I just bought an unfired 357 IMI Timberwolf. Very cool little rifle but it has not been made for 35 years and parts are scarce. It has been reported that the weak spot is the extractor which can become 'loose from wear'. Not sure if it is a non-cleaning/lubrication problem or design flaw. The one part I cannot find is a spare extractor so I want to make mine last. The fact that this is the only part not avail at Numrich etc sort of tells me someting!
As it is reported that wear is the issue then I am thinking of treating the extractor and the bolt where it operates in with some kind of hardening process, either a treatment like DLC or classic hardening. But I dont know anything about this other than it is not as straight forward as it appears, and esp with small parts. Any suggestions appreciated! ( pic is a stock image. I haven't removed mine yet to inspect)
