Part/Model: 1593
Keep your .357 SIG Glock® magazines feeding smoothly with the Glock .357 Magazine Follower (1593)—the OEM replacement designed to restore reliable presentation, consistent lock-back on empty, and proper stack angle across 9-, 11-, 13-, and 15-round magazine bodies. Whether you’re refreshing high-mileage mags, converting mixed parts back to factory spec, or solving nose-diving and last-round issues, this caliber-specific follower is the simple, inexpensive fix that brings your mags back to Glock-reliable performance.
Why Upgrade/Replace Your Follower
Restore reliability: A fresh OEM follower corrects worn or tilted geometry that can cause misfeeds, bolt-over-base, or failure to lock back on empty.
Caliber-specific design: Engineered specifically for .357 SIG stack angle and case profile for consistent presentation into the feed ramp.
Factory-correct fit: Works with Glock’s 9-, 11-, 13-, and 15-round .357 SIG magazine bodies when paired with the proper spring.
Drop-in service: Simple field install—no gunsmith required—and an ideal time to inspect/replace the mag spring.
Training & duty ready: Keep range and carry magazines on the same factory spec for consistent function and feel.
Compatible Pistols & Capacities*
Glock 33 (Subcompact): 9-round magazines (and many 10-rd compliant bodies)
Glock 32 (Compact): 13-round magazines (and 10/11-rd compliant bodies)
Glock 31 (Full-size): 15-round magazines (and 10/11-rd compliant bodies)
*Always verify your magazine body, caliber markings, and spring before installation. Some regional/compliance magazines use different internal blocks that may affect follower travel.
Signs You May Need a New Follower
Last round fails to feed or the slide doesn’t lock back on empty
Visible chipping, cracking, or rounding on the follower nose or rear pad
Intermittent nose-dives with certain bullet profiles
Excessive tilt or sluggish movement when you press the follower by hand
Installation (Quick Guide)
Unload & clear the firearm; remove the magazine.
Disassemble the magazine (depress floorplate button, slide off floorplate; capture the spring).
Swap followers: Detach the old follower from the spring; clip the 1593 follower onto the spring in the same orientation.
Reassemble the mag, ensuring the spring leg orientation matches factory setup.
Function check: Hand-cycle dummy rounds; confirm smooth feeding and positive slide lock on empty.
Pro Tip: If your mag has high round count or weak lock-back, replace the spring at the same time you install the new follower for best results.
Best Practices
Keep calibers matched: Use .357 SIG followers only in .357 SIG magazine bodies.
Inspect springs & feed lips: Followers can’t compensate for cracked feed lips or collapsed springs.
Number your mags: Mark baseplates (1, 2, 3…) to track any future issues to a specific magazine.
Test your carry ammo: Run a full mag of your chosen defensive load to confirm reliability before duty or carry.
