This is a factory Smith & Wesson M&P Shield 9mm 8-round extended magazine.
Thanks to its Plus 1 Grip Extension, this factory M&P Shield 9mm magazine promises unmatched concealment and reliability.

The factory polymer grip extension gives Shield 9 users that extra edger with increased control and maneuverability.

Key Features:

• Stainless steel body
• Steel feed lips and steel wire spring for consistent feeding
• Anti-tilt polymer follower
• Witness holes on both sides of the mag
• Advanced polymer baseplate, with easy access to the internals for cleaning

Compatible with both the original M&P Shield and M&P Shield M2.0 pistols chambered in 9mm; the grip extension does NOT feature the aggressive M2.0 texture.
