Armscor® / Rock Island Armory® 1911 A2 High-Capacity .45 ACP 13-Round Factory Magazine - Heavy-Duty Steel Construction, High-Tension Spring, Polymer Base Pad, Blued Finish - 54171 / 4806015541714
Product Description
Standard single-stack 1911 handguns offer legendary trigger breaks and slim profiles, but their 7- or 8-round capacity leaves shooters reloading frequently during high-volume range sessions or tactical matches. Double-stack 1911 A2 models solve this limitation by widening the magazine well to hold significantly more ammo without compromising classic 1911 ergonomics. The **Armscor 1911 .45 ACP 13-Round Pistol Magazine (54171 / 4806015541714)** delivers true factory-original reliability and high-capacity performance for your wide-body .45 ACP pistol.
Manufactured by Armscor / Rock Island Armory, this 13-round magazine is built from heat-treated steel with a smooth blued protective finish that resists corrosion and facilitates effortless, drop-free mag changes. Inside, a heavy-duty steel spring and anti-tilt follower maintain consistent upward pressure on heavy .45 ACP rounds to prevent nose-diving and feeding jams. Finished with an impact-resistant polymer base pad that cushions drop impacts on hard surfaces, this factory magazine ensures smooth, dependable cycling round after round.
Designed specifically for Rock Island Armory double-stack 1911 A2 pistols and compatible wide-body platforms, this 13-round factory magazine provides robust construction and seamless feeding directly from your workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The Armscor 54171 factory magazine comes pre-assembled and ready for range action. PISTOL FITMENT MATRIX: Fits **Rock Island Armory (Armscor) 1911 A2 double-stack / high-capacity models in .45 ACP** (such as the RIA A2 FS HC .45 ACP series and Para-Ordnance P14 style frames). *Single-Stack Note:* Will not fit standard slim single-stack 1911 A1 frames. Workbench Setup Steps: 1. Always confirm your firearm is completely clear of live ammunition with the chamber empty before loading or testing magazines. 2. Inspect the steel feed lips and body to ensure no transit debris or excessive oil blocks cartridge movement. 3. Hand-load .45 ACP cartridges into the double-stack tube—a speed loader helps compress the heavy spring when loading those final rounds. 4. Seat the magazine firmly into your high-capacity 1911 magwell until the mag release catch clicks securely into position. 5. Manually cycle the slide to verify positive feeding and slide lock-back on empty before live-fire training.*
