9x 25 Dillon G20 guide rod spring upgrade

[Kenk]

So if I were to set up my G20 to shoot 9 x 25 Dillon, it looks like I may want to go with a heavier guide rod spring? If this spring upgrade is actually necessary, what  spring weight would be best?
Thanks

The 4 gen may be OK because the impulse of the 9x25 is different than the 10mm full power loads.
However I run the Non-Captive 22 lbs on the S&W 1006 and Glock 20SF and the 21 lbs dual springs on my G-29 for everything 40S&W, 357Sig and 9x25's

So in essence, your saying the factory spring setup on my G20 gen 4 is not likely to wreck anything running the 9 x 25 Dillon
Thanks so much!

I have a lone wolf tungsten Guide rod and the 17 lb and the 22 lb springs ( gen 3 with adapter) for my Gen 4 G20. I have not used the 22 lb spring yet. Waiting for my 9 x 25  Bar sto barrel  to be fitted to try it out. Does anyone have this setup for a gen 4?

I recently bought a Bar Sto 9x25 barrel for my Gen 4 G29. Who is fitting your barrel?

I run a non captive 19# with my LONGSLIDE Glock 20L and 9x25 LW barrel. Anything heavier is too much spring for that gun.
