Description

Our kit includes the following:

  • CSRG Multi-Platform Competition Follower made from durable nylon
  • CSRG Competition Spring (made by ISMI)
    • Options available for 11 or 13 coils
    • 13 coils will improve reliability and longevity, but may result in slightly reduced capacity compared to the 11 coils
  • Competition follower does NOT lock the slide open after firing the last round
  • 23/24/25+1 capacity when used with 140mm magazine extensions and full-size factory magazine tubes
  • We recommend using a loading tool such as an UpLULA to achieve best results, and to fully load and unload the magazine a minimum of three times to set the spring.

We have tested the followers in the following firearms (full-size magazines with 140mm magazine extensions):

  • Beretta PX4 Storm (24/25+1 with Springer Precision 140mm basepad, 22+1 with Beretta factory 20 round magazine; metal floorplate must be removed)
  • Beretta 92
  • Girsan Regard
  • Springfield Echelon
  • SIG P320
  • Glock 17/19/45/47 (not compatible with Magpul or Mecgar magazines)
  • Stealth Arms Platypus
  • CZ Shadow 2
  • Jericho 941
  • Tanfoglio Stock 2
  • Walther PDP
  • Walther PDP SF
  • Smith & Wesson M&P9 2.0
  • CZ Czechmate 
  • CZ Tactical Sport
  • SIG P226
  • Grand Power X-Calibur

We recommend the following extended basepads for optimal performance:

  • Taran Tactical
  • Henning Group
  • Springer Precision

Please note: these followers are designed only for range and competition use. This follower and spring kit are not intended for duty use.

    Must have upgrade.

    Posted by Michael Tran on Aug 7th 2025

    This combo is a must for competitive shooters. Installed these when they arrived and no issues right of the box. Reliable feeding with various types of rounds. Does take a few loads/unloads to get the springs to settle to reach easy loading. Dont think twice, just add it to your cart.

    Great quality spring/follower kit

    Posted by Zach davis on May 23rd 2025

    Chose these for my glock mags over the mbx stuff and they work flawless. I’m able to get 24+1 in my glock 47 with Henning basepads and function/quality has been fantastic for the first 1k rounds.

    Reliable springs with excellent service

    Posted by Jacob Lux on Apr 29th 2025

    13 coil springs run 100% in my Glock 47. I needed new springs three days before a major match and Keanu was able to get them to me quickly, saving my match. Excellent customer service.

    Works for PX4

    Posted by Charles Williams on Jul 17th 2024

    Works for PX4 mags unlike MBX springs. Gives 24+1 with my Springer extensions. Needs some breaking in. Might run them as 23 for a while, but that rivals what I was getting with a similar setup in my 92GTS.

    PX4!

    Posted by Matt Hogue on Jun 5th 2024

    They work excellent and 100% reliable in my PX4. With Springer basepads I can start with 24+1 and then leave the reload mags at 23.

    Fast Shipping and Ran Great!

    Posted by Larry Kouns on Jun 4th 2024

    They arrived super fast. Before I even started checking the tracking. Ran perfectly in my shadow 2 giving me 23+1.

    Expected a bit more then what I got

    Posted by Jack Lawler on Jan 2nd 2024

    I thought I would be able to get 25 out of my M&P with the TTI extensions but I got 24 and the follower keeps popping out the top of the mag not sure I trust that.
