Possibly,
Im no stranger to tuning guns via recoil springs however, i am a bit of a stranger to very light springs, especially on a gun that has a supposed "light" slide. Im a Glock and CZ guy with only one 9mm 1911 and all of my guns generally run 11 lb springs. The only gun that ive ever tuned lighter than 11 lbs was that 9mm 1911 so im always a little skeptical when i find a gun that MAY need a lighter spring. I do know that alot of Limited shooters with light weight 2011 slides run eight or nine pound springs so perhaps i should have pulled my head out of my ass sooner and made the connection.
The thing that "got" me on this was the fact that im so used to 11 lb springs i just couldnt wrap my head around a lightweight slide potentially needing a lighter spring. All of the symptoms lined up with the need for further tuning yet something else seemed to be at play, ie coil bind, frame battering or god knows what else.
Here's to hoping Wolf gets me the lightweight springs before the weekend so that i can adequately test this.
