Can anyone tell me the stock recoil spring weight for a Springfield Armory Trophy Match 1911? 18 or 16?

Stock recoil spring for a 1911 is 16lbs. In 1911s I typically run 14lbs for IPSC major Powerfactor loads.

I replaced both the springs in my TRPs with 18.5lbs spring and have been outstanding, My Dept armorer advised me to stay with 18.5s. Im waiting back for a reply from the springfield armory custom shop. Thanks for the heads up

For factory duty ammo (+p type stuff) I would stay with the 18.5#, but that is too much spring weight for a normal 165 PF uspsa load. It would be too stiff a spring and would either not function properly or the spring would act like a pogo stick when the pistol cycled. Like another member said, for uspsa major loads a 14-15# spring is just about perfect. The pistol will shoot much flatter that weight spring in it.

I have moved up to 18.5, the muzzle flip is a slight issue as well as casings being thrown 20 feet over the shoulder. Maybe that will tame the dragon.

Since Springfield Armory uses a stout Mainspring to ensure sufficient titanium Firing Pin hits, I thought they generally installed a lower poundage Recoil Spring to make up the difference.

If you try an 18 lb Recoil Spring in your Springfield, be sure to try it out and make sure the brass is being thrown clear of the gun - not dribbling out.

Thanks, Come to think of it the brass flys out about 15 feet to my right

Recoil spring - sa

Springfield Armory

Operation and Safety Manual ( Should have been with your Pistol )

Page 50

Part No. 2h Pl0030 Recoil Spring ( 16 lb. )

I have 2 a 9 mm SS Loaded & .45 TM have run 13s, 14s, 15s, 16s in them according to the type ammo being used. Note- neither wants to run right with a buffer. For what it's worth.

Be SAFE,

Perry

guys a lighter recoil spring, to some extent, will make the recoil feel less in your hand. Those heavy recoil springs your using to "tame the muzzle flip" is also causing the gun to be pushed back into your hand harder instead of just the slide moving back. It takes more force to over come those heavier springs.

AKA the pogo stick effect... A lighter recoil spring will, as Cory stated, make the pistol recoil to actualy magnify and not shoot as flat as it could.
I still say though, if you shoot factory ammunition, stay with a 16# recoil spring. If you reload, and shoot 170pf ammo a 14-15# spring would work great.
The end goal is to have the gun shoot as flat as possible. The brass SHOULD be ejecting from 4-6' from you (in a perfect world). If the brass is just barely plopping down next to you, the spring is more than likely too strong, if it flings out 11+ ft it's probably too light. That is one of the nice things about a shock buff. It will tell you if the frame is being battered by the slide. Try a buff when you install a lighter than normal recoil spring. If it is shredded after 50-100 rounds the recoil spring is too light. If it looks untouched or slightly indented then bingo you are good to go.
