    Frequently Asked Questions:

    Can I use my 12rd and 15rd magazines? No

    Will the WC320 grip module work with .45 ACP or 10mm?  No, the WC320 magwell is too small for the large caliber magazines. There are no plans to support larger calibers at this time.  
    Will you offer a shorter, X-Compact / Subcompact (3-notch) length lightrail?  Not at this time, however there are plans to support this in the future. 
    Will you offer a Compact (15rd) length grip? Not at this time, however there are plans to support this in the future. 
    What basepads work with the WC320 grip module?  The WC320 grip module is compatible with all current production, X-Series basepads.  
    Will the WC320 grip module work with older, first generation basepads?  No, but a competent gunsmith can modify old basepads by removing the "ears" to make them work with the WC320 grip module. 
    Will the WC320 grip module work with aftermarket P320 basepads or magazines?  We cannot control the quality of other manufacturers parts, and therefore can only guarantee compatability with current production SIG factory magazines and basepads, however as long as they conform to SIG factory specifications they should work. 
    Will the WC320 grip module work with the older, first generation slide releases? Yes, the WC320 is compatible with the larger, first generation slide releases. 
    Will the WC320 grip module work with the P250?  No, it will not.
    Will the WC320 Tan grip module be an exact match to my current M17/M18 grip module & basepads?  No. Department of Defense compliance for coyote tan can vary greatly, so Wilson Combat chose to make our tan unique, and therefore the WC320 grip module may not exactly match the variety of coyote tan used on the M17/M18.


    What size is the WC320 grip module? Small, Medium, or Large?
    Measuring the circumference of the grip below the trigger guard, not including the high grip cut, the WC320 grip module is 5.4" (137mm). That makes it approximately the same size as SIG's small grip module, however the grip angle and shape are much closer to the timeless design of the 1911, so it's not a direct comparison between the two.


    Will my X-Five Tungsten Weight work in the WC320 grip module? No, the WC320 Grip Module uses rod-style Tungsten Weights.
