I looked but didn't see this topic addressed yet, so I thought I'd ask.



Has anyone done any playing around to see what the heaviest recoil spring will still reliably cycle 115gr 9mm?



Just curious, ya know

Thanks!

Why do you want to put in a heavier recoil spring?

Eat up any excess energy expended from the shot. The stronger the spring, the more energy it takes to compress it. This then (in theory) minimizes recoil and muzzle flip.



I was just curious about this

I will have to disagree with you in using a stronger spring with standard PF loads. Given equal power factors, the stronger spring will induce MORE recoil and flip than a lower strength spring.

and the Brian Enos Forum Spring Section.

Touche'!

Hadn't thought of that part of it. Fair enough. Moving on. Nothing to see here!

Looks like the answer is to match them to your load.



When shooting the stock spring I shoot the 2nd shot high in a double tap, and after switching to the 15lb spring, I shoot about centered with both shots.

Jester,



What ammo were you running with the 15lb spring?

 

[Jester]

165+ powerfactor 155Gr reloads, meaning about 1075-1100FPS or more.



Winchester White box is 165 gr at about 1050 FPS if thats any help.



Remember this is subjective, I may grip my pistol different, causing slower/faster recovery making this spring the one I need. I only tried 2, and this one works great for me, I think I got lucky.
