Default Front sight pin removal

Hello,

I want to know how easy is it to remove the front sight pin without removing any of the bluing on the pin or bbl base hole area?

Is it something a competent gunsmith can do with any problem or is each gun different?

The pin would be on a prewar target gun. I have not even ever laid eyes on a pin out of a gun more less see a blued replacement for sale.

I am also curious how much tension they are under. Can they be just pushed out with a cupped tool or do they need to be persuaded?

Thanks

We had always used a cupped punch of the correct diameter. Even so, some were very hard to move.

soak in Kroil, warm it up with a flame and yes...if you had to ask, it may not end well. Blueing loss due to a slipped punch is not what pre-war guns like.

Are there any blued NOS replacements if my gunsmith were to have problems?

Sounds like using a mallet on a punch might happen. Wish there was a tool that when you turned it would push the pin while the gun was in a vise.

The pin is only a press fit, not an interference fit.

Use:
A cupped tip punch slightly smaller diameter than the pin.
Penetrating fluid on both ends of the pin.
A piece of thin copper or alum shim with a hole in it the size of the pin and taped firmly to the barrel and sight base, for when the punch bounces off the pin.
Drive out from left to right. Install right to left.
If needed heat the area with a hair dryer until too hot to touch. It will not discolor the blue like an open flame.
