I sent my Lanber to a gunsmith as it opened up when I shot it. No spare locking plate available anywhere. It would have cost twice what the gun was worth to have a new locking plate made by hand, so I told him to keep it, he can use the barrels for sleeving. I'd buy a used Citori or a 101 before I'd buy a new Lanber. If you can't get parts you are screwed.
A used Beretta would be the best bet, but they cost more.
