good info above, I've had LOTS of the older Speed,Service and Secuitry sixes, loved them ,carried them ,BUT they are NO longer "supported" or parts available, or serviced by the factory, sooooooo,go with current production, lots of good , current stuff out there,,,most of the "collectors" that I know have 'retired' their old models, especially if in the box ,as new, mint, safe queens ,whatever one likes to call them...the other guys, ( owners, users, have them shoot them) and will till they fall apart or quit................last few we had sent back to the factory for service, were NOT serviced, NO parts, and returned to the owners ,,,,,,,,,,,,,,,sorry discontinued is discontinued.......
