Gunsmith installs rocking big dot sight.

[bones001]

To be safe, modify the part not the gun.

Of course.

To be clear. I didn't go to a gunsmith. I did this myself. I've installed sights on some of my other guns and done the fast trigger reset on my HK's. I know my limits but this didn't work out.

I should have been clearer, I was replying to the thread in general. I got that you did the sight installation yourself.

Reviving this thread due to similar experience. I replaced the factory sight on my 629-6 Mountain Gun recently with a fiber optic sight. I had to file the FO sight quite a bit to get it to fit. The dry fit looked great, I clamped it to the barrel and drilled. When I replaced the pin it was rocking slightly. There's a 0.005" space between the front of the sight and barrel. Would it be worth the trouble (or is it feasible) to file and redrill or just buy a new sight and do it over? Very helpful information here.
Thanks

If it were me, I would remove the front sight, drill a new hole in the front sight 3 or 4 times the existing hole diameter, drive a pin into the hole, face it smooth with the sides of the front sight, place it in the slot in the ramp, use a C clamp to hold it tight to the ramp, redrill the hole, install the pin and shoot until the cows come home.

don't allow him to drill larger and drift a bigger pin!!!

Why not? That is a decent alternative.

I fixed a similar front sight issue with a drop of black superglue. You can get it on eBay. I applied it heavy, then used acetone to clean up the sides. It's like it never even happened!

When I saw a "rocking front sight", I was expecting something extraordinary!
I've done a couple three of those myself, and mine don't move. But it's futzy work, and the chance of things going sideways is considerable. Particularly with the wire gauge drills involved, and the small drift for driving out the pin.
WHY Smith persists on this method of securing sights is a mystery. Changed sights, for individual preference, can be a huge improvement, and there's no reason Smith can't make it an easy, consumer serviceable job. Another of those "The right way, the wrong way, and the S&W way" things, I 'spect.
