I was going through my gun list and I came across an email I received from Sig Sauer. I had asked a question about upgrading my grips and they said the newer grips should fit mine. They also said that they had made some changes/upgrades to the 220. They changed the mainspring, mainspring seat, hammer strut, and the hammer itself.
Now, my 220 fires fine and functions perfectly. The question is should I have the upgrades installed? I have always been in the mindset that if it isn't broke don't fix it. Would I notice any difference in the pistol after the changes were made?
As always: comments and/or advice is greatly appreciated.
