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
Spring kit is great when testing different loads. 124gr ran well with the 10lb recoil spring and 17lb main.
Lighter springs will be fun to see how far you can go before any failures to feed.
Fast shipping, springs are great!
Great springs and both ends are closed so you don't have to file down the open end or which side you have to install it on your guide rod. Would definitely recommend it!
Ordered this recoil spring for my MAC 9 DS and I love it. Will also soon have a Springfield Prodigy and plan to change out that recoil spring as well. Love the product and plan to purchase more from this site!
I am glad I got this kit no guessing on what size spring to buy i needed a lighter spring for my prodigy comp for a load I made after testing I was able to use the 9 lb spring if your having problems like failure to feed or eject tuning with these spring will help
