ProMag SMIA24 20rd 9mm Fits S&W CSX Blued 4140 Heat Treated Steel

Description

This is a ProMag 20-round 9mm magazine.

This is an extended magazine, adding rounds at the cost of some grip length and concealability. Magazines are consumable: springs and followers wear before the body does, so buying spares and rotating them is cheaper than chasing feed problems later.

Several states and cities cap magazine capacity, and those limits change. Check your state and local rules before ordering – we ship to your address or your dealer, but we cannot ship a magazine somewhere it is not legal. Magazines ship directly to you with no FFL transfer.
