I Should Add
If you are looking at a used 1911 & there is just a single hair line crack in the frame rail right above the slide stop cut~out then buy that pistol if the price is right.
That is a crack that in no way affects the structural integrity of the frame or pistol & (in fact) some Colt & clone frames have that area milled out so that there is an open space between the front & rear rail section.
GOOD HELPFUL THREAD Bruce. :smile:
