issue with the safety on a baby eagle .40

[Mooseman]

A friend of mine brought me a .40 baby desert eagle. He had disassembled it and had not been able to reassemble it. I found the problem to be a stuck safety pin. With the safety set to fire I was able to pop it back in but it was stiff. I worked the safety on and off a few times and it restuck. After unsticking it again I was unable to make it jam again. My friend admits to hosing the gun down with wd40.

My question is does this need to go to a gunshop or will a thorough delubing and relubing with a proper gun oil solve the problem?

I seriously doubt WD-40 had anything to do with it, much.
I use it all the time for cleaning old grungy guns in the shop.

What I imagine happened is, WD-40 simply did what it does very well, got in there and dissolved some old dried oil & dirt or a metal chip in the spring plunger hole.

Which promptly moved trying to get out, and got wedged between the pin & the hole.

I'd take it back off, clean the hole throughly with a pipe cleaner & solvent, then re-lube & put it back together.

If it works then, that was all it was.
