Default Spring tricks don't work

Folks, I am new to this forum even though I have been a S&W revolver and pistol guy for over 40 years. My journey with the Slide Fire and the 15-22 led me here.

I have the Sport. I am using Mini Mag and Winchester Super X. Both 40 gr. CMC 3.5 curved installed. I got very inconsistent results, mostly light to no primer strike, with the stock firing pin spring. I tried the 1/8" off the stock spring with no better result. Same with the McMaster-Carr spring. The 15-22 has fired well with all 3 tries in semi mode. Good primer strikes and no problems. Only when attempting the SF mode did the action fail to cycle with light or no primer strike. It seems to me that it is not a recoil issue since semi works fine. Nothing can be done with the hammer spring since I am using the drop in CMC. Do any wizards out there have any additional advice.

Thanks. Bill
