I've seen a few people talking about problems with bent strikers/firing pins on their Tikkas or posting on the buy/sell/trade forums looking for a replacement. I recently had the same issue on my new Tikka and figured I'd share a way to get it fixed/replaced at little to no cost.
You can tell if your striker is bent from either the rear tang on the striker with the cocked indicator being at a noticeable angle instead of being parallel to the main striker shaft, and/or the bolt being significantly stiffer to cock/unlock when cycling. This friction also slows down the striker so constant light primer strikes are a telltale sign as well.
If your gun has this issue and its within warranty you can call the US distributor for Tikka, Baretta, and ask for the technical support line, provided the guns serial is in warranty they will either send you the replacement striker assembly in the mail for free, which is a quick drop in parts swap, or you can send your whole gun in for them to do it. If the striker bent at all from you removing it from the bolt that probably means the heat treat was bad as the metal should be strong enough to not bend under simple hand pressure, so it's not your fault and should still be covered under warranty.
You can also bend the tang back in to place by putting it in a vice and compressing it until they all align, but as previously mention the heat treat on the part is bad if you're able to do it so easily. That combined with it being bent and then bent back into shape means its already damaged and could break from use. I did this with my old striker assembly and it works well enough to be kept around as a spare for use in a pinch but I don't trust it to hold up.
Baretta had my new part to me in about 3 days and it fixed all the issues. They can also be bought from Brownells for about $120.
