www.brownells.comIt is a longer spring therefore a little tougher to get hammer started, but with universal hammer and a socket it is easier than the old original hammer.
If you are using the original hammer with the number #11 caps another thing I did was to open up (not deeper but widened) the cup cavity a bit with a 9/32 drill bit. I did this because the #11 caps were sticking inside the cup after firing and I would have to pick them out - now they fall out.
good luck - I will be giving the rifle a good work out this week-end to verify that spring is doing the job - I am real confident it will.
