Recoil spring help for cts 9mm - 147gr w/ sp01 frame
« on: August 07, 2017, 06:39:31 AM »
I picked up a cz75 cts-lsp a few months ago then put the slide on my sp01 frame.
I think I've settled on 147gr reman loads from freedom munitions.
with the regular 75 frame the gun recoils a bit more, but doesn't dip after recoil.
with the sp01 frame, the gun recoils less, but dips a bit after recoil.

for the fine folks at CZC - the ls-p shipped with an 11# TS recoil spring, right?
i would like to use the sp01 frame, stay with the 147 gr bullets, and loose the dip after recoil.
What do you suggest?

Recoil springs are pretty subjective. If you find it dips after recoil, then you need to use a lighter recoil spring. I would suggest buying a range of springs and trying them all.

I use a 10# in my Shadow 2 while other people use 8# or 11#.

I also use 10# springs with my Longslide.

10# - hmmmm... with what load?

I just got in a CGW 11# yellow - and it feels exactly like the spring that came with the CTS from CZC - which I'm thinking was a 11#er.

I also ordered some 135gr bullets from Freedom Munitions.

here is an experiment:
11# + 135gr vs 10# + 147gr
which load will balance out and not dip.

I really need to do some slo-mo video
