You'll find what works for you once you've got your hands on the carbine. I'm sure there are replacement recoil springs out there, just like for the Camp 9 and Camp 45 carbines.If you'll be at the reunion in April I will take you up on that. Thank you.
My understanding is that .44 special may not cycle the carbine properly so I was thinking a 44 Mag revolver so I could use the same cartridges in both. I need to look into that.
I like the fact that .44Specials are subsonic, so if the 77/44 becomes integrally-suppressed, that'll be a perfect marriage.
