YVK Posted September 17, 2019 Share Posted September 17, 2019 I had feeding problems occur when I went down to 10 lbs on my Primary slide. No issue with 11 or 12. I use the former. Link to comment Share on other sites More sharing options...

That’s what I currently have in my Shadow 2 and it shoots flat. My load is 124 Gr PD JHP at about 130-132 PF. Link to comment Share on other sites More sharing options...

PGGUNS Posted September 21, 2019 Share Posted September 21, 2019 Had CZC do the slide cuts and plate system w/ DDP but now have the SRO. Had 11lb but started get light strikes. I shoot factory ammo, typically 124g or 147. Went to the 13 lb and no issues. Personally I like how the 124/147 returns to zero, not chasing the “flat” shooting gun but that’s just me.

mannyc Posted September 25, 2019 Share Posted September 25, 2019 Using 10lb with DPP, 147 gr /130 PF loads. Like it better than the 11lb, the 10lb to me shoots slightly flatter. Link to comment Share on other sites More sharing options...
Mitch_Hoff Posted October 4, 2019 Share Posted October 4, 2019 I ran a Wolff 9lb and really liked it. Link to comment Share on other sites More sharing options...
iBRKarma Posted October 7, 2019 Share Posted October 7, 2019 I've ran an 11lb in my S2 for several thousand rounds. No problems with OEM ammo or handloads around 130PF. My buddy Ethan H. #6 on the Carry Optics USPSA charts shoots an sp-01 Tactical(a little shorter) used an 11lb spring with no issues and recommended that for the S2 as well.
