EFK or Wilson for a 1911 10mm?

[Demitrios]

I've purchased a used 1911 chambered in 10mm a few months ago and I've wanted to change out the recoil spring since I don't know how many rounds have been through it. Since I've started reloading I've decided that now it's more prudent that I take care of this sooner than later, rather than beat up the gun. I've been looking at #22 springs by Wolff and I came across Wilson's Shock Buffer System and I've heard good things about EFK as well.

In short, what do you guys think would be the best options in lightening up the battering my gun will be going through as long as I'm shooting it?

On my 10mm DW I've went with EGW oversized Firing pin stop, 23 lb mainspring and 20 lb recoil spring. I'm not a fan of shock buffs at all.

What Techmike said. I have the same set up on an old Dan Wesson Razorback.

I have used Shok Buffs for many years in my competition 1911s ---- I change them every 3000/4000 rds. and change the recoil spring every 5000/8000.
