Features Comparison: SIG P320 VS M&P 2.0
1. Trigger Quality
SIG P320
The trigger on the SIG P320 is genuinely impressive. Out of the box, it offers a smooth and consistent pull, weighing 5.5 to 7.5 lbs.
The metal construction adds to its durability and provides a solid, tactile response. The break was clean during testing, and the reset was audible and tactile, enhancing the shooting experience.
M&P 2.0
The M&P 2.0’s trigger, in contrast, feels a bit lackluster. It’s a polymer trigger with an approximate pull of 5 lbs.
However, during field tests, I found the trigger pull somewhat inconsistent. The reset was not as distinct as I’d prefer, which could affect rapid follow-up shots.
Winner
Compared to the M&P 2.0, the SIG P320 is the clear winner in trigger quality. Its metal construction and consistent performance provide a superior shooting experience.
2. Front Serrations and Slide Operation
SIG P320
The front serrations on the SIG P320 are well-designed and practical. From day one, these serrations have provided a solid grip, making slide manipulation easy and reliable.
These serrations proved their worth in the field, especially in rapid fire or stressful scenarios.
M&P 2.0
The M&P 2.0’s front serrations are somewhat disappointing. Many of the 2.0 models have small serrations that offer limited utility.
I found them to be less effective during testing, particularly when operating the slide quickly or with wet hands.
Winner
The SIG P320, compared to the M&P 2.0, excels with its practical and well-designed front serrations. This feature significantly enhances the overall functionality of the firearm.
3. Ergonomics and Handling
SIG P320
The SIG P320 shines in its ergonomic design. Thanks to its interchangeable polymer grips, the grip is comfortable and offers a secure hold.
This translated to better control and accuracy in the field, especially during rapid firing sequences.
M&P 2.0
The M&P 2.0 also boasts impressive ergonomics. Its grip is designed to fit a wide range of hand sizes comfortably. During testing, the grip felt natural and provided a solid hold, although it was slightly less comfortable than the P320 for extended shooting sessions.
Winner
Comparing the two, the SIG P320 edges out slightly with its superior grip design and overall handling comfort.
