Got mine delivered today. Like. A lot.
I was an early X5 adopter and I need a small grip (I have short stubby fingers). I have been pissed at Sig for a few years now for their "modular" handgun that comes with one grip size in the X-series format (which, despite the great quality of the X5, drove me to CZ). I've been using a standard 320 small grip which I never really liked but at least it fit my hand.
Comparison to standard 320 small grip:
- Size is comparable to Sig small.
- Wilson's is squarer (more like X-series).
- Grip angle is slightly more pronounced.
- Front strap is awesome. Back strap is ok. Sides are not grippy (I'll want grip tape).
- Beaver tail is slightly higher.
- Thumb indent rides lower providing easier access to the mag release.
- Undercut trigger guard provides much better middle finger grip.
- Grip length is about the same, but the Wilson has a flare at the magwell that makes the grip more secure.
There looks to be tungsten slots from the top, but it's a custom system and not compatible with Sig's X-series modules at all.
An easy and welcome upgrade choice for me. YMMV.
