rustychev Posted April 28, 2016 Share Posted April 28, 2016 What recoil spring weight should I start with for a 5" 1911 in 40sw with a PF of 131 stock is 19 I think. Thinking of trying a 16 as I have a few for my 45s. Sent from my C6750 using Tapatalk Link to comment Share on other sites More sharing options...
cnote Posted April 29, 2016 Share Posted April 29, 2016 I would buy a pack and experiment, at minor PF I run a 9 lb for 9mm Link to comment Share on other sites More sharing options...
mach1soldier Posted April 29, 2016 Share Posted April 29, 2016 Start at 12 and work down. I wouldn't run any higher then that. Link to comment Share on other sites More sharing options...
MKitzmiller Posted April 29, 2016 Share Posted April 29, 2016 Step one is determining exactly what spring # you're running now. Step two is buy a recoil spring calibration kit and step down slowly from your stock spring, (19 sounds super heavy). Step three is back to step one with your mainspring.. Mediocre advise at best.

Yeti Posted April 29, 2016 Share Posted April 29, 2016 I run a 12# recoil with a 19# main for 170PF with an Alumabuff. I agree with Mach1, you should try a 11# or 10#. What mainspring are you running now? It is likely too heavy also. Link to comment Share on other sites More sharing options...
rustychev Posted April 29, 2016 Author Share Posted April 29, 2016 Not sure what the main spring is but it is the one that came with the gun. I have not changed any springs as I shot major for the most part but want to start shooting SS minor with this gun. It may run with my minor load but I don't think so. Had to drop the recoil spring 3 pounds on my glock 22 to run my 40 cal minor load Link to comment Share on other sites More sharing options...
rustychev Posted May 20, 2016 Author Share Posted May 20, 2016 Ok finely got the range today to do some testing. First I did call sig and they say the stock spring is #19 but it is a flat wire and is 4 coils shorter than a round wire #16. Also to me when I put in a #16 it feels heavier than the stock spring. I put in a #16 and it runs my major load great with lock back even limp wristed but will not lock back my minor load at all. Worked my way down to #12 and it works for my minor load with every thing but a grip just hard enough to make sure I did not drop the gun. Minor load is 135 PF.

JD45 Posted May 21, 2016 Share Posted May 21, 2016 Listen to these guys. I shot a .45 at 175PF for years and used and 12lb. recoil spring and 19lb. mainspring. Yours is too heavy. Link to comment Share on other sites More sharing options...
rustychev Posted May 22, 2016 Author Share Posted May 22, 2016 I like the way it feels with a 16 and 12 and it runs so why exactly is the 16 to heavy? Link to comment Share on other sites More sharing options...
JD45 Posted May 22, 2016 Share Posted May 22, 2016 How many rds do u shoot per month? And what are your Bill drill times? It takes a lot of shooting to see the difference. Link to comment Share on other sites More sharing options...
rustychev Posted May 22, 2016 Author Share Posted May 22, 2016 about 500 rounds a month and a cold bill drill is 2.5 to 2.6 with a draw of 1.5 to 1.6.at 7 yards. I need more work on my draw than my splits as far as shooting speed goes Link to comment Share on other sites More sharing options...

BallisticExpansion Posted June 13, 2016 Share Posted June 13, 2016 I am using a 10lb wolff conventional in my Edge with major PF in limited. I have an 11lb that I plan to test some more. I like to do several exercises to feel and see the difference in them. Set up an open target at 20/30yds. Pick a spot in the A zone and shoot watching the sights recover each time and making note of how high they go and if they dip when the slide goes forward. You can put several strips of white tape on the target to help you gauge the movement in the gun and put a small circle for your "bullseye" if need be. Do some 6rd bill drills at 25-35yds. Use a clean target. Record your times and hits. Do 6rd bill drills at 7-10yds. Again use a clean target. Lastly you can put a 5" dot on a target. Stand 7yds away. Start with your gun aimed at the dot. Fire 2 shots at the same speed you normally would on a target that close. Your first hit should be in the dot every time. If your second hit is above the dot your spring may be too light. If it is low you are using too heavy of a spring. Hope that helps. Link to comment Share on other sites More sharing options...
lucas Posted June 16, 2016 Share Posted June 16, 2016 I run a 12# wolf spring in my 40 with a 180gr @170 PF based on bill drills. For my 9mm, based on Bill drills, I run a 8# 147gr @ 130 PF. If I was running a 40cal @ 130 PF , I would test Bill drills with the 12# spring to start going all the way down to 10,9,8 pound springs , to see which poundage tracks the best.

IFlynn Posted May 2, 2017 Share Posted May 2, 2017 12lb wolf variable spring has always been fantastic for me. I've never gone less in 40sw. Link to comment Share on other sites More sharing options...
