buying a used ruger mkIv 22/45. Seller is asking $500 but comes with several magazines, a holosun red dot.

Not sure what to look for as this will also be my first used gun purchase.

how does it look? it’s a bit dirty

There is a rattle that speeds up when giving throttle. The sound usually goes away after the bike warms up. I dont ride often so this bike will sit for weeks before I take it out for a ride.

Its a 2019 R3.

How would I diagnose what is causing the sound?
