In this video I compare and contrast Colt 1911s, 1911A1, Series 70, 80 & 90 pistols.

I do my best in this tutorial video to share what I know. ----- Ways to follow me and contact me - YouTube - The Texas Gun Vault: @thetexasgunvault The Texas Gun Vault 2: @thetexasgunvault2 Rumble - Texas Gun Vault: Texas Gun Vault 2: Facebook - Texas Gun Vault: Texas Gun Princess: Instagram - Texas Gun Vault: Texas Gun Princess: Email - texasgunvault@ Patreon- Mailing Address - Texas Gun Vault P.O.
