Progressive Recoil Springs differ from common springs by having a reducing distance between coils starting from the middle of the spring to the last coil.

When pressure is applied, the spring functions in two phases:

• 1st: The first half of the spring, with identical coil distances, starts compressing from the beginning.
• 2nd: After the first half is fully compressed, the second half with reduced coil distance begins compressing.

Each coil increases the spring compression. Full compression provides maximum resistance and reduces recoil impulse.

Every Eemann Tech Recoil spring has a unique color for visual identification of the power value throughout its service life. All springs are painted with polymer heat-treated paint, which remains flexible throughout the service period and does not damage or dye the handgun internally.

• Installation of the progressive recoil spring for 1911/2011 by a certified gunsmith is recommended.

No fitting is required for most cases, allowing instant installation. However, some pistols may differ in production or be pre-modified, requiring assistance from a certified gunsmith for installation.
