Since meeting with the Grayguns team at SHOT in February, we’ve been moving full-tilt toward developing a 140mm basepad for the hot new SIG 320. Greg Purcell is currently campaigning in the Northwest with our first-generation part, getting +5 (reloadable) or +6 (tight) in 9mm. Alma Cole is experimenting with spring/follower combinations, and reports +6 reloadable when using a modified CZ Tactical Sport spring/follower kit.
Our design blends concepts from our successful S&W M&P and HKVP9 basepads. The current 140mm part hits the lowermost corners of the frame (see photo at left), but two minutes of trimming eliminates the conflict. SIG 320 grip frames interchange easily and cost $40, so shooters modify them to suit at the drop of a hat.
You’ll find the basepad kit (with custom spring) in our store here.
COMING SOON: Shooters that want more length, but no extra capacity will love our “triple threat” basepad — build to suit IDPA, SPP, and USPSA “Production”, the “triple threat” enhances the mag in several ways.
