Steel Challenge

I have a Performance Center CORE 4.25 that I am going to shoot steel challenge with. my question, what pound recoil spring can I use to reduce the recoil a bit?( I believe stock is 16#) I will be using 124gr ammo. Or is it even necessary to change the spring?? Thanks

I ahootm115gr, and have never fooled with the recoil spring rate.

I have friends shooting 147gr 9mm, and they work fine with the stock recoil assembly, too.

I run the green Smith&Wesson recoil spring in my long slide...softens recoil and 100 % reliable.

I run a 13# ISMI recoil spring in all of mine.

11 is as light as you can possibly go, but really requires a lightened striker spring so that you won't push the slide slightly backward as you pull the trigger and compress the firing pin spring. They work in some guns, but not in others. And they need replaced every 5,000 rounds in my experience.

A 13-lb spring works in everything, and I couldn't tell the difference in felt recoil and sight tracking with 129 power factor 130gr & 147gr handloads. Pull the screw out of the end of the factory guide rod (1/4" socket with the rod in a vise) swap springs and reinstall the screw using red loctite, not blue.

M&P 9 & 40 Recoil Spring, 13# [1258] - $8.95 : Welcome to Speed Shooter Specialties

Beware - if you let someone with a limp grip (a small, inexperienced female for example) shoot a gun with light ammo and a floppy grip, they may have jam issues. Swapping back to the factory spring and slightly hotter ammo give the gun more slide velocity forward AND backward, and generally solves that issue. Experienced shooters won't notice... except that mousefart reloads don't result in the brass trickling down your knuckles as they were doing with the factory spring. It'll eject with oomph behind it again.

I shoot a 9Pro with 11# spring and 100gr projectiles with almost no recoil and no issues.

Note that if you change the recoil spring you also have to go to an aftermarket guide rod, AND you need to use the guide rod for the brand of recoil spring, ISMI recoil springs wont fit Wolf guide rods, I know that from personal experience, I have a Wolf guide rod and a variety of Wolf springs...and one ISMI spring, if I ever want to use it I'll have to order an ISMI guide rod.

Uh...

ISMI springs for the factory guide rod even better than the spring that came with it from the factory. Pull the 1/4 screw out of the tip, swap springs, and torque it back into place with red loctite.

That's why competitive shooting types use an ISMI spring and not the round-wire Wolff. You have to stick with a flat wire spring in order for the stock rod to work.
