It's ALL in the angle. Interestingly the exact angle is really unimportant as long as you can maintain that angle for every stroke. Almost any angle will give you an edge if you can bring the two sides together until a burr starts to form. Low angles work well for kitchen knive and steeper...
After trying many different carry guns I settled on the .44 Spl. in a DA snub years ago and in over 30 years I have not found ANTHING better for CCW use. If you can get one good hit with a heavy hard cast .44 Spl. - all the others run away.........

They fall out very commonly - especialy on Colt guns. It's just sloppy tolerance numbers. It doesn't harm anything - when the gun is assembled that pin cannot go anywhere. Just don't lose it - or go ahead and stake it in. It is not a "defect" - it's mass production.....

The good thing about tearing it down regularly is you can inspect parts for uneven wear or fitting problems before they do any real damage. Lube. Shoot. Repeat.
