Most Helpful Negative Review P365 Radian Backstrap & Magwell

Radian Magwell-Backstrap Combo

by Levon, Verified Owner from IL, United States Written on October 17, 2026

These are very well made and add an aggressive look to the grip. Fit and finish are excellent. I added these to a Coyote polymer grip and the look is amazing. The backstrap is sized correctly to give a better fit to the hand and the pattern has a solid feel in your palm.

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:

Looks

Cons:

None

Best Used for:

Larping
