Recoil Springs And The 1911 ?
« on: May 04, 2010, 10:43:29 AM »
Some time back I purchased A Wolff recoil spring "kit" for my Colt Gold Cup. It comes with a total of 5 recoil springs, and 3 firing pin springs. My intention was to put a stronger spring into my Gold Cup so it wouldn't beat the crap out of itself when I shot hardball through it. The recoil springs are a "standard" 16, 18 1/2, 20, 22, and a 24 pound weight. The 3 firing pin springs are "extra power" type. They're still unopened in the package, and I never messed with them. Now that I purchased this Kimber my interest in 1911's is somewhat rekindled.

What spring weight gives the most reliable performance with stoutly loaded hardball, or the +P+ self defense ammo? All the "instructions" say is, "Start with the highest load rating and work down until the desired slide operation is obtained." What weight recoil springs do you guys run in your 1911's? I've shot hardball in my Gold Cup with the standard spring with no ill effects, but it's probably not the best idea. From now on I'll shoot the hot stuff in my new Kimber, and leave the light loaded target loads for the Gold Cup. Will the hot loaded self defense ammo run a 24 pound spring, or should I start lighter? I'm hoping to learn here from others who have experimented a little more than me. The fewer times I have to take the gun apart and change springs at the range, the better.

They also talk of the springs possibly requiring "fitting"? I'm assuming they mean cutting them to length to fit, but that would change the power and weight of the spring itself??  Ideas?  Bill T.

Mine is a 18 lb. but its a Gov 5 inch you really have to shoot a few to tune it in. Key is the slide works without any FTFs or stove pipes.

The only time I have ever had problems with cycling problems with my 1911's was with reloads. I was using 5 gr. of Accurate #5 pushing a 230gr RNL bullet (my old target loads). It was a mild loading and it sometimes failed to cycle reliably with heavier springs.

For the most part, I've never had problems (spring related) with factory rounds and I have generally used 20 or 22 pound springs in my 1911's. I ran a 24 pound spring for a while, but couldn't tell any difference.

That being said, YMMV, of course.

I use an 18.5# variable rate spring. A 20 or 22# would probably work as well for everything except light target loads. The 16.5# variable rate would be the same as a standard 16 pounder. I would try one of the heaviest springs and see how it works.

P.S. When I bought a Para widebody kit 20 years ago it came with an 18# spring and said not to use anything lighter.

For a .45 acp, SD or Duty pistol, I use 19 or 20lb, that extra punch works to give hollow points that little extra, to jump the ledge into the throat of the chamber, But the resistance of the slide on recocking the hammer, is part of the equation as well, as the slide moves rear ward, it must recock the hammer, against the hammer spring, ( I don't recommend lightening the mainspring ) unless your going full game, and will not use that pistol for SD or Duty. But you can make this operation, less resistant, rounding the firing pin retainer and slide on the bottom helps, plus polishing the hammer face where the slide and hammer come together,  and watch for the slide overcocking the hammer, too much movement, beats the hammer hooks to death, sometimes removal of metal from the hammer face at just the right spot, makes the resistance much lighter, and you can feel it when operating the slide.

"Firearms stand next in importance to the Constitution itself. They are the American people's liberty, teeth and keystone under independence. The church, the plow, the prairie wagon and citizens' firearms are indelibly related. From the hour the pilgrims landed to the present day, events, occurrences and tendencies prove that, to ensure peace, security and happiness, the rifle and pistol are equally indispensable. Every corner of this land knows firearms, and more than 99 and 99/100 percent of them by their silence indicate that they are in safe and sane hands. The very atmosphere of firearms anywhere and everywhere restrains evil influence. They deserve a place of honor with all that's good. When firearms go, all goes. We need them every hour."

The only one I can say for sure is my Rock Island Armory 1911, and it's a Wolff 18 pounder. The others, I have no idea.
