Warrior75 Posted March 16, 2022 Share Posted March 16, 2022 What rate pound spring are you using? My load is 173 pf. I was using whatever spring came in the gun from factory with the buffer. It seemed to shoot pretty flat. I was told factory spring was 16 lb. I bought a couple Wolff 16 lb. springs for replacement. I have yet to shoot it with a replacement spring. I am curious to what other are using. I know this all depends on the load you are using. Link to comment Share on other sites More sharing options...

Ive actually been toying with the DPM systems 3-spring setup. You can definitely tweak the feel of the recoil impulse with it. I already shoot 200 rounds a session as it is, but it definitely takes a pile of ammo to get the feel right. I was using the 16lb with the factory guide rod, then moved to a 15lb. Now Im on the DPM setup CZ 75 SP-01 Shadow/Shadow Line-Tactical-Phantom & TS Orange – DPM Systems Technologies Ltd Edited March 20, 2022 by Guitarmageddon Link to comment Share on other sites More sharing options...
CC3D Posted March 20, 2022 Share Posted March 20, 2022 Currently using the lightest spring that was included with the TSO (11 pounds I believe) and the thick buffer. My loads are also at 173 and I can confirm that recoil impulse is much better with the lighter spring, return to zero is much better as well. I was getting some muzzle dip with the heavier spring (gotta remember they come from the factory ready to run factory ammo with a PF of more like 200), switching to the lighter eliminated that completely. Try out the lighter ones and see what you think, your brass will be landing 3 bays over just FYI. Link to comment Share on other sites More sharing options...
Runnin2live Posted March 20, 2022 Share Posted March 20, 2022 I also use the lighter #11 spring in mine. Mine felt more sluggish with the heavier spring. Link to comment Share on other sites More sharing options...
Warrior75 Posted March 21, 2022 Author Share Posted March 21, 2022 I shot a match Saturday with with the 16 lb spring. I did not get a chance to test it beforehand. The gun ran fine. (Other than I had 2 light strikes. Primers looked like solid hits.) It did not seem to dip when going back into battery, but I will try some lighter spring and see if it is better. Thanks for the replies. Link to comment Share on other sites More sharing options...

What I did was take slow mo of the all the different springs, watched them back side by side, and picked the one that had the best return to zero.

I did try a 12 lb. spring vs a 16 lb. I did not care for the 12 lb. Felt like the sights raised more. I ended up trying a 14 lb spring. Shot a club match last week. As I prefer the feel of it, over 16 lb. I will have test them again with video. Link to comment Share on other sites More sharing options...
