Opinions needed: What happened to this P-38?

[Shadowsix]

I bought this all matching AC 43 Walther P-38 last summer rather inexpensively.

It functions beautifully, I've put 500 rounds through it with literally only a few feeding issues. So I'm happy with it but it came with this bend back of that band on the front of the slide.

I've not only wondered how that happened but should I get it repaired? I doesn't seem to cause any function issue but aesthetically it looks weird.

I would figure that if the thing had blown up before it would not only be non functional anymore but also a lot more damaged.

So did it just get knocked hard on that band of metal and bent back or what? The person I bought it from did not know (or wouldn't tell me).
