A few yrs back I bought a blue 58 on gunbroker . The ad said " bank vault tight lockup " . When I got , the lock up was sooo loose that I refused to shoot it . Didn't have much luck with the seller either then, so I sent it back to the factory . For $189+shipping , it was fixed . I have shot it quite a bit and will never sell it . I have a buddy that sent one to Bowen Hamilton several years ago and had it converted to 45 LC . Real sweet shooting gun . But I will keep mine in 41 magnum .
