too many times it was used I guess.
no idea if it's typical wear but if true it's a poor design decision as it leads to replacement of the slide instead of just the lever

Rather than poor design specifically perhaps the metal could be harder there or a sacrificial piece could be installed there (additional design could certainly solve the issue) with a small screw that could either be more durable or replaced easily. 🤙 1911 is a classic though.
