Someone has tried 16 1/2 and 17 1/2 Wolff variable power recoil springs? Are they satisfactory for normal power (factory Ball ammo) ammunitions, and how well they compare to standard Colt 16lbs recoil spring?
I've used both 17.5 and 18.5 Wolff variable springs. My gun has been flawless with both. I've also used 18.5 standard springs without a hitch. I do run into trouble with Shok-Buffs, though. Neither of my guns like them very well.
