SIG P320 +5 BASEPAD Reviews & Ratings

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.

Best extension

Very solid extension. It also fits into the magwell with no trimming needed.

Does not fit .45

I read some of the questions about this fitting the .45. Skeptical I purchased and it does not fit. I was able to get the extension to fit on the mag with an extreme amount of effort, but the mag would not feed properly.
