FN PS90 magazines, we stopped having these issues.
Heat Considerations
One point FN Specialties emphasizes is heat management.
Because the PS90's barrel and breech block assembly are largely enclosed within the stock, airflow is limited. As a result, heat builds more quickly during sustained firing.
For that reason, FN Specialties recommends limiting extended strings of rapid fire to no more than two magazines before allowing the firearm to cool. Excessive heat buildup can lead to reliability issues and, in extreme cases, potentially damage the firearm.
Talking with the Designer
One of the highlights of this project was the opportunity to sit down with Dorin from FN Specialties and Armory of Kings.
During our interview, Dorin discussed the years of development that went into the XPRT 90, explaining that the design had already surpassed thousands of rounds of internal testing before its release. Since launch, additional testing by industry partners has continued without any unusual wear patterns or premature component failures.
We also discussed several practical considerations for owners, including suppressor compatibility, chamber cleanliness, dry-fire recommendations, and the reasoning behind replacing the factory polymer hammer with a heat-treated and nitrided 17-4 stainless steel component.
The Comparison Everyone Wants
Naturally, one question kept coming up throughout this review:
How close does it get?
To answer that, the team at Mister Guns in Plano generously allowed us to spend time with a P90 so we could compare the two platforms side by side.
As expected, there is still a noticeable difference between the two.
The P90 remains its own experience, but after shooting both back-to-back, we were genuinely impressed with just how close the XPRT 90 gets while still remaining a semi-automatic trigger system.
Is It Worth It?
With an MSRP between $420 and $450, the XPRT 90 certainly isn't an inexpensive upgrade. In our opinion, if there's any gun where a trigger like this makes sense, it's the PS90. The platform's light recoil, controllability, and overall shooting characteristics make it an excellent fit for what the XPRT 90 was designed to accomplish. After roughly 1,000 rounds on the range, we walked away impressed by both its performance and the engineering behind it. While it carries a premium price tag, it also offers a capability that simply wasn't available to PS90 owners before.
If you're already invested in the PS90 platform and are looking for something that genuinely changes the shooting experience, the XPRT 90 is certainly worth taking a closer look at.
