Sig Sauer 1203721-R P229 Recoil Spring .40 S&W / .357 Sig - Black

The Sig Sauer P229 Recoil Spring is a factory OEM flat-wire recoil spring designed for P229 pistols chambered in .40 S&W or .357 Sig. Manufactured from steel with a black finish, this direct-fit replacement restores reliable slide cycling and lockup on P229 duty, carry, or range pistols.

As the primary consumable wear item in the P229's slide assembly, the recoil spring manages slide travel and energy during the firing cycle. Installation requires field-stripping the slide and swapping the recoil spring onto the pistol's existing guide rod.

Sold as a single replacement recoil spring and made in the USA, the 1203721-R is specifically intended for the P229 platform.
