Smith & Wesson M&P Compact .357 Sig/.40 S&W 10-Round Magazine with Finger Rest - Steel Blue

The Smith & Wesson M&P Compact 10-round magazine in steel blue with finger rest is a factory-original magazine built for shooters who run .357 Sig or .40 S&W in the M&P Compact platform. If you're carrying, training, or competing with an M&P Compact, genuine factory magazines are the foundation of reliable feeding—they're engineered to the exact tolerances of your firearm and backed by S&W's reputation for quality control. This 10-rounder strikes the practical balance between capacity and concealability that makes the Compact frame so popular for duty and personal defense.

The finger rest is more than comfort—it's functional design. During reloads, that rest gives your pinky finger a secure purchase on the magazine body, which translates to faster, more controlled mag changes under pressure. Whether you're running drills at the range or rely on your M&P for concealed carry, the finger rest helps you maintain a solid grip during the reload sequence.

Steel blue finish on the magazine body resists corrosion and wear. You'll want to keep multiple magazines in rotation—one loaded in the gun, spares in your range bag or duty belt—so you've got options if a mag takes a hit or needs cleaning. Factory magazines from the manufacturer eliminate the guesswork; you know they'll chamber and feed reliably with your specific M&P Compact.

Frequently Asked Questions

Will this magazine work with my M&P Compact?

Yes—this is a factory Smith & Wesson magazine engineered specifically for the M&P Compact platform in .357 Sig or .40 S&W. If your Compact is chambered in either of those calibers, this magazine will function as original equipment.

What's the difference between the finger rest and standard magazines?

The integrated finger rest provides a shelf for your pinky finger during reloads, giving you a more secure grip on the magazine body and enabling faster, more controlled magazine changes. Standard magazines without the rest leave your pinky hanging.

Can I use this 10-rounder with different M&P models?

This magazine is designed for the M&P Compact. Magazine compatibility varies across M&P product lines—check your firearm's manual or contact S&W directly if you're unsure whether it will work with a different M&P model.

Why choose factory magazines over aftermarket options?

Factory magazines are engineered and tested to the exact specifications of your firearm by the manufacturer. They eliminate compatibility guesswork and deliver the reliability you expect from a Smith & Wesson product.
