I'd just give it a thorough cleaning and re apply lube. I tend to run a little wet for break in.
I'd shoot it first using good name brand FMJ ammo. If there are issues then address them.
Some 40's do have a tendency to break followers. The feed ramp is sometimes just a bit long. Hopefully that's addressed and no longer an issue.
If it isn't then that's one thing to address with shortening the feed ramp and maybe some Lakeline follower although Kahr will replace the broken ones.
Basically don't fix what isn't broke. In the immortal words of our good friend Jocko, shoot it like you stole it.
