Recoil spring long slide

What recoil spring would you use for a long slide with bomar rib? Thanks

I ordered a set from Wolff and cut to length as needed on the one that worked for each load.

Recoil Springs - 1911 Longslide Modifications

Longslide modifications to 1911 pistols often require a longer than normal recoil spring. Wolff longslide recoil springs are designed for use in pistols with recoil spaces up to 3" (when slide is in full recoil position). 5 different strength recoil springs are available denoted as #1 thru #5. Due to the custom nature of these modifications, no rating for these springs is possible. The #1 recoil spring is the strongest and #5 is the lightest. Fitting of these springs is required. Professional installation suggested.

I have shot longslide for decades. I’ve never liked the Wolff springs for the longslide because they require cutting down and messing with loads. I ha very use standard springs with standard recoil spring plug. I used 12# for my lighter loads and 14# for my heavier loads. EGW does make a recoil spring plug that converts a 6” slide to a 5” length recoils spring.
So you have several choices.

Lots of folks make a recoil spring plug for 5" springs... its the way to go. Standard or reverse plugs are available.

Here is a standard length spring and longslide recoil spring calibration pack below it. Fun!
