Mec-Gar Extended Performance Magazine - 20-Round Capacity, 9mm Luger, Heat-Treated Carbon Steel Body, Anti-Friction Coating, Black - MGG172003A
Product Description
Staging a duty handgun, dynamic competition rig, or home-defense pistol-caliber carbine (PCC) requires a feeding engine optimized for flawless structural indexing. Standard factory polymer shells carry a wider exterior cross-section that can drag against tight mag-well tolerances, while low-capacity alternatives leave you short during extended range fire loops. The **Mec-Gar® Glock 17 20-Round 9mm Extended Magazine (MGG172003A)** completely flatlines these tactical constraints. It delivers a premium, Italian-engineered steel magazine that increases capacity while reducing friction layout thickness.
Proudly manufactured by the world's leading tier-one magazine specialist, this high-volume option features a unibody **heat-treated carbon steel housing**. Unlike thick factory multi-component polymer walls, the structural sheet metal is stamped thin and treated with Mec-Gar's proprietary **Anti-Friction Coating (AFC)**. This specialized outer treatment ensures lightning-fast drop-free actions, blocks rust tracking, and significantly reduces the hand effort required during manual cartridge staging. Up top, precision-formed feed lips keep a rigid hold on cartridge geometry, while a high-visibility lime green anti-tilt follower is driven by a high-tensile spring wire for continuous upward presentation.
Equipped with a custom-molded polymer **plus-3 (+3) extended base pad** for fast reloads out of tactical pouches, this turn-key utility asset upgrades your ammunition readiness directly from your workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The Mec-Gar MGG172003A magazine assembly arrives fully built and ready for staging inside an authentic retail display pack. GLOCK 9MM HUB INTERFACE MATRIX: This extended 20-round steel magazine is explicitly engineered natively, strictly, and cross-compatibly to lock inside **full-size 9mm Glock-pattern magazine wells across Generations 1 through 5**. *Firearm Fitment Checklist:* It seats cleanly into the **Glock 17, G34, G45, and G47**, drops into compact variants like the **Glock 19 and G26** with extended body stickout, and functions flawlessly inside **9mm PCC platforms** configured for standard Glock lower inputs on your bench. Jurisdictional Capacity Notice: This extended block retains 20 rounds total; ensure strict local compliance with all regional high-capacity tracking restrictions before placing this on your armorer workspace. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host firearm platform is completely clear of live ammunition, the magazine is removed, and the chamber area is empty and safe. 2. When loading a brand-new high-tension spring, use an alignment speed loader tool to comfortably slide past early coil resistance. 3. Tap the rear spine vertical wall against your palm periodically during loading to align the 9mm Luger case rims flat against the steel inner tracks. 4. Clean the external AFC metal sleeve with a dry microfiber rag; do not spray liquid oils inside the magazine tube, as damp surfaces attract aerosol carbon residue and cause follower binding downrange.*
Key Features
- Extended 20-Round Capacity: Adds 3 extra rounds over standard flush configurations, giving you longer firing strings and more target coverage without stopping to reload.
- Proprietary Anti-Friction Coating: Finished in an ultra-slick, hard anti-friction layer that ensures lightning-fast drop-free mag changes and makes loading by hand much easier.
- Heat-Treated Carbon Steel Body: Stamped from premium carbon steel and heat-treated for maximum structural durability to prevent feed-lip spread or body bending.
- High-Visibility Anti-Tilt Follower: Fitted with a bright lime green polymer follower that glides smoothly up the steel walls and provides a clear visual empty signal.
- Impact-Resistant Plus-3 Base Pad: Outfitted with a heavy-duty extended floorplate that provides extra grip surfaces for fast handling and absorbs hard drop impacts on the range.
- Sleek Steel Profile Advantage: Thinner wall geometry than standard thick polymer magazines provides smoother clearing space inside customized or tight mag-wells.
