Go to Springer Precision, they say which base makes 140mm with which tube 17 or 21/22. Might check Taran Tactical too. TT has a sale through tonight, so go burn up those credit cards!

Yeah, wanna pick up a couple when they are on-sale (my fav word next to free). Link to comment Share on other sites More sharing options...

love2fishnshoot Posted September 8, 2020 Share Posted September 8, 2020 I’ve always been a fan of the TTI pads. Had them for glocks and 2011s. Need to upgrade the ones on my 21 round sig mags. Haven’t done it yet but was unsure if the +2 would still be legal for CO but glad I read through to confirm it does. Link to comment Share on other sites More sharing options...

What are we talking about here? 17 round mage with + 5 extensions, or the 21 round mags with +2 extensions? Did you check them with the stock base pads if they were the 21 round mags? My 21 round mags were illegal with the stock plastic Sig base pads. Typically its the mag tube that needs a bump with the dremel to make them legal when it comes to the 21 round mage tubes with the +2 mag extensions. Be super careful when doing any modifications with the feed lips. Let me know if you need more clarification on to what I am talking about.

Boomstick303, All my 320 mags with TTI extensions fit the gauge but they are right on the edge. I'd be very interested to know what you've done with your feed lips as to give myself a little wiggle room. Thanks. PS: Do you have any pictures?

Chutist Posted September 29, 2020 Share Posted September 29, 2020 I have the TTI +5 and +2 on my 17 and 21 rounders, respectively. No issues yet, but I've only got a couple of matches on them. They are VERY tight fully loaded. I have been going one down just to make it easy. No stages so far where that one additional round was needed... so far!

I just bumped the rear corner ever so slightly with a sanding wheel on the dremel. I mean just touched it, and they all fall into the gage. Its tight but they all pass. I have had to do this to about 30% of my 21 round mags. Link to comment Share on other sites More sharing options...

What I found was that my older 17 round mags (Made in the USA with circle notch in factory baseplate) did not fit the gauge with TTi or Springer. The newer mags (Made in Italy with square notch in factory baseplate) all fit the gauge fine with both extensions. Link to comment Share on other sites More sharing options...
erwos Posted October 5, 2020 Share Posted October 5, 2020 Dumb question time... I have a pile of factory 21rd'ers with the plastic extended base plate. No one's gonna say anything about these at a club match, but in case I accidentally wind up at a Section or Area match next year, I'd like to be 140mm box compliant for Carry Optics. What is the preferred extension at this time? Springer+Grams or TTI? The irony is I don't care about capacity very much, 21 or 22 or 23 rounds isn't a make or break for me given where I am skill-wise. Link to comment Share on other sites More sharing options...

I don't know if it's the "Preferred extension" but i sure saw a bunch of TTI 's at the matches.. That's part of the reason I went with them. The Springer ->needing to drill was a non-starter. I looked hard at them, I bought their plate to mount my optic. Edited October 5, 2020 by Chutist Link to comment Share on other sites More sharing options...
George16 Posted October 5, 2020 Share Posted October 5, 2020 (edited) TTI is the most popular in my area. I’m using the +2 for my 21 round mags. Edited October 5, 2020 by George16 Link to comment Share on other sites More sharing options...
OPENB Posted October 5, 2020 Share Posted October 5, 2020 I’ve had both, and prefer TTI. But if you don’t care about capacity, save a bunch of $ and just careful make the stock plastic bases compliant. Link to comment Share on other sites More sharing options...

Thanks to everyone for the advice... I suppose I'll wait for the next TTI sale and pick them up then. Link to comment Share on other sites More sharing options...

regor Posted October 7, 2020 Share Posted October 7, 2020 Has anyone tried the Henning basepads for the P320? Looks like they only make 140mm extensions for the 17 round mags. Link to comment Share on other sites More sharing options...
Butterpuc Posted March 17, 2021 Share Posted March 17, 2021 I am a new P320 owner, I have been a huge Glock fan boy for years and use TTI +6 (9mm) base pads on my Glock mags. I keep seeing lots of people on this thread saying they are using a +5 TTI base pad, so you are only running 22 round magazines, 22 + 1 ? Then with regards to the 21 round mags, it seems a +2 TTI will get you 23+1, which is what I am used to with my 17 round Glock mags. Also, before I purchase more mags, do I just need to hold out and wait until some 21 round magazines come available? Link to comment Share on other sites More sharing options...

Adding the Henning base pads to 17 Round Sig P320 magazines gets you to 23 round reliably, and has room on the measurement gage to spare. Unlike adding TTI base pads to 21 Round Sig P320 magazines where I have to remove some material for them to pass the measurement gage on about 50% of the magazines.
