Most Helpful Positive Review Improved grip fit
I run a small grip module on all of my P320's. Personalization of the grip size improves handling and accuracy. The oem medium grip module is sufficient, however, with the ability to achieve a more personal fit, confidence in handling the weapon will also improve.

Smaller Size grip fits my hand the best.

by 357, Verified Owner from AL, United States Written on April 11, 2025
The size of the small module allows you to get a better grip than the medium size the M17 model comes with. The FCU fits tight with no loose movement to the FCU or slide.
I would recommend if you have medium to smaller size hands.
Pros:
  • Good fitment
Cons:
  • None
Best Used for:
  • Smaller size hands
Would recommend: Yes

The grip module was on back order for a few months, but definitely saved some money. It was a quick and easy process to switch the grips.

P320 Coyote Grip Module w/ Safety (Small)

by EDNEL, Verified Owner from MA, United States Written on October 29, 2023
The SIG P320 Grip Module w/ Manual Safety (small circumference) is a great addition to my M18 allowing for a better grip for my size hand. It is easy to replace and was completed in minutes. Being a SIG product for the modular P320 system, I would highly recommend this to anyone looking for a slightly smaller grip than the medium one that ships with the pistol.
Pros:
  • Great Fit
  • Ease of use / install
Cons:
  • None
Best Used for:
  • direct replacement
Would recommend: Yes

This should be the default size out of the box.

by AxG, Verified Owner from TX, United States Written on July 27, 2021
Ordered small grip size. Fits much better than the medium. The small sized grip module also has the net effect of having an longer beaver tail that enables a more secure grip. For reference glove size is large.
Would recommend: Yes

Cons:
  • None

Great Gift

by RDB, from WA, United States Written on July 28, 2020
Perfect fit for a friend who just purchased an M18 but wanted the look of the black frame with brown slide. Goes great with a FDE streamlight HL-1. Couldn’t be happier. Highly recommended. Have also purchased the Xcarry got myself and it shipped in a timely manner. OP has a lot of product that you can’t always get anywhere else. Thanks!
Pros:
  • Fit and finish
Cons:
  • None
Best Used for:
  • M18
