This recoil spring kit includes five springs in 1lbs increments from 7lbs-11lbs for tuning your guns performance to the specific ammunition and parts you are using. They are manufactured from 17-7 stainless steel and are designed to fit 1911 and 2011 4.25"-4.4"
These springs are manufactured by AQS the factory that makes springs for Noveske, Apex, Sig, CMMG, POF-USA. We lucked out and our shop just happened to be ten minutes from their factory.
The springs are spray painted in a color code to identify their weight, we put green and red at the opposite end of the weights so color blind individuals can tell them apart by testing tension in their hand.
7lbs - Green
8lbs - Blue
9lbs - White
10lbs - Yellow
11lbs - Red
Excellent product and quick delivery
Great product works perfectly, I would definitely recommend it.
Great customer service and advice for a kit that provides lots of option. Thank you
Ordered these for testing my Staccato P with the Threat Cadre comp. Went with the 9# out of the gate and so far it is a dream to shoot, probably almost half the recoil of a stock Staccato and using a lighter 17# mainspring/hammer spring. Thanks for a solid set of springs!
Springs worked perfectly just what I needed
