The pin O.D. was fine for the couple Colts I put this safety on. I did file/stone down a bit of the width of the paddle though. They were a little wider than I expected. Also, I had to remove a bit of material to clear the plunger tube.
Also - and most importantly, all safeties still need to be fit to the sear for proper function.
Sorry - no pics. And thanks - Yoda was a wise oid Jedi.
I tried and did not like the wide safety. even after shaping. Pin diameter was fine, as stated above needs fitting. Never attempt to drop-in 1911 parts, especially thumb safeties. Just my experiences.
I've used them and like a wide paddle for competition use, I lean toward the narrower ones for carry though. Fitting is generally required on safeties although I have never had a problem with the shaft.
