The SIG 320 +5+ basepad takes full advantage of the 140mm overall length allowed in USPSA and 3-Gun competition.
Custom springs and a quick-release stainless locking plate make this a go-to part, whether or not you compete.
This latest update includes a relief cut to improve the way the floorplate slides up into the frame. Requires no modification to the gun or magazine -- easy to install.
