Features Comparison: SIG P320 X-5 Legion VS SIG P320 X5
1. Frame and Handling
SIG P320 X-5 Legion
The SIG P320 X-5 Legion’s frame is a standout, primarily due to its tungsten-infused grip module, significantly increasing the weight to about 43.5 ounces.
This substantial heft is a key factor in its performance. In my extensive field testing, I noticed that the added weight remarkably reduced muzzle flip. This characteristic is crucial for maintaining steady aim during rapid fire sequences.
The balance achieved through this heavier frame is exceptional, providing a solid, reassuring feel in hand, which is essential for precision shooting.
SIG P320 X5
Comparatively, the standard SIG P320 X5, with a weight of 35.5 ounces, offers a different handling experience. Its lighter frame enhances maneuverability, making it potentially more suitable for shooters who prefer a lighter firearm.
However, during rigorous testing sessions, I observed that this reduction in weight slightly increases recoil and muzzle movement. This aspect becomes more noticeable during continuous, rapid fire.
While the X5 remains a formidable firearm, it doesn’t quite reach the stability levels of the Legion, especially in scenarios demanding quick, successive shots.
Winner
After thorough evaluation, it’s clear that in terms of frame and handling, the SIG P320 X-5 Legion surpasses its counterpart.
The tungsten-infused frame not only contributes to a remarkable reduction in muzzle flip but also ensures superior stability and flat shooting dynamics.
This makes it an ideal choice for shooters who value these traits in their firearms, offering a distinct advantage over the standard X5 in high-paced shooting scenarios.
2. Sights
SIG P320 X-5 Legion
The X-Five Legion’s sights closely resemble those of the standard X5, with an important distinction in the optic mount.
The Legion is engineered for a Romeo 1 Pro optic, featuring a robust and durable aluminum housing. This design choice significantly affects field performance.
During practical shooting tests, I found this mount provided a more secure and stable platform for optics. This enhancement is not just about accuracy; it also instills greater confidence in the shooter. The precision and stability offered by this mount are evident in scenarios requiring quick target acquisition and consistent accuracy.
SIG P320 X5
The standard X5, equipped with a Romeo 1 optic mount and a magnesium plate, performs admirably. The sights are precise and facilitate easy alignment.
However, when subjected to comparative testing, the magnesium plate’s sturdiness doesn’t quite match the Legion’s aluminum housing.
This difference, though subtle, is noticeable in demanding shooting conditions where optimal stability of the optic mount can influence shot accuracy and consistency.
Winner
Considering the critical role of optics in precision shooting, the SIG P320 X-5 Legion edges out its rival in the sights category.
The aluminum housing for its optic mounts provides a more stable, reliable platform for precision aiming. Compared to the X5’s magnesium plate, the Legion’s mount demonstrates superior robustness and stability, making it the preferred choice for precision-focused shooters.
3. Trigger
SIG P320 X-5 Legion
The trigger mechanism of the X-Five Legion is an exemplary feature, designed not just for aesthetic appeal but for enhanced functionality.
The skeletonization of the trigger is a thoughtful design choice, resulting in a lighter and more distinct trigger pull. My hands-on experience with this trigger in various shooting drills revealed a marked improvement in rapid fire capabilities.
The trigger offers a crisp break and an exceptionally short reset, which significantly reduces the effort required for successive shots. This design is particularly advantageous in scenarios where quick, precise shots are paramount.
SIG P320 X5
The trigger of the standard X5, while well-crafted and delivering a reliable 5-pound pull, lacks the nuanced refinements of the Legion’s trigger.
In side-by-side testing, the X5’s trigger, though proficient, had a less distinct break and a slightly longer reset. This difference, while subtle, affects the speed and precision of follow-up shots, particularly in rapid firing sequences.
Winner
In the realm of trigger performance, the SIG P320 X-5 Legion clearly outperforms its counterpart. Its lighter, more responsive trigger mechanism provides a significant edge, particularly in rapid firing and precision shooting scenarios.
The distinct, crisp break and short reset of the Legion’s trigger allow for quicker, more accurate follow-up shots, establishing it as the superior choice in this category, especially when compared directly to the standard X5.
4. Ergonomics and Grip
SIG P320 X-5 Legion
The X-5 Legion’s ergonomics are enhanced by its tungsten-infused grip module, offering a robust and comfortable hold.
During my field tests, I found this grip provides superior control and stability, particularly under rapid fire conditions. The texture and shape of the grip are well thought out, allowing for a secure and natural hand position, which is crucial for maintaining accuracy over extended shooting sessions.
SIG P320 X5
The standard X5, with its polymer-frame construction, offers a lighter and somewhat more flexible grip. In my experience, this grip is comfortable and provides adequate control, especially for shooters preferring a lighter touch.
However, it doesn’t quite match the Legion in terms of the sheer stability and control offered by the heavier and more substantial grip.
Winner
The SIG P320 X-5 Legion excels in ergonomics and grip compared to the standard X5. Its heavier, tungsten-infused grip module provides a significant advantage in terms of control and stability, particularly in high-pressure shooting scenarios.
This feature makes it the preferred choice for shooters who prioritize a firm and stable grip in their firearms.
