Specs. Call for 16 lb.

 

Call them.

 

If you have the flat-wire recoil spring it is 17 lb. for the 5", if you have the round spring it is 16 lb. last I heard.

 

I've had a full size CQB for about 24 years. Speaking with WC many years ago they recommended an 18.5# recoil spring. That's all I have used and I have no problem with reliability.

My ammo of choice is my own reload which is a 200 gr. SWC (coated) over 5.0 gr. of Bullseye, which chrono at about 850 FPS. Wilson actually recommended this load in the owners manual I received with the pistol. It's proven to be very accurate.

 

Yes. I like the 18.5 lb. for all government model .45 acp. 1911's. 20 lb. for commanders. Wolff particularly. 9mm 1911's that is different with each gun.

 

I use 16 pounders in five inch 1911s, and 18 pound recoil springs in Commander sized 1911s.
Since springs work both ways; I don’t want any extra unnecessary force placed on the slide stop pin and frame holes as the slide’s going forward into battery. I also won’t have a shock buff in any of my pistols; don’t need them with properly sprung guns.
