Orbit Posted July 27, 2018 Share Posted July 27, 2018 Friends, I am not sure if this question of mine is already discussed but anyway i would like to ask your experience and opinion. I started reloading for 9mm pistol: 1. 147g Campro with 133pf TG 2. AOL of 1.12” Before i am using the 13lbs recoil and 13lbs hammer spring for both cz shadow 1&2. It evolved to 11lbs and 13 hammer spring and NOW 8lbs recoil and 13 lbs hammer spring. Sometimes i experienced slow motion of the slide when going back to battery. My questions: 1. Will it wear down my pistols? 2. Is this a good mix? Any comments or recommendations? Link to comment Share on other sites More sharing options...
m-cz-shadow-2 Posted July 31, 2018 Share Posted July 31, 2018 I can't speak if this will wear it down. However I use an 11.5 hammer spring and an 11 lb recoil spring. I am shooting 135 Gr Acme with 3.3 Gr of Aliant Sport pistol with OAL of 1.12". For me the gun cycles flawlessly and the DA pull is very nice at right around 6 lbs. My power factor is right around 128,000. This is at 1650 ft above sea level and with around 20% humidity and 105 F outside. Link to comment Share on other sites More sharing options...

uewpew Posted August 23, 2018 Share Posted August 23, 2018 I also run 11lb recoil (with plastic buffer) and 11.5 main. 124gr bullets @ 132pf. Approximately 30k rounds through this setup and slide stop is in good shape. Link to comment Share on other sites More sharing options...
mauk517 Posted October 10, 2018 Share Posted October 10, 2018 I was wondering what primer do you guys use and if there are ignition problems on the 11lb springs. Link to comment Share on other sites More sharing options...
mauk517 Posted October 10, 2018 Share Posted October 10, 2018 I run 11lb recoil and 13lb hammer. Link to comment Share on other sites More sharing options...
mauk517 Posted October 10, 2018 Share Posted October 10, 2018 I have experienced some of the times that the slide comes back slower than usual but very few. I was wondering if my recoil spring is wearing down but still works fine after that. Link to comment Share on other sites More sharing options...
jripper Posted October 25, 2018 Share Posted October 25, 2018 I'm running a 8.5 lb hammer, with and 10 pound recoil spring. Do not have any problems with slide cycle. Link to comment Share on other sites More sharing options...

I load on a 650, so I seat them as hard as possible, but I don't really know a depth. I've never had a misfire with federals and this set up 4 different guns.

wtturn Posted November 5, 2018 Share Posted November 5, 2018 I bought an 8# and a 9# Wolff recoil spring to test in my S2. I didn't even bother trying the 8 after I tested the 9 and it felt like the slide stayed pinned at the rear for decades in recoil. Seriously, it felt like ages that the front sight was just floating out in the universe with no plans to return home. This was with 125gr loads at 132PF. I went back to the 11#.

jripper Posted November 5, 2018 Share Posted November 5, 2018 I used the 11 a long time, but when I started shooting carry optics, I really see the dot dropping down upon return from recoil The 10 makes it just a less drop when the gun comes back done. I like it with the production/open sight set up better also. And I don't feel like I'm waiting for the slide to close. Link to comment Share on other sites More sharing options...
magpulled Posted December 15, 2018 Share Posted December 15, 2018 I’ve tried 9lb recoil springs in my shadow 2s and they last about 200 rds before the slide starts cycling really slow when going into battery. I use 10lb springs now and thousands of rounds later it’s still good. So imo 10 is probably as low as you can go without issues. Link to comment Share on other sites More sharing options...

If you have a 9lb recoil spring but have a heavier hammer spring, then the cycling will be much slower as the slide needs more effort to push the hammer back.

Yeah, I use an 8.5 lb hammer spring in my s2’s. Not sure why the 9lb springs I tried didn’t last. Link to comment Share on other sites More sharing options...

reverse_edge Posted February 18, 2019 Share Posted February 18, 2019 11.5# HS Generally been running 10/11# recoil springs, but wanted to experiment with lighter springs. The 8# feels nice, but my thumb brushed the slide ever so slightly and it felt like time stood still while I was waiting for the gun be ready to fire again. I think I'll stick with 10# Link to comment Share on other sites More sharing options...
