MAG SIG P229 9MM 15RD OLDER MODELS

Description

The Sig Sauer MAG-229-9-15 is a factory original magazine for older-generation P229 pistols chambered in 9mm—the pre-E2 frames that preceded the updated grip module design. If you run a legacy P229, factory magazines matter more than they might seem: the feed geometry, follower angle, and lip dimensions are all matched to the original barrel and chamber specifications rather than adapted from a later revision. Using the correct magazine for your generation of pistol is the most straightforward way to keep feeding consistent across a full range of ammunition profiles.

The body is constructed from heat-treated stainless steel with a corrosion-resistant finish, which holds up to the moisture and debris a carry gun encounters over time without sacrificing structural rigidity. A steel wire spring drives the injection-molded polymer follower, a pairing that maintains consistent round presentation under load and after extended periods with the magazine fully charged. The polymer floor plate is flush-fitting, which keeps the grip profile clean and avoids snagging on a holster during the draw—and it’s removable for routine inspection and cleaning without additional tools.

Precision-machined witness holes along the body let you verify round count visually when time doesn’t allow a full unload-and-count. Sig sources these magazines from multiple manufacturers built to their own specifications, so minor differences in stamping or finish tone between units are normal and do not indicate a quality or compatibility issue. This is a straightforward replacement or backup option for shooters who want to stay with genuine Sig components on an older platform rather than introduce third-party variables into a pistol they already trust.
