Questions & Answers
I'm Right Handed. What side should I pick for my Thumb Rest? I will need the Thumb Rest on the left side of my gun. Manufacturer Answer

Does this work with Macro magazines? Manufacturer Answer

The Macro magazines that are sold separately come with three different basepads. The mid-length is a perfect fit for this grip. The magazines that come standard with the pistol only come with a short baseplate, so you might need a modified baseplate to cover the extended magazine.

In the picture it showed the 1913 rail on the front of the grip. What arrived is not that. Quite disappointing to have to wait another three weeks for a return to get the right one.
