TTI Sig Sauer P320 9/40 +5 Basepad by Taran Tactical 

This TTI base pad does add a little extra weight to the magazine which helps the empty mag drop free easier for faster reloads. This TTI SIG base pad, just like all of our base pads, is designed to give you the edge over your adversaries. We use our patented push pin design to lock the base pad to the magazine, which makes for easy field stripping and cleaning your magazines between stages. Just push down the pin, slide the base pad onto the magazine and push the pin up to lock the base pad onto the magazine. Our one piece design is great because there are no extra parts or tools needed to attach the base pad to your magazine. The base pad itself is machined out of billet aluminum and is hard anodized to ensure durable long lasting color. All machining and manufacturing is done in the USA. 


  • This Sig P320 +5 includes a 10% stronger spring with purchase
  • Patented proven push pin design.
  • Adds +5 rounds to 9mm.
  • Adds +3 rounds to 40 Cal.
  • Super easy to attach and detach from the magazine.
  • No specialty tools or devices required to disassemble.
  • One piece design, no extra parts to possibly lose during disassembly.
  • The added weight helps the magazine drop free easily for faster reloads.
  • CNC machined from billet aluminum.
  • Hard Anodized.
  • Made in the USA.


The pin set screws are set with Loctite® at the specific tension we recommend, and will generally never need an adjustment. Tightening the base pad screw is not recommended and may be difficult because the screw is set with Loctite®; trying to force the set screw to turn could result in stripping the screw. We do not warranty base pads for stripped heads on set screws or pins lost in result of tampering with the set screw. 

*Remove the plastic floorplate at the bottom before installation* 

*Due to magazine variances, some magazines may require slight modification to fit the 140mm gauge. Please contact TTI for further details.* 

*Not compatible with carry size frames* 

*This base pad is compatible with the stock P320 X5 magwell*

    Perfect for USPSA

    Posted by Shane Tankersley on Jul 13th 2020

    Using on the 17 rd. P320 X5 Legion magazines with the follower that came with the magazines and the replacement spring that came with the base pads. Meets the 141.25 mm mag length and got +5 (22 total) easily. Can force a 23rd round, but too tight to reload or chamber. Works with or without the Legion magwell. Can't wait to take them to my next match this week.

    So nice!

    This fits on 17/21 round mags can confirm. 21 round mag has a gap between magwell so not my cup of tea 17 round mag looks perfect. Easy to install Perfect weight Great finish

    Best base pads hands down

    Posted by Thomas James Swearingen III on Jun 22nd 2020

    these base pads are not only great looking but the fit and finish are outstanding, installed in seconds and functions just like OEM. Highly recommend this product.

Add a spring and follower kit below to get an extra round!
