Most Helpful Positive Review Expensive but well worth it
I have large hands being 6'10" and the standard macro grip, while far superior to the standard 365 was still uncomfortable. This backstrap and magwell makes this small edc feel and control like a full framed gun thanks to the pinky groove and aggressive checkering. Machine quality is also absolutely...

Most Helpful Negative Review P365 Radian Backstrap & Magwell
Looks better than it feels. Doesn't feel bad, but it features some sharp edges that are not the most comfortable in the hand. Solid construction and easy installation.

It’s okay meh at best

by Squib, Verified Owner from CA, United States Written on April 14, 2026
It looks coo It definitely prints more If you edc To me, the benefits don’t outweigh the negatives The backstrap isn’t bigger than the large insert that comes with the factory like I was hoping The mag well and pinky ledge is the most noticeable enhancement but for me Its the biggest downside with printing if you edc In my opinion it’s overpriced and not worth it
Pros:

Cons:
  • None

A Must for X-Macro

by Stake, Verified Owner from MI, United States Written on March 31, 2026
Adds improved grip/feel to X-Macro grip module and has a nice aggressive look. The weight from the magwell/backstrap makes it feel much more balanced and locks you in high and tight to the beaver tail. Magwell gives an additional point in contact at the bottom to manage recoil. 100% recommended getting the radian baseplates but OEM 17 sig mags fit in magwell. Magpul 17 round mags will not fit in magwell without significant modification.
Pros:
  • Improved accuracy and grip
Cons:
  • None
Best Used for:
  • EDC
Would recommend: Yes

Excellent feel and look!

by SK31, Verified Owner from NC, United States Written on March 10, 2026
Really happy with the Radian backstrap/magwell! The fit is spot on and it looks great on an Armory Craft lower. It feels comfortable in the hand and made a big difference in grip, way more control than before. Definitely a solid upgrade. Quality is top notch and it just feels right once installed. Highly recommend!
