My son recently bought a SA V-16 longslide. I know it shoots .45 acp, and it's supposed to shoot .45 super and .450 smc. I think you have to change a spring? Is this correct? We really don't know much about the super or smc. Are they the same, but just named differently or what? Hopefully someone can clear this up for us
Helpful hints on pushing back and strengthening the 2A:
The only difference between 45 super and 450 smc is the primer size. Last time I looked 450 smc was not available. Black Hills loads 45 Super. Check with Springfield about proper recoil spring rates. For ocasional use I use a 20# spring in a 5" 1911 for .45 super and 28# for regular use.
