Most Helpful Positive Review Two tone Xmacro
I already had the bronze barrel on my Radian comp along with a black Radian magwell/backstrap on another pistol. Swithched things around after picking this up making one Xmacro a full Radian two tone and my other Xmacro peanut butter another two-tone with the black backstrap/magwell. This backstrap fits my hand perfectly and allows my grid to be much better than the stock grips.

Radian Rec

This made my x macro grip feel so much better. A slight bit more grip to hold onto and help to eliminate the feeling of the gun being top heavy. Looks great too!

  • None
