I could happily live the rest of my handgunnery life with my old Colt DE, my Single Six, and if permitted three also my rimfire STI. I freely and openly admit that my two G19.4 RS and dotted .22 slide is a higher performing, more practical combination, and I'm privileged to pour the rounds through them all. I also enjoy dalliances with exotic 1911s, one of which is my father's.
But put me on the line and make it all only one and I'll be keeping that Colt. I love the thought of a Briley-fit gun. I may have to discover an appropriate candidate.
