MCP35 rear sight

[ford8nr]

Trying to adjust my 'drift adjustable' rear sight on my Girsan MCP35.
WON'T MOVE
Tried my std way, padded vice, wood dowel/hammer - no luck.
Bought a sight pusher - no luck
Back in vice, brass punch/bigger hammer - no luck
Are they glued/locktited in ?

I'm sure someone here is smarter then me.

What is your vise padded with? Bolted to an immobile bench or pedestal? Try using aluminum/brass/copper/lead jaw liners to get maximum energy transfer from the hammer blow into the sight you're trying to drift.

Also If it is lock-tite'd into place, you can use a heat gun on low to warm up the slide and loosen that compound.

 

[ford8nr]

That was my thought
How does hear affect a creacoat finish?

 

[General Geoff]

Cerakote will tolerate way more heat than whatever adhesive or thread lock compound may be hidden under the sight. Keep it under 500F and you'll be just fine

 

[ford8nr]

Just getting frustrated

Use a steel drive pin punch.

ford8nr, I feel your pain. Just had one hell of a time changing out the sights on a BodyGuard; even went to a steel punch and a machinists hammer to move one of the OEM sights.
Gave it a good soaking with penetrating oil, and even that didn't help.
Finally, carefully, lined it in the RealAvid sight pusher, clamped the pusher in a vise, and really leaned on the pusher knob. It made an ugly noise, and the sight moved. Rinse/repeat, but it wasn't pretty.
The TruGlos are in, and they were worth the trouble, but jeeze.

Look at the inside of the slide under the sight to make sure there isn't a set screw before you do any of the above.

Got a reply from EAA, I had asked about Loctite

The rear sight is friction fit. Glue and/or Loctite is not used.

Gonna try freezing the site this weekend.

Heat & cold and liberal amounts of penetrating oil. Don’t lose patience.

The vice is key. It must grip the slide solidly, not allowing any movement. A big brass punch should be adequate if the vice is set up properly.

Hey, I'm a great fan of Miami Vise Sorry drband...
Your point is well taken. My long suffering ShopFox wears an equally long suffering set of leather jaws, purchased from a local shoemaker. It lets me get a really good grip on the work, without marking it.

Use a steel drive pin punch.

Hate to resort to that, but if the sights being removed don't matter, have at it.

And yes, be patient. It's one of those damned 5 minute jobs that can take all day.

Makes me wonder if the sight dovetail is tapered. Typically have to knock it out to the right, if that's the situation.

I believe all sight dovetails are tapered. Tapered tighter to the left. "In from the right; out from the left".

I swapped a set of sights on one of these. They're pretty tight.
