ChrisTSO Posted June 26, 2018 Share Posted June 26, 2018 Ive got a cz 75 tso in a 9mm to shoot limited and I run factory winchester 124 gr fmj nato ammo through it and was wondering what would be the best recoil spring to run in it. The 11lb or the 13 lb? Any info would be great thank you! Link to comment Share on other sites More sharing options...
Postal Bob Posted June 27, 2018 Share Posted June 27, 2018 Whichever spring gives you the best/fastest double taps on target. Fyi, nato ammo is fairly hot compared to most target loads people are shooting. You'll probably need the heavier spring. But test both. Link to comment Share on other sites More sharing options...

I know they run a little hotter i just didnt know if anyone had experimented with it yet. Link to comment Share on other sites More sharing options...

George16 Posted September 24, 2018 Share Posted September 24, 2018 (edited) Between the two spring choices you have, use the 11# spring. I tested 10, 11, 13 and 16# (stock) and the 10# gave me the fastest reacquiring of the target. I’m shooting my reloads which consist of 124 Gr FMJ truncated cone from RMR with 4.2 Gr of Winchester 231 @ 1.102 OAL. Edit. I’m also using the stock thin buffer that came with my TSO.

Tampa-XD45 Posted September 25, 2018 Share Posted September 25, 2018 I also use Wolff springs but I've recently seen a lot of this company's 1911 parts on Ebay: http://klonimus.webstoreplace.com/ Their spring kit is only $19.99 for 7 springs. I have no experience using their products but the discussion on the 1911 forum seems to be pretty positive. 1911 Forum link You may find this "TSO 9 recoil spring" thread helpful: https://forums.brianenos.com/topic/265944-tso-9-recoil-spring/ Link to comment Share on other sites More sharing options...
CzViper Posted September 29, 2018 Share Posted September 29, 2018 For Nato ammo I would use the 13# spring.I bet after sufficient rounds your guide rod will start to take a beating.You could go lighter but at that point I would at least place the thin recoil buffer.
