Features Comparison: SIG P320 VS SIG P229
1. Action Type and Trigger Pull
SIG P320
The P320, with its striker-fired DAO (Double Action Only) mechanism, offers a smooth and consistent trigger pull, ranging from 5.5 to 7.5 lbs.
This led to a predictable and steady shot during my testing, reducing the chances of jerking the trigger.
SIG P229
The P229, featuring a DA/SA (Double Action/Single Action) mechanism, presents a different experience.
The initial double-action pull is heavier at 10 lbs, transitioning to a lighter 4.4 lbs in single-action. This variation demands more adaptability but can be advantageous for safety and control.
Winner
Comparing these features, the P320 stands out for its consistency and ease of use, especially for beginners. However, experienced shooters might appreciate the P229’s DA/SA mechanism for its added safety and control elements.
So, compared to the P229, the P320 wins for simplicity and predictability in the trigger pull.
2. Weight and Handling
SIG P320
The P320 is noticeably lighter at 26 oz with the magazine. This makes it more comfortable for extended periods of shooting and carrying. Its handling is straightforward, and its light weight contributes to quicker maneuverability.
SIG P229
The P229, being heavier at 32 oz with the magazine, offers a more substantial feel. As I noticed, this extra weight helps absorb more recoil, making shooting smoother and potentially more accurate.
Winner
For weight and handling, it’s a bit of a toss-up. The P320, compared to the P229, is easier to handle due to its lighter weight, making it ideal for longer periods of carry and use.
However, the P229’s heft can be a boon for recoil management and stability. So, it depends on personal preference.
3. Modularity and Maintenance
SIG P320
The P320 shines in modularity. It can be disassembled without tools and allows for easy customization with various grips and frames.
Maintenance-wise, it’s a breeze to clean and reassemble, making it highly user-friendly.
SIG P229
The P229, while robust, lacks the modularity of the P320. Its traditional design means less flexibility in customization.
Maintenance is straightforward, but not as simple as the P320, especially when it comes to disassembly and reassembly.
Winner
In terms of modularity and ease of maintenance, the P320 clearly has the upper hand compared to the P229. Its tool-free disassembly and customization options make it a more adaptable and user-friendly choice.
4. Ergonomics and Grip
SIG P320
The P320 boasts a remarkably comfortable grip, thanks to its interchangeable polymer grips. Its ergonomic design fits naturally in the hand, making it easy to handle, especially during extended shooting sessions.
The balance feels just right, enhancing shooting accuracy.
SIG P229
The P229, with its black polymer factory grips, offers a solid and secure feel. However, it’s slightly less ergonomic compared to the P320, primarily due to its heavier frame. The grip is sturdy but might not be as comfortable for all hand sizes.
Winner
When it comes to ergonomics and grip, the P320 takes the lead compared to the P229. Its modular grip system and lighter frame provide a more comfortable and adaptable handling experience.
