Yes, from buds own description "
They're being offered in two categories as far as condition; FAIR and P00R. FAIR indicates that the firearm is perfectly serviceable, but the finish may show a good deal of wear, and the grips may or may not be original. P00R is the same as FAIR, just with more wear evident."

yes they are functional guns the ruger police service six is a security six with a non adjustable frame notch type sight These are not show-pieces, they're working guns and show the holster-wear expected in a service sidearm, however they're perfectly functional.

During checkout you can also add buds lifetime warranty for $18.50 so even if you had issues you could get it fixed or replaced with no issues.

Andrew, yes Sir they are functional. A bit worn but functional. Cheers and stay safe!
