Can anyone here tell me what size punch I need to remove the rear sight on a Python. I need to mount a base for an optical sight. Also, do I push it from left to right, or, right to left as the gun is held in the shooting position. Thanks for any and all help.

Buy an .039 roll pin punch.
A roll pin punch will not ding up the pin.

Drive the sight pin out from left to right, as you'd sight down the barrel.
In this case, direction really doesn't matter, but that's usually the standard for sights and pins.

Unscrew the sight elevation screw completely until it disengages from the frame, then tap out the pin.

THE INSTANT you get the sight off, wrap some tape around the sight leaf to prevent the elevation screw retaining pin from falling out, and to prevent losing the two small coil springs.
If it falls out, the elevation screw along with two of the tiniest balls and spring you've never seen will fall out be gone.

Thanks for the info. Now off to the Bat Cave and see if I can get this done.

I looked everywhere. I need to punch out the rear sight piun on my Colt New Frontier 45 colt. Its a little bigger at maybe .045" or thereabout.It wont budge with the regular pin punch left to right or right to left.

Thankyou Dfariswheel. I tried looking at Brownells but couldnt seem to find it. Either way Im goingto send the gunin to Colt anyway to change out that Accro sight for the Elliason.It shoots 4" high at 20 yds with the rear sight all the way down.I heard the Elliason will give alittle more adjustments down and a better sight picture. Also just didnt like the accro rear blade inside that block.It gave a confusing sight picture for my eyes. Merry Christmas everyone!!

Be aware that when Colt installed a special order Ellison rear sight, they also installed a Colt Patridge front sight.
This is an undercut Target type sight.

If you don't want the Target front you need to tell them.
Also, make sure they return the old sights. Even if you don't want them, you can sell them for good money since Colt sights are almost impossible to find these days.
