darthdively Posted July 28, 2020 Share Posted July 28, 2020 So i'm trying to tune my CO P10f. i'm running a 13 lb flatspring from cajun. i really like how my gun returns to zero with the 11lb flat spring from cajun buuuuuuut.... that particular spring has problems. i can tilt the gun upward and the slide comes back a little or if i dryfire the slide will come back a little bit. i'm asking for the world with this question but have any of you found a light recoil spring that makes the gun function reliably? the run can actually run fine with the 11 lb spring. i had an issue at one point that i couldn't diagnose. slide got stuck in the forward position but not all the way and i had to ram the optic into the heel of my shoe, it was soft. got it loose and switched back to 13 and it didnt happen again. i have a couple spare 12 tanfo springs i can cut and tinker with. what have you all found to be the best in yours? p10 f, CO readyfactory magsRTS2 gen 4? lightened striker springeverything else stock thanks in advance.

Benevolence Posted July 28, 2020 Share Posted July 28, 2020 I believe if you’re lightening the recoil spring, you should be lightening the striker spring as well. At least in M&P’s they work against each other and can cause the gun to not fully lock up. I think glocks & P-10’s work that way to some degree as well. I’ve lowered my striker spring to a 3lbs without light strikes. Link to comment Share on other sites More sharing options...
darthdively Posted July 28, 2020 Author Share Posted July 28, 2020 I didnt think about the striker spring and recoil spring working against each other. makes sense. where did you get your 3 lb spring? is it a glock spring? i see some people are doing that.Sent from my SM-N950U using Tapatalk Link to comment Share on other sites More sharing options...
Benevolence Posted July 28, 2020 Share Posted July 28, 2020 Ya glock striker spring works fine. I’d get a few different weights for striker and recoil springs while you’re at it. Link to comment Share on other sites More sharing options...
darthdively Posted July 28, 2020 Author Share Posted July 28, 2020 what kind of recoil springs are you using? i got the 3pk tuner kit from cajun that came with a 11, 13, and a 15 Link to comment Share on other sites More sharing options...

CZ85Combat Posted July 30, 2020 Share Posted July 30, 2020 Is your recoil spring long enough? The P-10F takes a longer spring, P-10C spring might be short in the P-10F. Link to comment Share on other sites More sharing options...
mrvip27 Posted August 3, 2020 Share Posted August 3, 2020 (edited) I use the 15# gold and their guide rod. (CGW) They never used to offer anything below 15... Now i see they offer 11 and 13 as well.... BUT i am almost positive the 11 and 13 are shorter....the 15 and 18 are proper F length. The P series tuner pack shows working for the C and not the F. But yes, buy a HBI kit or the springs from CGW. Edited August 3, 2020 by mrvip27 Link to comment Share on other sites More sharing options...

darthdively Posted August 16, 2020 Author Share Posted August 16, 2020 just wanted to follow up. getting the zev 2lb striker spring seemed to have helped. more testing to be done. i have the 2 lb striker with 13 lb recoil spring. good ignition. no light strikes.

darthdively Posted April 4, 2021 Author Share Posted April 4, 2021 So another update, 2lb striker spring gets faulty half way through a match on winchester primers. Looks like up to 3 lb striker spring. Trigger pulls at a consistent 4 lbs . I wish I could get it lighter. I polished a couple points, it took away some grittiness. It breaks like glass now, but I want a lighter trigger. It looks like I'm with this 4lb for now just for reliability. the 2lb works good with federal primers. I hope this helps whoever reads this. Thanks! Link to comment Share on other sites More sharing options...
muncie21 Posted April 8, 2021 Share Posted April 8, 2021 I ran the light glock striker spring in my P10F and ended up with intermittent (1 or 2 every hundred or so) light strikes. Ended up putting the factory striker back in and the gun back in the safe until I have more time to tinker with springs and polish parts. Link to comment Share on other sites More sharing options...
dogtired Posted April 8, 2021 Share Posted April 8, 2021 I am still playing with mine but used a Glock flatwire 12# recoil spring and a 3 # striker spring from the Theta trigger kit. Link to comment Share on other sites More sharing options...
Benevolence Posted April 9, 2021 Share Posted April 9, 2021 Earlan357 did some modifications on the disconnector as well as got different springs for the internal FCG (trigger return springs?) and it changed the trigger quite a bit. That’s a bit more involved than just a recoil/striker spring changeout but just to show more can be done. I’m having a hard time finding his thread but it’s out there, maybe on czfirearms.us Link to comment Share on other sites More sharing options...
