Help me with recoil spring... under or over sprung?

So what are y'alls thoughts on video... does it appear to be sprung efficiently?  It feels good but may go down to a 9 just to see what the results are.  

 

It is a 9 Major with LSI comp.  170.5 PF    115 MG   8.4 HS6

10lb Var Wolff recoil spring

 

Thanks for your help!

Yeah, the nose is dipping when the slide closes.  You might try 9 and 8 variable, maybe even 7 variable.  Depends on how heavy the slide is and how well the comp works.  Trial & error, basically.

 

I'm using 7# in my 9 major and 38sc, works best for me.

There's a big dip on recoil, try going down a lb or two on recoil spring and up 2-4 lb on mainspring.  You'll also want to try opposite geometry on the firing pin stop as you currently have as part of the testing. I.e. If it rounded, try a steep slope cut with all springs.  You'll see more difference in slow vid that in the dot initially

Yep looks like it is oversprung, I would stick the 8 in and try it. I tried a 9, 9 variable, 8, 8 variable and then a 7 and there was no dip at all with the 7. Good luck!
