Interesting question…….Do you know if SA has plans to bring back a .45 1911 4.25” with a rail. I have the full size Operator with rail and a weapon light and would like to do the same to a smaller 1911. I don’t have any interest in changing caliber, as I already stock too much ammunition.
Because the 5” is the full-size; a 4.25/4” is a “Commander”…Interesting question…….
I try not to answer a question with a question(s) and honestly I don’t know the answer on what SA is producing but why don’t you consider a 4.25 inch barreled 1911 a full size gun?
Also what is the barrel length of your Operator?
I owned “at one point” a 4.25 inch barreled 1911 Emissary 45ACP and it was a full sized gun.
