i think you will like it.... the grip is imo perfect as is..... no aftermarket add ons for this one. out of the box perfection.
Not in the market for anything like a service pistol right now, but I have to admit that "Sig, the next generation" looks mighty comfy and efficient.
I've come to the conclusion that ergonomics is everything. The worse the fit, the more "pre-stress" that gets pre-loaded into your hand and arm before even firing the first shot.
In my case, if the handgun has swappable parts to redo grip shape, I get consistently better (and more comfortable) shooting with the grips reduced as much as possible.
