Base Pad For Sig Sauer P320 9/40 Magazines

Product Description

Not for sale to California residents. A courtesy email will be sent to CA residents who place an order for a base pad that has the capability of taking a magazine past ten rounds. Ultimately a refund will be issued. CA residents can only purchase +0 base pads or GLOCK 43 and GLOCK 42 base pads. The 43 and 42 base pads do not take the mag capacity past ten rounds.

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 metal insert at the bottom before installation*

*Not compatible with carry size frames*

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

TTI Firepower +2 Base Pad for Full Size Sig P320 and Full Size X5 is compatible with:

  • 17 and 21 Round 9mm Magazine
  • 14 and 18 Round 40 S&W Magazine

Sig P320 +2 Base Pad is designed to work with stock magazine springs.

- Patented proven push pin design.
- 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.
- Used and endorsed by World and National Champions Bob Vogel, the GLOCK Shooting Team, Randi Rogers, Allie Barrett, and of course Taran Butler.

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.

  1. High-Quality Product!

    Posted by Tom K on Nov 11th 2019

    I've bought these for my Glocks in the past and love them. After initial install these seem just as good. And they're way easier to install on the Sig magazines than the Glock magazines. I bought these for a P320 X5 21-round magazines and in hindsight I think I would rather have the +5 Base Pads for 17-round magazines - They fit in the magwell a little better and I like the added weight too. But these will still work for CO in USPSA and are a very high quality product. Can't go wrong with any of them.

  2. They work

    Posted by Chris on Oct 25th 2019

    Don't laugh at the headline. Everyone has bought something that never worked like it was supposed to. Went from 21 to 23 Reloadable in all 4 mags. These are simple to put on and take off, without the need of extra tools. Empty mag, push pin, slide off, clean, put back together and your back shooting. On top of all that they look cool

  3. Best design out there

    Posted by EDWARD STJOHN III on Jul 16th 2019

    Tried other companies +5 pads for USPSA Major.40, could only get 17 rounds to feed consistently and set screw would not hold pad tight so I had a few mis-feeds in competition. Taran's design allows for 18 rounds with room and the push pin locking design is the only way to go. No issues to date. Will only use these pads from now on

  4. great design, good fit

    Posted by donald martin on Jul 3rd 2019

    I can get 23 in each mag. sturdy and look good. glad I got them

  5. Adds 2 rounds as advertised

    Posted by GeebsNC on Jun 26th 2019

    Received a pair of these earlier in the week. It took longer to unload the mags than it took to install them. They do indeed add 2 rounds, although the last one is tight. Haven't had the chance to function test them yet, but that won't take long. Quality appears to be excellent (as it should be for a $ 30 piece of machined aluminum).

    These were recommended by one of my fellow competitors. I bought them because I was tired of losing time every stage to a mag change. Faster to double-tap the target than aim precisely enough to neutralize it in 1 shot.

    I bought 2. If I like them, I'll buy 2 more and have them on all my mags. I'm running a P320 X-Five (and love it)

  6. Functional beauty

    Posted by mk on Jun 11th 2019

    The best design in the market, PERIOD. Easy to disassemble and re-assemble the mags with no tool, and the base pad stays securely on the mags. These look great too.

    As promised, these add two more rounds to each mag.

    Hell, my reload has gotten faster too, lol

    One thing to note for potential buyers: I installed this pad on all four mags that I have. I would say these mags have gone through half their life and all of them barely passed the mag gage. One issue that I see is that the spring pushes the pad out and elongates the overall length by 0.5 ~1mm. If you pressed the pad against the mag tube, the mag would pass. If not, it might fail.

    I wish the pad was a bit thinner / shorter in order to increase the room for 'variation' in, for instance, is the length of mag tubes.

  7. Looks great, but barely holds +2

    Posted by Christian Barrett on Jun 8th 2019

    When fully loaded with 19 rounds, the last round is so tightly forced in that it makes it difficult to seat the magazine into the pistol. If you have one in the chamber then insert the mag of 19, it makes cycling the first round almost impossible. Also, putting the last round in the magazine is very difficult. Due to me liking the look of the mag extension so much, I just use it as a +1.

  8. Awesome product.....

    Posted by Derwin Edmondson on May 23rd 2019

    I have several plates on various weapons....these didn't disappoint ....easy install and look great...will be purchasing more for other weapons I own.,,,highly recommend.,,,

  9. Great product

    Posted by Billy Ray Phillips on May 21st 2019

    Very cool looking design. Feels sturdy, and not cheap at all. I can only fit +1 in my .40 magazine, but its still awesome and worth the money!

  10. Disappointed whilst impressed

    Posted by Connor on May 7th 2019

    Install was easy and they stay on well. Constructed well and look great. My only issue is I cannot get the extra 2 rounds in the mag. I’m not sure what issue I’m having. I have pulled them apart and reinstalled them and still can’t get it to +2.
