Recoil spring weight for long slide / iron sights

Hi,

I was wondering what spring weight would be suggested for a 6" slide / iron sights shooting 4.2 grains Titegroup with 200 grain lead SWC.

Thanks,
Dave

Dave,

Wolff does make springs for a 6" gun, but they are a custom fit.  They're rated from 1-5, 1 being the strongest and 5 is the lightest.  They sell a kit,

13191

COLT 1911 LONGSLIDE RECOIL CALIBRATION PAK

35.99

I would start at #3 and adjust as needed from there.

Excellent, thank you KC.  I appreciate the help,
Dave

If you have a full length guide rod sti makes a plug for a 6" slide that will accept standard 5" springs. That's what i use in mine.
