Why not the stock spring ?
figure it might help the frame out from the 357 recoilwhy not the stock spring ?
The G-19, G-23, and G-32 all use a stock 18# recoil spring. The 9mm and .40S&W cartridges are both 35,000 psi pressure where the .357sig is 40,000 psi.figure it might help the frame out from the 357 recoil
Thanks for the help I may try a 20# springThe G-19, G-23, and G-32 all use a stock 18# recoil spring. The 9mm and .40S&W cartridges are both 35,000 psi pressure where the .357sig is 40,000 psi.
I use a Wolff 20# spring and stainless steel guide rod in my G-32. It's noticeably reduced the muzzle flip so I assume you'd get the same results from essentially the same gun.
And as you say, the stiffer spring helps reduce the frame battering. You should be able to use the same spring assembly for the .40S&W.
