It would be considered same-same Colt Series 70 inasmuch as it has no firing pin block. Note, though, that the real Series 70 both lacked a firing pin block and also had a collet barrel bushing. What we now call a "Series 70" would more correctly be called a "Pre-Series"Some say a “70” version 1911 shoots better than an ”80” series 1911 with the extra firing pin safety pieces. But no idea which the full size 5” 45 acp. RONIN is??
