I have a Gov. Model that was converted to Bullseye specs before I got it 20+ years ago. How often do I need to replace the spring? Current one is what came in the gun. I use this one for about 400+ rounds of mid-range loads a month. The only wear I notice is on the bottom lug which is flaring slightly from contact with the slide stop pin. Gun has at least 15,000 rounds through it since I got it. Brass is normally about 3-6 feet right rear.

I'm not real sure on Bullseye pistols because of the difference in the set-up. Maybe you could contact the 'smith that helped in the first place for more details?...

Hello Paul,

Recoil springs are relatively inexpensive. Wolff, the standard in gunsprings, has the 1911 recoil springs priced at $7.89 each. The springs come in a resealable plastic bag with the spring weight on it. You should also install an extra-power firing pin spring (the FP springs come with some of the recoil springs)

Wolff also has sets of different-weight recoil springs with the FP springs so you can dial-in the recoil spring weight to the load you are using.

If the ejected cartidge case lands 3-6 feet away, then you have the right spring weight. If the case lands further away, you need a heavier weight spring. If the case doesn't get ejected from your gun, you may need a lighter weight spring.

FWIW, When I was shooting "softball" target loads (185 grain LSWC) in my Government Model, I used a 14 lb. recoil spring. Sixteen pounds is the factory standard spring weight, if you want to shoot 230 grain hardball.

Good luck, and let us know how it works out.

Recoil spring- every shooting season or 5000rnds, whichever comes first. For your bullseye gun shooting match loads- 16lb spring max.

I change recoil springs every 3000 rds. Like one of the other guys said "springs are cheap".

Here is how I get the right recoil spring for a 1911.

First of all, I use Variable & Conventional weight springs when tuning a stock 5" pistol (no comp) and I only use conventional weight springs in a compensated pistol.

The next thing I do is to watch the pistols front sight. Watch how it returns to the target. If the sight stops above your original point of aim install a slightly heavier spring and try it again. If the sight stops below the original point of aim try a lighter spring and try again.

An 11 lbs. spring is a good starting point in a compensated gun and a 14 lbs. is a good starting piont in a stock gun.
