Greetings from a newbie! Am retired mailman. Have been buying. selling and trading firearms since 1979. I have a 70's Model 60 (no dash) and a 19-3, also have a 63 (no dash) maybe from the same era. In semi-auto I have a 915 with a later added 5906 upper and an M&P 45 2.0 Compact. Just acquired a beautiful 10-5 with C prefix (1966-67). Looking forward to future contact! Cheers!
