1911 hammer pin fitting

[golfwarrant]

When replacing the hammer pin on Les Baer 1911, I ran into an inersting problem. Replacement part is Cylinder and Slide. I could easily insert the pin halfway into the hammer from either side, but the pin would not go all the way through. My first thought was the possibility that the hole through the hammer was not drilled straight through in one pass, perhaps leaving each side of the strut channel slightly off from the other? I just can't see a parts maker not simply drilling straight through the whole piece in one pass though. I'm not a gunsmith, so after a short while trying to reduce the pin diameter by wrapping and spinning with metalwork sandpaper, which didn't work, I put the old pin back in before I got too enthusiastic. Any gunsmiths have experience with this sort of thing?

Did you measure the hammer pin? Not all replacement parts are perfect.

Regardless, the pin easily slips in halfway from either side with slight wiggle room. It's only after the head of the pin reaches the other side of the hammer strut channel that it binds. But I know it fits on that other side also from the outside. It fits both sides easily, and slides in easily until it binds entering the opposite side of the hammer strut channel from either direction.

C&S sells an over-size .157" pin for worn frame holes.

Surely your Les Baer doesn't need one yet!

But if you insist on using it, you will need to ream the holes to fit.

I didn't get the oversized ones.

Hammer pivot pin or hammer strut pin?

Sure the discrepancy is in the gun and not in the pin? When dealing with small shop/semi-custom makers, anything can be off.
