Today I get to go and meet the third gunsmith about this Little Pistol
Many gunsmiths don't want to work on such little .25's they may be biased against them. The assumption I guess is that anyone who has one is going to use it in a bar fight. But many people shoot and collect all kinds of guns they would never get into a gunfight with. Or it may be that he thinks you will not like the price.
JamesK, I know how striker fired pistol firing pins are made, most of the ones in .25 ACP's are simple little things anyone who knows anything about a metal lathe should be able to make, and to harden and temper the sear.
These are things I do all the time on my own guns, though I'd hate to try to make a living doing it. And this is probably the squeeze the gunsmith Nissan will face tomorrow, it will take a minimum of two hours to reproduce a striker if it needs a heat treated sear, and looking for a living shop rate the gunsmith is going to ask himself whether or not Nissan loves the gun enough to pay for it.
But the best way to replace it would be to do the tedious work of looking in GB every week until it is found, and, unless there are more than one just buy it. A striker for a baby Browning firing pin (Striker) costs $38 new.
Nissan, have you looked in Firsts red book? Page 124 item 6 "firing pin" It's a 1909 model but may be the same even if it's a different model.
605-343-9544 Jack First, and he may not have one.
If you aren't attached to it you can make a tidy sum selling the parts off, heh heh, though it would be a boring job, many do that.
