I've been using a Yaqui Slide by Milt Sparks, for many years, with my Colt's Lightweight Commander, and Colt's Govt Model. Works fine.
The only caveat is that if one is up and down quite often at work, etc., sitting in a chair with arms, it is possible for the arm of the chair to dislodge the pistol if one isn't careful.
I have a picture of me standing next to Jeff Cooper, at Gunsite, in 1981. Cooper's Colt's Govt. Model can easily be seen residing in his Yaqui Slide, made by Milt Sparks. He had it on the entire week I was there.
Answering the triva question, Jeff Cooper and Milt Sparks designed the Yaqui Slide for Cooper's use.
FWIW.
