Glock OEM Mag Catch Spring

Factory Mag Catch Spring

This is the genuine Glock magazine catch spring, part number SP00280. It is the small straight wire that pushes the magazine catch into engagement so a loaded magazine locks in place and stays there until you press the release. When the spring wears, magazines can seat loosely or drop free unexpectedly, so this part is a common replacement during maintenance and full pistol rebuilds.

Features

• Genuine Glock OEM Part — OEM, or original equipment manufacturer, means it is made by Glock to the same factory specification as the spring your pistol shipped with.
• Stainless Steel Construction — Stainless steel resists rust and keeps its tension through repeated magazine changes.
• Straight Wire Design — The spring is a single straight rod rather than a coil, matching the wire-style magazine catch setup.
• Powers The Magazine Catch — It applies the constant pressure that holds the catch against the magazine's notch.
• Restores Magazine Retention — Fitting a fresh spring brings back firm lockup if magazines have started to seat loosely or fall out.
• Broad Model Coverage — Listed for G17, G17L, G19, G20, G20SF, G21, G22 through G41, plus G42 and G43.
• Not For G21SF — This spring does not fit the Glock 21SF.
• Manufacturer Part SP00280 — The Glock part number makes it easy to match against a parts diagram or armorer's list.

Fit And Compatibility

The spring sits in the frame and bears on the magazine catch, so replacing it is a routine armorer-level job. It is listed as compatible with most full-size, compact, subcompact and slimline Glock models, with the G21SF the stated exception. Before ordering, confirm that your pistol uses the straight wire-style magazine catch spring shown in the photo.
