Description Installation Instructions

Looking to speed up your reloads? These Sig P320 magazine extensions are a great upgrade for your pistol. Not only do they enhance your grip on the magazine when doing mag changes, the extra weight from the solid aluminum base pad also ensures that your magazine falls free.

Designed with the shooter in mind, all sharp corners and edges have been rounded off to ensure that there are no “hot spots” that result in pain when inserting the magazine.

Manufactured in Canada with Canadian magazine capacity laws in mind, these mag base plates add no extra capacity so there is no need to re-pin your mags. Simply remove the factory base pads and slide these ones on!

    • +0 Magazine Extension for Sig P320 9mm and .40 S&W Magazines.
    • Fits mags with both the "round" and "square" style mag inserts.
    • Adds no capacity - No need to re-pin your mags.
    • Easy to install! - No special tools needed.
    • Works with nearly all brands of magwells.
    • CNC machined from 6061 billet aluminum.
    • Made in Canada!

5 of 5 Excellent customer support February 5, 2023
Reviewer: CK from Winnipeg  
I emailed asking for some help deciding on which base pad to use with my Sig pistols and got a response the next day with the exact information I was looking for. Order was received and processed very quickly with shipping the very next day. After opening and installing the new base pads, they worked exactly as described with both my Sig P320 X5 Legion and my Sig P320 M17. Get the Standard Frame size if you're going to install these on mags and want them to work with both frame styles!

Big thank you to James for making great products and for the quick response to my question!

5 of 5 0 mag extension July 9, 2021
Reviewer: DV from Vancouver BC  
Ordered 4 of these off the bat after my questions were answered by JF. Easy install and works perfectly well with the magwell on my X5 grip module. I will definitely by more as I increase my mag count. Shopping was quick too. Made in Canada!!

5 of 5 Awesome product! September 19, 2020
Reviewer: Andre Girard from Quebec, QC Canada  
Tried 2 of these during a match and immediately ordered 4 more for the next one. The extra length and weight makes all the difference. Even better than the original x5 legion basepads which are supposed to be competition ready. My reloads got easier and faster instantly!  Also, customer service is second to none!  Highly recommend this product, made in Canada!
