I tried often to shoot my S&W Model 52-2s in the centerfire matches but the scrores I shot with the accurized 45s were much better.
Al Dinan had his own machine shop in an out building and made a lot of the parts he used accurizing the pistols.He started from scratch making his own barrel bushings,barrel links and link pins.His long slides were works of art.
The Dinan pistols were the only ones I ever owned and was never aware of R.L.Shockey.
Clark,Behlert,Dinan and Swensen were the names associated with 45acp auto accurizing the most but that was 50 years ago for me so it's a bit foggy now.
