In order to save the time researching it myself, may I direct you to Kuhnhausen .45Auto Volume #2?
Looking at Page 162, Figure 153 of Kuhnhausen Vol. II - There's a dimensioned side view of the 1911 sear with tolerances, but it's hard to answer your question directly. The problem is that all dimensions are referenced from the center of the sear pin hole and the sear's shape is pretty complicated. Maybe a machinist could give a direct answer, but it's too much for me. One way you could compare the three sears is to stack them on a pin punch which is the same diameter as the sear pin. This will at least give you a better idea how they compare. The differences you see may be in areas that don't matter in terms of the standard shape and function.Originally posted by PKRCKR:
I am probably not asking this question righr but here goes: I have some factory sears (colt and SA) that were replaced by my gunsmith and while going through my container of parts that were replaced in the past. I placed three factory colt sears on top of each other(I keep the parts labled and seperated) and noticed that they were different lengths.
The question I have is: Is there a correct length for a sear and what is it:
