And I am close enough to walk.
I bought another Dawson precision front sight for my Model 69. I did The job once before, But I wanted an even taller front sight. Last time It took me day's to get the pin out. This Time I soaked it over night in PB blaster. Got my Armorers block out. grabbed the right pin punch , and have been tapping away for half and hour. Can't get the pin to budge. It ain't rocket science. It can't be that hard. Got it soaking again. Going to see if I can find a Frankford starter pin punch set somewhere. Cabela's has it on the web sight, But really want to get this done today if I can. Drilling the hole is easy. And I used blue Loctite last time. But I know Guy's do this all the time. You put the punch on the end of the pin, and tap 500 taps latter, it has not moved one bit.

You need some heat. Do you have a soldering iron? If so, put the pointy tip on it and hold it on one end of the roll pin and hold it there. Watch for the faintest, fleeting wisp of smoke and then try driving the pin out, but remember - it's HOT.
Notes: I usually miss the wisp of smoke and just hold it there a while - never on a roll pin, but on screws. I FREQUENTLY forget the part about it being HOT, even though I was the one who just heated it up.

No drill press, No soldering Iron either , but my room mate might have one.
I got a little movement out of it, maybe a 16th. I put t back in to soak in PB Blaster, I think tomorrow I will tap it some more and maybe buy a soldering iron. Heat, is a good option. Ever work workshop Wednesday on you tube, The seldom mess with lubricants , go right to the torch..

I put a soldering gun on each end of the pin Got it pretty good and hot. Still will not budge...tj I'm assuming this is a roll pins and that you are using a roll-pin punch. It sounds like it's gotten buggered in the process of going in/coming out.
With as much trouble as you are having with a roll-pin, I'm inclined to agree with 500fksjr, because there's something up if it's that difficult. It COULD be that the hole is not aligned from one side of the slot to the other, which would put a kink in the pin. Pounding on it will cause one side to swell up and make things worse. There can be SOME misalignment between those two holes and the hole in the sight, but if there's too much, there's trouble. I HAVE had this happen with a sigh blade hole misaligned enough to do that. Since I was replacing the blade with one with no hole, I was able to correct it.
Drilling the new sight half-way from each side will/can help.
This setup helps keep things lined up, even if the holes on each side of the slot are slightly misaligned, and I have no idea how the can get misaligned, but I've had some that were. This trick came from the Dixie Gun Works catalog for aligning the rear tang screw hole with the trigger plate hole on a muzzle-loader. Mount a center-punch in a vise. Make sure the punch is 90 degrees from the makeshift base. Line the drill up with the point on the center-punch and clamp the center punch base down. Set the off-side hole on the point of the center-punch and align the other hole with the drill. I would personally not try to drill out the old pin this way, because you are hand-holding the gun while drilling the half-holes to meet each other in the middle.

Try tapping the pin from the other side after applying some heat. I had an issue with an old rifle that the pin was tapered so it only goes one-way. You can pound on the wrong side for ever and it won't move, tap the correct side and it will come right out. Not sue if yours is tapered or not but it will not hurt one bit trying the other direction.

Pins comes out faster when you soaks 'em with blaster, PB Blaster.

Been soaking it in PB blaster For 4 days now.
I pull it out, Put the gun in my padded vice, Tap a couple hundred times, Put a soldering gun on each end of the pin till it gets hot, Tap another couple hundred. Pin has moved about 1/8th of an inch.
I think I might try putting the gun in the freezer, Then putting the Soldering irons on the pin's...tj

The statement was brought up in an earlier post, about using a Roll Pin Punch. I didn't see your answer. You need a true roll pin punch, not just any punch. Also heating a pin up, and trying to punch it out at the same time, may not be helping you out. Heat expands metal.
