Sako/Tikka M90 Trigger Spring

So I always chased the lighter trigger, even with hunting rifles. For me, with a PRS or NRL Hunter gun, it is kind of a no-brainer to get a super light trigger. That's competition, not hunting. But I've started to see more and more reports of aftermarket, lighter, trigger springs (everything else OEM) causing slam fires once they are "used enough". IE they are lighter, and as they wear and get even lighter, rounds are shot if you slam the bolt home while in a hurry. Learning from the mistakes of others, rather than having to mess up by myself, I'm back to using OEM trigger springs on my Tikkas.
