Nemesis Lead Posted March 9, 2016 Share Posted March 9, 2016 Hi All, I am setting up a 1911 for competition. What weight springs do you all use for your recoil spring and mainspring? The gun is a Wilson Combat 1911 in .45 ACP. Thank you all in advance! Link to comment Share on other sites More sharing options...
ogiebb Posted March 9, 2016 Share Posted March 9, 2016 for 45acp I use 14# ISMI and a 17# Hammer Spring Link to comment Share on other sites More sharing options...

Steve RA Posted March 9, 2016 Share Posted March 9, 2016 17lb main spring and 14lb recoil spring - both wolff springs. Link to comment Share on other sites More sharing options...
jtrump Posted March 13, 2016 Share Posted March 13, 2016 14lb Variable recoil spring WOLFF 17lb Mainspring WOLFF Dawson extended steel firing pin " even with federal primers" This is with 200g SWC at 169PF, no signs of beating the gun up at all.

Yeti Posted March 13, 2016 Share Posted March 13, 2016 Govt in 45acp..... 19# main paired with a 14# straight rate recoil spring. The Wolff 14# variable is an outstanding do-all choice, though. . Link to comment Share on other sites More sharing options...
terrydoc Posted March 13, 2016 Share Posted March 13, 2016 What about some recommended springs weights for 9mm? Link to comment Share on other sites More sharing options...
Steve RA Posted March 13, 2016 Share Posted March 13, 2016 17Lb main spring and 10lb recoil spring - also might try a 9Lb and see which you like best. Link to comment Share on other sites More sharing options...
terrydoc Posted March 13, 2016 Share Posted March 13, 2016 I'm presuming that's for 9mm Steve? Link to comment Share on other sites More sharing options...
DagoRed Posted March 13, 2016 Share Posted March 13, 2016 So all you guys using 14lb recoil, is that with major power loads? I just put a 16.5 variable in mine w a 19lb main. I read somewhere that you can tell from where your brass is landing if you have the recoil spring weight right but can't remember what the guidelines were. I'll have to do some more playing. I just put this one in though so I think I'll set my other 1911 up w the 14 and shoot side by side. Red Link to comment Share on other sites More sharing options...
Sandbagger123 Posted March 13, 2016 Share Posted March 13, 2016 I have freinnds that use 12 to 14 pound recoil springs in their 1911. Seeing that the 45 cap generates less pressure than the 40 that a lot of people use 12 pound recoil spring I don't think it's gonna hurt your gun. I have been using a 10 in my 2011 40 and have not seen any issues in 10k rounds I have through it Link to comment Share on other sites More sharing options...
Foxj66 Posted March 13, 2016 Share Posted March 13, 2016 I am using a 14lb Recoil and 17lb Main, both ISMI my gun didn't like a 12.5lb recoil with a 19lb mainspring. I also use a Tungsten guiderod Link to comment Share on other sites More sharing options...
Steve RA Posted March 13, 2016 Share Posted March 13, 2016 Terrydoc: Yes, the 17Lb and 10Lb or 9Lb is/was a 9mm suggestion. 17Lb and 14LB was for .45 ACP. Link to comment Share on other sites More sharing options...
twodownzero Posted March 13, 2016 Share Posted March 13, 2016 I use a 19 lb main/14 lb recoil for my .45. 17/12.5 for the .40 cal 2011 with a lightened slide 17/10 for the 9mm. Link to comment Share on other sites More sharing options...
terrydoc Posted March 13, 2016 Share Posted March 13, 2016 Does anyone know what factory main spring, recoil spring weights usually are for 9mm? Link to comment Share on other sites More sharing options...
Aircooled6racer Posted March 13, 2016 Share Posted March 13, 2016 Does anyone know what factory main spring, recoil spring weights usually are for 9mm? Hello: Usually around 9-11lb for recoil springs and 19-23lb for mainsprings. Since you are asking about 9mm I use 9lb ISMI recoil spring and a 17lb ISMI mainspring. For 40 I use 17lb mainspring and a 14lb recoil for major and 12.5lb recoil for minor. For 45acp I use a 14lb recoil and a 17ln mainspring. Thanks, Eric Link to comment Share on other sites More sharing options...
