Description
This is a factory Sig Sauer magazine designed to deliver the same performance and fit you'd get from the mag that came with your pistol. Built from steel with a blued finish, it holds 10 rounds of 9mm and is engineered to feed reliably whether you're at the range or carrying daily.
The magazine construction follows Sig Sauer's OEM specification down to the dimensions, so you get a direct fit with the P228 and P229 without any compatibility questions. The 10-round capacity fits flush with the grip frame, giving you a compact profile that works well for both carry and range sessions. Numbered witness holes let you do a quick visual round count on the move.
Blued Steel Construction Built for Durability
The blued steel body and internal high-tensile spring work together to handle years of use without problems. A polymer baseplate absorbs impacts and comes off easily for cleaning and maintenance. Unlike some aftermarket options, this is the genuine factory magazine you need if you want to be certain it'll feed and function properly.
Versatility as a Spare or Replacement
Whether you need a backup magazine for your range bag, an extra for rotation in your carry setup, or a replacement for a worn original, this single unit serves all those purposes. The straightforward design means no surprises—just the reliable feeding and durability Sig Sauer is known for.

Frequently Asked Questions
Will this magazine work in both P228 and P229 pistols?
Yes, this magazine is designed for both models and follows OEM specification for direct fit compatibility. The 10-round standard capacity works in all P228 and P229 9mm pistols. If your P229 was manufactured after 2010 with the updated frame, make sure it's chambered in 9mm, as the frame geometry was revised for those models.
Can I use P226 magazines in my P229?
The larger P226 9mm magazines will physically fit in a P229, but they'll extend below the grip and won't seat flush. This isn't ideal for carry or concealment. Stick with magazines designed for the P228/P229 to maintain the compact profile and proper fit.
How do I maintain and clean this magazine?
The removable baseplate allows you to take it apart for cleaning. Simply remove the baseplate, slide out the spring and follower, and wipe down all components with a cloth. Inspect the feed lips for damage and ensure the spring still has good tension before reassembling.
Is this magazine suitable for carry or just range use?
This factory magazine is built for both. The blued steel construction is durable enough for daily carry and the flush-fit design keeps the profile compact. Many people rotate multiple magazines, using this one for both carry and range sessions.
