I have the Rock Island Officers model 45. I carry it on my belt in a Yaqui slide. Bought it because I missed my old Star PD. It’s a great pistol, 1 inch group (just one ragged hole) at 7 yards with 230 grain hardball.
I built this LW Commander in 1975 - the S/N is my initials and the year - and carried it for several years after I got my FL carry license.
Before that, I used it in pre-IPSC competition.
