NOTE: The 10MM variant uses the same body/receiver plate pattern so it accepts the same brace and stocks used on the 9mm variants.

These Picatinny-mounted (1913) Braces allow you to design and build the brace setup that best suits your needs. As long as you already have a Picatinny (1913) mount on the rear of your firearm with at least 3 slots, these braces will mount to it.
