Glock 45 OEM Magazine

Power up your Glock 45 with a factory-spec Glock 45 OEM Magazine. It delivers 17 rounds of 9mm capacity, smooth feeding, and the dependable performance Glock shooters trust. Seat it fast, run it hard, and reload with confidence for carry, range, or home defense.

Product Description | Specs for Glock 45 OEM Magazine

Engineers build the Glock 45 OEM Magazine with a rugged polymer body and a steel insert that stands up to repeated reloads, drops, and daily handling. It holds 17 rounds of 9mm Luger and feeds them reliably through a coil spring and a low-friction follower. It features the ambidextrous magazine catch cut that suits the Glock 45’s Gen 5 frame, so you can run a reversible magazine release from either side.

The Glock 45 pairs a full-size frame with a compact-length slide, and its magazine seats positively in the magwell and drops free when you hit the release. Keep a few spares on hand for your crossover build.

What’s the Glock 45 OEM Magazine Made Of?

Manufacturers mold the magazine body from high-strength polymer and reinforce it with a steel insert for rigidity and feed-lip durability. A steel coil spring drives the follower, and the polymer follower reduces tilt and helps cartridges feed smoothly from the first round to the last. The textured exterior resists slipping, and the materials withstand corrosion, impact, and everyday wear.

Customization Options

• Base Plates: Swap in an extended base plate for extra grip surface or added capacity if your build calls for it
• Magazine Springs: Install a replacement spring to refresh older magazines
• Followers: Upgrade to a compatible follower for added feeding consistency
• Marking and Organization: Label your magazines to track rotation and wear

Note: Aftermarket modifications may affect reliability or warranty. Test any change thoroughly before relying on it.

FAQs

Q: How many rounds does the Glock 45 OEM Magazine hold?
It holds 17 rounds of 9mm Luger.

Q: Will this magazine fit my Glock 17 or Glock 19?
Glock 45 and Glock 17 magazines share the same 17-round pattern, and Glock 17 magazines generally fit Glock 19 pistols and sit slightly proud at the base. Always confirm fitment for your specific model.

Q: Can I use it in a Gen 3 or Gen 4 Glock?
Generally yes. Gen 5 magazines work in earlier 9mm Glock frames, but test function before use.

Q: Why choose OEM over aftermarket magazines?
Aftermarket options can perform well, but OEM magazines match factory tolerances and typically deliver the most consistent feeding and seating.

Q: How often should I replace the spring?
Inspect your magazine regularly and replace the spring if you notice weak feeding, a sluggish follower, or visible wear.
