About this product
What is the GForce Arms RPX3C9 9mm 4″ FDE 15+1?
The GForce Arms RPX3C9 is a polymer-framed 9mm pistol built around Glock magazine compatibility and a flared magazine well. It combines a 4-inch barrel length with a 15+1 round capacity, making it a direct competitor to compact duty pistols like the Glock 19 Gen5. The Flat Dark Earth finish, fiber-optic front sight, and aggressive slide serrations position it as an affordable yet mechanically sound option for shooters who understand the importance of manual of arms standardization.
What is the GForce Arms RPX3C9 used for?
The RPX3C9 is designed primarily as an entry-level duty/defensive pistol and a training platform. Its 4-inch barrel strikes a practical balance between concealment and muzzle velocity retention, making it suitable for range drills and potential concealed carry after validation. The Glock-compatible magazine system allows shooters to leverage existing gear ecosystems, while the polymer frame keeps unloaded weight around 23 ounces for manageable all-day carry.
How does the GForce Arms RPX3C9 compare to the Stevens 334 Rifle?
The RPX3C9 serves a fundamentally different role than the Stevens 334 Rifle, which is a centerfire bolt-action platform for hunting and precision shooting. While the Stevens 334 in .308 Winchester excels at delivering accurate shots at 200+ yards with its 20-inch barrel, the RPX3C9 is optimized for rapid engagement at defensive distances under 25 meters. The pistol is better for close-quarters training and daily carry, whereas the rifle is superior for controlled hunting scenarios.
What does it weigh and what are the dimensions?
Unloaded weight is approximately 23 ounces (652 grams), with an overall length of 7.2 inches (183 mm) and height of 5 inches (127 mm) including the magazine. The 4-inch (102 mm) cold-hammer-forged barrel provides standard twist rates for 115-147 grain ammunition, while the grip circumference measures roughly 5.5 inches—comparable to a Gen3 Glock 19 frame. These dimensions place it squarely in the compact duty category, not subcompact.
Who is this NOT for?
This pistol is not for competitive shooters chasing sub-1.5-second split times or collectors seeking heirloom-grade fit and finish. The trigger break, while consistent, averages 5.5 pounds with noticeable take-up; competitors will prefer aftermarket options. The polymer frame lacks the aggressive stippling of higher-end duty guns, requiring aftermarket grip tape for high-sweat scenarios. If your primary use is suppressor or optics mounting, the lack of factory-cut slide options makes it inefficient.
What's in the box?
You receive the pistol, two 15-round steel-lined polymer magazines (or 10-round compliant versions depending on jurisdiction), a basic cable lock, and minimal paperwork. Unlike some competitors, no spare backstraps, sight adjustment tools, or cleaning kits are included—expect to source those separately. The magazines use standard Glock-style followers and springs, which are widely available for maintenance.
Is the GForce Arms RPX3C9 worth it at $272.99?
At $272.99, this pistol delivers tangible value as a functional training tool or backup defensive firearm. Compared to a $550 Glock 19 Gen5, you're accepting a simpler trigger system and less refined ergonomics for nearly 50% cost savings. If your budget demands a mechanically reliable 9mm with proven magazine compatibility—and you're willing to potentially upgrade sights or triggers later—this represents a sensible entry point. For all-weather duty use, consider saving for the proven track record of higher-tier brands.

Pros & cons
What works
- Glock magazine compatibility - leverages industry-standard 9mm magazine ecosystem
- 4-inch barrel delivers approximately 1100-1250 FPS with 115-grain ammunition
- Weighs 23 ounces unloaded - comparable to polymer-frame competition guns
- Includes two 15-round steel-lined magazines - most competitors ship only one
Trade-offs
- Trigger measures 5.5-pound break with 0.25-inch take-up - requires practice for precision shooting
- No optics-ready slide option - milling service adds $120-200 minimum
- Frame lacks stippling or aggressive texture - requires talon grips or tape for secure handling
- Limited aftermarket support for proprietary small parts compared to Glock or SIG

Frequently asked questions
- Is it compatible with standard Glock 19 magazines?
- Yes, the RPX3C9 accepts all double-stack 9mm Glock magazines including Gen3, Gen4, and Gen5 15-round and 17-round models. Tested compatibility extends to OEM, Magpul PMAG, and ETS clear versions without modification. The flared magazine well accommodates fast reloads with both 15-round and extended 33-round magazines.
- Does this pistol fit standard Glock 19 holsters?
- Most Kydex and polymer Glock 19 holsters will accommodate the RPX3C9's slide profile, but dimension variances may cause retention issues. The frame width measures 1.26 inches versus the Glock 19's 1.26 inches, but the slide serration pattern differs. We recommend testing in holsters like the Safariland 7378 or Vedder LightTuck before committing to modifications.
- Can I mount a red dot optic on this slide?
- No, the RPX3C9 slide is not factory-milled for optics mounting. You would need to send the slide to a machining service like Jagerwerks or ATEi for milling, adding $120-$200 plus coating costs. The slide thickness is sufficient for common footprints like RMR or Holosun 407C, but the rear sight system would need replacement.
- What is the shipping time for this firearm?
- Firearms ship within 2-3 business days to your selected FFL dealer after verification. Transit via FedEx or UPS typically adds 3-5 additional business days depending on location. All shipments require adult signature and FFL documentation exchange before release—budget 7-10 total days from order to pickup.
