Would you like us to modify the follower so that your slide does not lock back? (See below for more info)*
If so, what numbers? Select between 1-8. (+ $10.00)

The Brazos Super-Tuned 170mm "big stick" magazine, available only in 9mm and 38 Super, uses all premium parts.  It starts as an STI tube and a Grams spring/follower kit.  Then you select either a Dawson or Taran Tactical basepad.  These parts are assembled and tuned for reliability and maximum capacity. 

  • Tube dimensions (inside and out) are set for maximum feeding reliability.
  • Lips of the tube are set to optimum specifications and polished.
  • All sharp edges are rolled.
  • The tube is polished both inside and out to a high gloss, slick finish.


Magazines are tuned to fit the U.S.P.S.A. gauge.  The 170mm  mag will hold 28+1 rounds of 9mm/38 Super.

Maximum capacity is achieved and is the same with any of the available basepads.  Which basepad is a matter of personal choice.  Both the Dawson and Taran Tactical basepads are made of aluminum.  Some prefer the lower profile that the Taran Tactial pads provide, while others prefer the tool-free on/off feature of the Dawson pads.  For 38 Super, best results are achieved when ammo is loaded 1.235" or shorter.

If your gun is set up to not lock back, we can modify the follower (without compromising capacity) so that your slide does not lock back.  Please indicate your preference above.  If you experience problems with premature slide lock back, please note that the pawl of your slide stop may need to be adjusted.  Refer to the link below on setting up your gun for slide lockback or not.

 Numbered Mags Available:  If requested, we will laser engrave a number in your magazines for an additional charge of $10 per magazine.  Please note that numbered magazines cannot be returned or exchanged
