Our in house ProArmory branded spring kits are made from the finest quality spring wire and heat treated correctly. We then extensively tested them in our practice and competition guns. In this kit we have included three recoil springs and three main springs.
The recoil springs range in weight from 9 through to 11 lbs. as do the main springs.

We have included the three different recoil springs for the following reasons:
a. So you can create a custom feel to your gun depending on your reloaded or factory ammo, and grip strength.
b. So that if you’re running optics you can preserve them by running the heavier 11# spring.
In relation to the main/hammer springs:
a. We have no control over what hardness primer you are using in your reloaded ammo, there are also issues with supply, so you can start with the 9# and if you have any light strikes move up to the 10# or 11#
b. If you are using factory ammo you can again ensure you have enough energy to light up the primers whilst enjoying the softest double action possible for given primer hardness.
Springs color coding:
Yellow dot is 9#
White dot is 10#
Red dot is 11#

If you are not familiar with the complete disassembly of your pistol we recommend that the installation is done by a certified gunsmith.
