Kicking around the idea of adding a slip in frame weight to my X Carry frame. Do ya'll think it's worth it as far as reoil reduction? I understand the concept but not sure if translates to recoil reduction when the weight is in the rear. Do ya'll feel the heavier weight slows down when you drive the gun or on presentation?
Most of the P320 grip modules have provision to add weights. The weights affect balance as well as mass.
Most P320 grip modules are very light.
Sig also offers the TXG frame, which is the "tungsten infused" grip module used on the P320 legion. The grip module is heavy. It also has provision for a grip weight, and a mag well funnel, which adds more weight. I have several of those and like them. I run the module with the grip weight and the funnel.
