    Quality as usual

    Grams follower/spring kits allow me to get 23 rounds of 9mm in a SIg mag with Taran Tactical + base plate. Just what I need for USPSA CO division

    This worked extremely well in my 17 rd mags with Taylor Freelance +5. Would not lock back on last round with TF springs. Perfect now

    Does the job well

    I had feeding issues with my factory 21 round mags for my Sig P320 X5 Legion. These 141mm mags had Tarin +2 base pads and ran perfectly for about 6 months with the stock OEM springs. Then I started to have feeding issues and decided to change the mag springs. Could not find stock springs so I originally went with the Springer replacements. With the Springer springs I could only get a maximum of 19 rounds in my 21+2 springs so back they went. Decided to give these a try with the Grams followers. So far I’ve only dot one match with them but they worked flawlessly. It is easy to get all 23 rounds and because of the low Grams profile that last round is nowhere near as tight. So to sum it up, the product works as intended.

    Works perfect with the +2 extensions. Last round loads easy.

    Love these

    I relly only get these kits for the followers. The springs just wear out to fast, pair this follower with a TTI spring and it will run for years!

    An excellent fix

    I recently saw this replacement spring kit and follower for my Sig Sauer 17 round magazine for my P320 compact 9 mm, the factory ones that I purchased would not let me load 17 rounds and when I was able to I could not pull the slide back to charge a round, I had to settle for 16 rounds plus one in the chamber, I bought one to try and it was a quick fix, so now I just ordered another one for my other magazine, thank for a great product, I highly recommend it for anyone that is having the same problem that I had.

    A great fix for my 17 round magazine

    Posted by Unknown on Mar 4th 2018

    I saw this spring kit when i did a search for a new spring kit for my Sig Sauer 17 round magazine for my P320 compact extended magazine which was giving me so many problems trying to fit 17 rounds, i replaced the existing kit with this new follower kit and spring and it fit perfect and was able to slide open the first round with ease and it followed excellent, so i am ordering another kit today for my other magazine, thank you .

    A fix for my problem

    Posted by Matt on Jan 26th 2018

    I own a p320 carry in 9mm, some magazines function 17+1, some do not. Slight differences in followers or spring thickness was creating a situation where the follower or spring would bottom out and be so tight that in 17+1 It would not cycle the 2nd round regardless of use, ammo type ect. Bought one to test on one magazine. So far so good, maintains slide lock and does not bottom out. I will be ordering more next week to put in the other problem magazines!
