I know the recoil spring topic has been discussed a lot lately, but here's another question. Can I use the same lb recoil springs in my Ultra, Compact and full size Kimbers? If not, what ones would you recommend for each size? I use 230 gr ammo in all my guns for practice but in my Ultra Carry I use 165 gr Hydra Shoks for SD only.
Thanks in advance!

They definitely take different weights and sizes.

You want the same feeling? It's a little Apples/Oranges I think

Factory 5" is 16#
Factory 4" is 22#

I use a lighter spring (14# ISMI) and a Shok-Buff in my 5", but left the 4" alone.

I know people that go to 11# and 12.5# in 5" guns, but mine would not feed reliably that light.

I don't know anyone (but less people shoot these too), that's changed thier 4" spring weights.

Others, I'm sure have experimented

Two More...

I forgot to add two more Kimbers... my 9mm and 40S&W, both 5". For you that have the 9mm, did changing the spring to a smaller lb fix the problem that some of you were having? Thanks again.

Dumb question here, but what do the number's for the springs mean? Is it a grading scale like wire guages?

"#" is the symbol for "pound" as in weight; in this case it refers to the spring's loading.

I don't know the exact formula or how it's determined by the mfrs, but it should be easy to find either on the mfrs' web sites or an online engineering reference site.

After snooping around this fourm before buying my Kimber Stainless II a couple years ago, I picked up on swapping out the standard recoil spring for an 18# spring. I have never fired it with the original spring now that I think about it.
