Various Grip Sizes:
By Adjustable Match Grips
The biggest selection of grips availabe in various sizes can be found in the Adjustable Match Grip program. Generally, the following size may be taken as standardised: S= 70-80mm, M=80-90mm, L=90-100mm, XL=100-110mm. Standard size = 85-95mm.
Because of the length and height of some pistols and revolvers the grips may vary individually somewhat from this norm in order that they may fit in the official ISSF measurement box. XL grips for Sport and Service Pistols are partially over the permitted size allowed by the ISSF.

By Service-Pistol, Revolver and Special Models
Standard size for these models is 83-98mm. Different models are also offered in S=70-85mm, XL= 95-105mm and XXL=100-110mm.

A further development of the very popular PPC/1500/Bianchi Cup pistol grips, it combines the most positive features of these grips with the SWO_XHO and SWO_YHO revolver grips and offer ambidextrous handling and a shorter shelf for the little finger of the second hand for an ideal double, hand-grip connection. The open back strap area with distinct palm swell, waisted form and the Rhomlas® surface texture bring confident control, even with heavy revolvers.
