Yes, I like the idea of duplication or standardization.
In the late 80s, I had 11 1911s in varying degrees of customization, from the basic trigger job with beavertail, all the way to full race gun with compensator.
So yes, the 1911 was my favorite platform then, but revolvers had a place in my heart and safe. Two identical six inch 686-3s, a 6 inch 586, a 6 inch 17-3 as well as a pair of stainless (6" and 4.2") GP100s lived in my safe at some point in the last 10 years and most of these have been sold or traded away.
Lately, I have discovered the rugged P-series aluminum framed DA/SA Rugers so have a pair of Ruger P89s, a P90 and P91 (these all share the same platform), 4 x 1911s that are very closely set-up.
