I am looking for a Sako P72 firing pin. Any ideas where I may locate one of these?

Odds of finding them are going to be slim to nil. But if it's just the tip that's busted off. (that's what usually happens) Send the gun to Tom, Duane or one of the other gun plumbers that post here. The old firing pin is drilled 3/8ths of an inch deep and a new tip is silver soldered in and cut and shaped to OAL. The gun will have to be test fired as some of these old Sakos had some wonky headspace. So you would have to send the whole gun. I would charge $150 CAD which is about $115 USD. I imagine they would be somewhere close to that plus shipping. I'm in Canada so I won't entertain cross border shipping.

Thanks for the response
