7 Shocking Ways The P320 XTen Endure Comp Tames The 10mm Beast
The SIG SAUER P320-XTEN Endure Comp has officially landed, redefining what a polymer-framed 10mm Auto pistol can be. As of December 25, 2025, this newest offering from SIG Custom Works' Endure Series is generating massive buzz among enthusiasts and backcountry adventurers alike, promising a high-powered handgun with unprecedented shootability and recoil management. This deep dive explores the core features that make the Endure Comp a game-changer for anyone seeking a powerful, yet controllable, sidearm for the wilderness or competition.
The original P320-XTEN was already a strong contender in the 10mm market, but the introduction of the integrally compensated slide on the Endure Comp model elevates its performance significantly. Designed to withstand the toughest outdoor conditions, this pistol is not just a tool; it's a testament to modern firearm engineering, blending raw stopping power with ergonomic excellence to deliver a flat-shooting, accurate experience.

The combination of a shorter barrel and the integrated compensator is a deliberate design choice, aiming to keep the overall package manageable while significantly reducing the felt recoil of the powerful 10mm cartridge. This makes the pistol a viable option for users who previously found the 10mm too harsh for rapid follow-up shots.
How the Integral Compensator Reimagines 10mm Recoil Management
The most significant innovation in the P320-XTEN Endure Comp is the integrally compensated slide. Unlike threaded barrels and add-on compensators, which increase the overall length and complexity of the firearm, the Endure Comp features a port cut directly into the slide and a shorter 3.8-inch barrel. This design offers several critical advantages for a high-pressure round like the 10mm Auto.
1. Superior Recoil Reduction and Muzzle Flip
The compensator directs propellant gases upward and slightly rearward as the bullet exits the muzzle. This force acts as a counter-lever, pushing the muzzle down and forward, dramatically reducing muzzle flip and felt recoil. This makes the pistol "flat" to shoot, allowing for faster and more accurate follow-up shots—a crucial factor when dealing with dangerous game or in dynamic competition scenarios.
2. Optimized Barrel Length for Compensation
The 3.8-inch barrel is shorter than the standard 5-inch XTen barrel. This allows the compensator to be integrated without making the pistol excessively long. The shorter barrel also means the bullet exits the barrel sooner, ensuring there is still sufficient gas pressure to effectively operate the compensation port, maintaining the high velocity and energy the 10mm round is known for.
3. Enhanced Controllability and Shootability
Early reviews and user feedback consistently highlight the Endure Comp’s shootability. One user noted it is "Loud, flat, and accurate," even comparing it favorably to other 10mm pistols, including the popular Glock 20. The ability to control the potent 10mm round with a polymer-framed, striker-fired pistol is a major selling point and a primary reason for the pistol's high praise.
Designed for Adventure: The Endure Series Difference
The "Endure" designation is not just a marketing term; it signifies a commitment to rugged durability and user-focused features, making this pistol ideal for backcountry carry, hunting, and survival. The SIG Custom Works shop built the Endure Comp to be a reliable partner in the most extreme conditions.
The X-Series Fire Control Unit and Flat Trigger
At the heart of the pistol is the legendary P320 Fire Control Unit (FCU), which is housed within the XTen grip module. The pistol features the X Flat Trigger, a design favored by competitive and tactical shooters. This trigger provides a clean, crisp 90-degree break and a short, positive reset, which enhances precision and speed during rapid fire sequences.
Ready for Optics and Low-Light Conditions
For modern shooters, an optics-ready slide is essential. The Endure Comp features a slide cut with the PRO footprint, allowing for direct mounting of popular red dot sights like the SIG SAUER Romeo2 or EOTech EFLX. This, combined with the standard XRAY3 Day/Night Sights, ensures that the shooter has a reliable sight picture in any lighting condition, from bright daylight to deep twilight.
The Power of 10mm Auto for Bear Defense
The 10mm Auto caliber has long been favored for bear defense and as a hard-hitting hunting round. The Endure Comp provides 15+1 rounds of this powerful ammunition, offering a superior capacity compared to many traditional 10mm handguns. The enhanced controllability of the compensated design means a user is more likely to land multiple, accurate shots under duress, maximizing the effectiveness of the 10mm round in a self-defense scenario against large predators.
Final Verdict: Is the P320 XTen Endure Comp the Best Striker-Fired 10mm?
The SIG SAUER P320-XTEN Endure Comp is more than just an iteration; it's a significant upgrade that addresses the primary drawback of the 10mm Auto: its sharp recoil. By integrating the compensator, SIG Custom Works has created a pistol that is flat-shooting, accurate, and incredibly durable, making it a top-tier choice for a variety of demanding applications.
With its high capacity, optics-ready slide, and rugged Endure Series finish, the P320-XTEN Endure Comp stands out in a crowded market. Whether you are a competitive shooter looking for an edge, a hunter needing a powerful sidearm, or an outdoor enthusiast seeking reliable bear defense, this pistol offers a unique blend of power and control. If you are in the market for a polymer 10mm handgun, the Endure Comp should be at the very top of your list for its innovative design and proven performance. It truly sets a new standard for the modern, high-power striker-fired pistol.
