Edit: I see this is addressed three posts up.
My beef is when you’ve disengaged the safety, and the plunger snaps into place in that divot in the thumb safety, but then continuing to mash the thumb safety as to ride it for recoil control the thumb safety continues to travel further past that point into some squishy, mushy, yucky place in these recent Colts I’ve owned and handled. It might not affect the actual function of the pistol, but just feels awful.
I have fit thumb safeties from Wilson, Wilson Bulletproof (they are different), Ed Brown, and maybe some others I can’t recall, and they all had a very positive and definitive “bottom” which is usually right where the plunger snaps in place.
I just don’t understand Colt’s apparent inability to make this work. Even my dad’s early 1990’s Series 80 Government with its decidedly loose fitting has a better thumb safety “action” to it.
