Help Jericho front sights moving

[fridge450]

any Jericho/baby eagle owners ever have a problem with the front sight moving. I recently bought a leather holster for my steel frame Jericho and it keeps pulling the front sight to the left this really starting to tick me off as it was very accurate before. also when I tap it back it seems there is gun oil under the site. I am still pretty new to pistols so any advice would be great thank you

Strange problem, I would set it and put a little bit of blue loctite on either side of the sight.
