Henning Group — Magazine Extensions, Basepads & the T-900 Mag Pouch System
Henning Group makes magazine extensions and basepads for more competition pistol platforms than almost any other manufacturer in the market — from Glock and M&P to Canik, Walther PDP, CZ, Tanfoglio, and 2011 double-stack magazines. If you're trying to squeeze the maximum legal capacity out of your competition magazine at 140mm, there's a good chance Henning makes the extension for your specific platform.
Magazine Extensions & Basepads by Platform
- Glock — +6 basepad and spring kit (17→23 rounds, 141.25mm) for G17/34/19X/45. EDC +3 extension for G19/23 compact carry. Blueline extension/basepad options.
- S&W M&P — +6 extension bringing capacity from 17 to 23 rounds at 141.25mm. Compatible with Ed Brown and factory S&W magwells.
- Canik — +4 extension for Rival, TP9 SF/SFX, and METE series. Brings capacity from 18 to 22 rounds. Fits both steel and polymer models with spring-loaded steel detent for secure, easy-off mounting.
- Walther PDP — +4 extension for PDP Full Size (18→22 rounds)
- CZ — extensions and basepads for CZ 75-pattern magazines
- Tanfoglio / EAA / IFG — +6/7 extended basepad for Tanfoglio Limited and Open magazines
- 1911/2011 — basepads for single-stack and double-stack competition magazines
MBX Follower Compatibility
Most Henning extensions can be paired with an MBX Extreme or CSRG follower and spring kit to squeeze additional capacity beyond the extension alone — for example, a Glock 17-round magazine with Henning +6 extension and MBX follower can reach 24+1 rounds. Note: aftermarket competition followers typically do not lock the slide open on the last round — this is a standard tradeoff for maximum capacity.
T-900 Adjustable Speed Mag Pouch System
The Henning T-900 is a modular magnetic magazine pouch system built around a 30-degree rotational cylinder hanger — adjust both distance from your body and rotational angle for a fully personalized competition mag pouch setup. The hanger is available in Black, Red, Silver, and Blue, with belt attachment for 1.50" or 1.75" belt width.
The magnetic Speed Mag pouch inserts are sized for specific magazine families — order the pouch that matches your platform:
- 01XL — 1911 Single Stack magazines
- 02 — CZ 75, Canik, Beretta 92, Tanfoglio Small Frame, Walther PDP Full Size
- 03 — CZ Tactical Sport, S&W M&P, H&K VP9/P30, Walther PPQ/PDP Compact
- 04 — CZ P10, Sig Sauer P320, Tanfoglio Large Frame
- 05XL — 2011 Double Stack magazines; also works for 03/04 users who want a stronger hold or run 170mm magazines
- 06 — Glock 17-size for MBX steel magazines only (not compatible with factory plastic Glock magazines)
Pouches are sold separately from the hanger for shooters who want to switch between magazine types without replacing the entire mounting system — a genuine advantage if you compete with more than one pistol platform.
USPSA Division Legality
Henning magazine extensions typically bring magazines to 141.25mm (5.56") — the maximum length allowed under the USPSA 140mm magazine gauge for Limited and Open division. Verify current rulebook compliance for your specific division and platform before competing.
