I recently purchased a 20# bolt mainspring for the '03 Springfield. I was convinced for some reason, that the issue mainspring was 20#. I find out that it was 16#.
Yeah I should have looked, but thats what I get.

The question is will this affect performance or puncture primers?? I see that they make springs for the '03 Springfield up to 30# Ay help folks??:)
