Whoops, yep I thought I was posting in a similar but different thread. But still your pistol has a minor issue with a loose front sight. That's why modern pistols are dovetailed, loctited and pinned in place. Staking is fine when done properly, but like anything it can be messed up. Dovetailed sights give you the chance to change types, heights and styles relatively easy and to most are worth the added expense. Now look at that plunger tube and make sure it's still tight.
