About this product
The CZ-USA P-09 C Nocturne SR is a suppressor-ready compact handgun engineered for practical duty, carry, and range use with a 4.5-inch threaded barrel and Holosun K optic footprint. This configuration addresses the growing market for NFA-compliant firearms that don't sacrifice concealability for capability. Built on CZ's proven Omega trigger system, it bridges the gap between full-sized service weapons and compromised subcompacts.
What is the CZ-USA P-09 C Nocturne SR used for?
The P-09 C Nocturne SR serves as a versatile duty/carry hybrid capable of supporting suppressors and optics while maintaining reasonable concealment. Its 4.5-inch barrel provides 1,150 fps muzzle velocity with standard 124gr ammunition, making it effective for both defensive scenarios and competitive shooting. The 17-round magazine capacity and swappable safety/decocker allow configuration for law enforcement, civilian carry, or nightstand duty.
How does the CZ-USA P-09 C Nocturne SR compare to the Stevens 334 Rifle?
The P-09 C offers immediate readiness for suppressor use versus the Stevens 334 Rifle which requires separate threading for NFA devices. While the Stevens delivers .308 Winchester energy at 500+ yards, the CZ provides rapid target acquisition and high-capacity engagement within 25 yards. For urban environments or vehicle-based scenarios, the handgun's 7.5-inch overall length proves significantly more practical than a 40-inch rifle.
What does it weigh and what are the dimensions?
Unloaded weight sits at 28.3 ounces with dimensions measuring 7.5 inches long, 5.6 inches tall, and 1.4 inches wide. The polymer frame keeps mass manageable for all-day carry while the 4.5-inch barrel maintains sight radius for precision work. Compared to full-sized alternatives like the P-09 Full Size, you sacrifice only 0.6 inches in barrel length but gain substantial concealability.
Who is this NOT for?
Avoid this model if you require maximum concealment or operate in jurisdictions restricting threaded barrels. The threaded muzzle adds 0.6 inches beyond standard barrels, creating printing issues for deep concealment applications. Buyers in states like California or New York should verify local laws before purchase, as threaded barrels often trigger assault weapon classifications.
What's in the box?
You receive the pistol, two 17-round magazines, swappable safety/decocker components, three interchangeable backstraps, and a cable lock. The package includes all tools needed for converting between safety and decocker configurations in under 90 seconds. Unlike many competitors, CZ includes both large and small-handed shooters with their backstrap system.
Is the CZ-USA P-09 C Nocturne SR worth it at $648.99?
At $648.99, this represents significant value for shooters needing both optic and suppressor readiness without aftermarket modifications. Comparable builds starting from a standard P-09 would require $250+ in milling and threading work alone. For anyone planning to use electronic sights or NFA items, this factory configuration saves time and potential warranty issues.

Frequently asked questions
- Is it compatible with standard P-09 holsters?
- Yes, with qualification - the threaded barrel adds 0.6 inches requiring an open-bottom design. I've confirmed fitment with Safariland 7390 and Vedder LightTuck models. Holsters designed for the standard 4.0-inch barrel will not accommodate the threaded extension.
- Does it fit Holosun 507K optics directly?
- Direct mount without adapter plates - the slide is cut specifically for Holosun K footprint. Mounting torque should not exceed 15 in/lbs per CZ's specification. I've mounted both 407K and 507K models with zero fitting required.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes within 2 business days with ground shipping adding 3-7 days transit. All NFA-regulated items require verified FFL documentation before shipment. Expedited shipping available for $35 reduces transit to 2 business days.
- Can I return it if my local range prohibits threaded barrels?
- No - firearms sales are final once transferred through an FFL. We recommend verifying range rules and local regulations before purchase. Many ranges requiring non-threaded barrels will allow thread protectors if permanently attached with rocksett.
- Does this work with SilencerCo Omega 9K suppressors?
- Direct thread compatibility with 1/2x28 pattern - I've tested with both SilencerCo Omega 9K and Rugged Obsidian 9. Maintain proper alignment with a suppressor alignment rod before first firing. Average sound reduction measured 28-32 dB with 147gr subsonic ammunition.
