The S10 +2 fits the S10 magazine, which runs only in Glock® 43X and 48 pistols grip-chopped by Shield Arms. It doesn't fit S15 magazines or factory Glock® magazines. Running an S15? See the S15 +2 Extension.

S10 +2

Twelve Rounds From an S10

The S10 sits flush at 10 for deep concealment. The +2 turns the same magazine into a 12-round spare for your pouch, or a carry mag for days when concealment matters less, from the same grip-chopped pistol.

Features

Built Like the Rest of the S-Series

  • Easy-Access Floor Plate

    Reach the spring and follower for cleaning or service without taking the extension off the magazine.

  • Index Cuts

    Cuts on the extension body give you a better grip when you pull the magazine from a pouch.

  • Billet 6061 Aluminum

    Machined from billet aluminum and finished with a Type II anodize. Made in the USA.

  • Spring for Life

    A lifetime warranty, plus free replacement springs for as long as you own it through Spring for Life.

S10 Family

Flush at 10. Extend When You Want More.

The +2 is the small step up. The S10 +5 takes the same magazine to 15. Both let you carry or reload with confidence.

A grip-chopped pistol also runs S15 and S20 magazines, up to 25 rounds. See every option.

Questions

S10 +2 Extension FAQ

Will it fit my S15 magazine?

No. The S10 +2 fits only the S10. For the S15, use the S15 +2 Extension.

Will an S10 fit my factory Glock® 43X or 48?

No. S10 magazines and extensions fit only pistols grip-chopped by Shield Arms. Our S10 Grip Chop Service converts the pistol you own.

Do I have to remove it to clean the magazine?

No. The easy-access floor plate opens to the spring and follower with the extension still on the magazine.

Extension or pre-installed?

Buy the extension to upgrade an S10 you already own. Buy the pre-installed version to get it already fitted to a new S10.

+2 or +5?

The +2 is the shorter option at 12 rounds. The +5 holds 15 and extends further below the grip.

What's covered?

A lifetime warranty against defects, plus free replacement springs for life through Spring for Life.

ODA Green

Used on: magazine extensions, magwells

ODA's (Operational Detachment Alpha) are the boots on the ground operational teams of a Special Forces Group. This color began as a special run for a deployed ODA. In continued support we have decided to continue the color as a standard offering and donate a portion of the proceeds to The Green Beret Foundation. Finish is anodized in green.

QPQ Nitrocarburizing Surface Treatment

Used on: magazines, barrels, slides

QPQ Nitrocarburizing is a type of surface treatment used to enhance the durability and corrosion resistance of metal parts. The process involves heating the metal in a controlled environment, where nitrogen and carbon are introduced to the surface of the metal. This forms a thin layer of a hard compound called "nitrides," which increase the surface hardness of the metal.

During the QPQ Nitrocarburizing process, the metal is immersed in a special salt bath and heated to high temperatures. The salt bath contains a mixture of chemicals that release nitrogen and carbon, which penetrate the surface of the metal. The process is carefully controlled to ensure that the nitrogen and carbon penetrate to a specific depth, creating a uniform layer of nitrides on the metal's surface.

The resulting nitride layer provides many benefits to the metal parts, including increased hardness, wear resistance, and corrosion resistance. This treatment helps to increase the lifespan and durability of metal parts, making them more reliable and long-lasting.

Any “scuffing” you see in the surface finish is completely normal, and will not affect the durability or corrosion resistance of the steel.

Electroless Nickel Plating

Used on: magazines

Silver electroless plating offers superior electrical conductivity and corrosion protection with excellent deposit uniformity and adhesion properties. This bright, reflective finish provides outstanding solderability and contact resistance while maintaining the consistent thickness and coverage that electroless plating processes are known for. Black electroless nickel plating provides these same exceptional deposit properties - including lubricity, hardness, and corrosion resistance - but with a fully conductive and uniform black surface finish that combines superior performance with an attractive dark appearance.
