trg Posted January 24, 2008 Share Posted January 24, 2008 I have a custom buildt 5" 1911 38 Super. The smith who buildt the gun tells me that he has installed a 10 lb recoil spring for factory ammo but if I want to shoot major loads I should replace it with a 12 lb. 12 lb for major sounds very light to me. Which spring do you recommend for pf180 loads? Link to comment Share on other sites More sharing options...

boz1911 Posted January 24, 2008 Share Posted January 24, 2008 Try an assortment but I would guess more like 14 lbs? Link to comment Share on other sites More sharing options...
XRe Posted January 24, 2008 Share Posted January 24, 2008 I would imagine that 12 would be fine. Why would you want to run Major PF loads in that gun? Self defense is about the only reason I can think of? Link to comment Share on other sites More sharing options...
superdude Posted January 25, 2008 Share Posted January 25, 2008 12 is a bit light for that heavy a PF. 14, maybe 16. it might depend on your load. slower gunpowders produce more recoil, and might require a stronger spring. i've had some 38 super loads that would run with a 20lb spring. scary.

Which spring do you recommend for pf180 loads? You might want to chrono some of the factory ammo. It will surprise you as to how hot it is. I would stay with the 10lb spring if it will run reliably and you dont mind the gun running a little faster slide speed. We shoot major power factor all the time with limited guns in 40 and I personally run a 9lb progressive spring. Never more than 10lb. I think you should shoot it and play with different combo's and then run what feels good to you and is reliable in the gun. Link to comment Share on other sites More sharing options...

dlp40cal Posted January 30, 2008 Share Posted January 30, 2008 put a 10 in and let rock Link to comment Share on other sites More sharing options...
trg Posted April 4, 2008 Author Share Posted April 4, 2008 I tried a 14lb spring yesterday. It cycled perfectly with major as well as minor loads. It also felt less punishing to the gun with the heaviest loads. Will the standard 10lb spring give me any advantages when shooting minor loads or should I just stick with the 14lb??

RangerTrace Posted April 4, 2008 Share Posted April 4, 2008 My Wilson 5" CQB, 38 Super came with a 12 pound spring. It was a blast to shoot with ball ammo, but had some minor feeding problems with Winchester Silvertips. I went up to a 14 pound spring (which is standard according to Wolff) and the problem went away. I have not shot any major PF loads through mine though. Most of the ammo I shoot is around the mid 140s PF. Link to comment Share on other sites More sharing options...

Good luck on the range Link to comment Share on other sites More sharing options...
buddy_fuentes Posted December 6, 2008 Share Posted December 6, 2008 My 9X23 uses a 14 lb. spring. I am running 124 grain JHP at a little over 1400 fps. and the 14 works fine. I have used heavier and lighter springs and the 14 seems to be the best, in my guns. Your Super would probably be fine with a 12.5 or a 14 pound. Good Luck Link to comment Share on other sites More sharing options...
E5MC Posted December 11, 2008 Share Posted December 11, 2008 I have a 13 in my 9mm. I guess I am over sprung. I'll try a 10# Link to comment Share on other sites More sharing options...
