Colt New Service versus Colt Officers Model
I recently purchased a 1937 Colt Officers 38 Heavy Barrel (Target). I adore it. So I am thinking I want to get another old Colt.
I found a heavily customized (SA/Bull Barrel/...) 1919 Colt New Service in 45 ACP that looks like fun for target/bullseye shooting.
I am just not clear on the difference between these original two models, but presume the Officers is based on the New Service. Can anyone help me understand the connection and differences between these two models?
