Questions & Answers
Am I right that this will not fit on a P365 X frame- just the XMacro frame, And, if so, will you be making one for the X frame?

Unlikely, as the XMacro frame has the ability to change its back-strap, this is a replacement for that portion. The smaller XL/X frames don’t have interchangeable back-straps so I do not see them making one for those frames.

Is there a small, medium, and large size backstrap?

No there is not, not too sure why it says that on OPs site but if you go to radian it shows a guide and the sku number on the site is H0014 which is the same here as well

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 aggress...

Helpful Positive Review Best Sig Upgrade by ElRey762, Verified Owner, October 13, 2024
Takes the factory grip to another level. Pairs well with the Radian BasePads. Gives full grip and the Magwell gives excellent feedback lip.

Helpful Positive Review Nicely made piece. by KW, Verified Owner, May 1, 2024
I like Radian stuff, they are a local company to me so I wanted to try it out. It's a nicely made piece, but for me the magwell wasn't big enough. I switched back to the NDZ magwell on the factory backstrap because it locks your hand onto the grip be...
