Decided to finally replace the original recoil and firing pin springs on my SR1911. The gun was still running 100%, but due to it's age and the amount of rounds I've put through it, I figured it was due.
Here's how the new ones (lower) compared to the originals...
While the new firing pin spring is just a touch longer than the original, it's the recoil spring that really surprised me. Since I don't have a tester I can't measure the actual rates, but the differences in free lengths point to the new one being a heavier rate.
Since I've had zero issues with the way the gun runs, even while messing around with various reloading recipes, I decided to stick with the factory parts. Ruger shows the recoil spring as an 18# weight. I had a 20% off coupon due to another recent Ruger purchase......so it made the springs stupid cheap to buy.
