The fault that does afflict the Firestars is that something wears on the hammer (IIRC) so you cannot flick the safety back on. You have to pull the hammer back just a touch to get the safety on.
I bought a M43 in Starvel, the nickel looking finish, as a carry gun. Small, plenty of weight to absorb recoil, what could go wrong? It shoots great at the range, but I cannot get it to point the same way twice drawing from a holster. Look for a weak recoil spring, too. Mine would fling the empties into the next zip code until I put a Wolff extra power replacement in there.With the heavy spring it handled +P defensive loads just great. Still, with the draw issue, mine is a safe queen these days.
