AH,
I have a 13lb ISMI recoil spring. I put it in a 2.0 Carry Comp.
I have to be 100% honest. I did NOT like the way it returned to battery just hand cycling the pistol… so I swapped it back to factory.
I never did fire it.
It was $16.20 direct shipped, purchased earlier this month.
I got caught up reading the 2.0 Comp was “over sprung”…etc.
Pistol shoots fine… but if you wanted it, I could save you a few bucks… your call.
