Hello. It would help to know which particular Star handgun you're interested in.
I'll only comment on the ones I own or have owned. First, I believe the Stars to be good pistols. The older, more traditional single-action autos were prone to firing pin breakage if dry fired due to the way the pin's secured, but they offered a very good safety sytem in that engaging it lifted the hammer from the sear such that even if the sear broke the hammer could not fall until the thumb safety was disengaged. Some of the older Model Bs, Modello Supers, Model A, etc had trouble with anything but ball. Having said that, I bought one of the last runs of the Model B in 9mm. The Gov't Model length pistol's proven very reliable with a variety of ammo. They are slimmer than our 1911 and make for a very graceful piece. I still own and shoot it after having had adjustable sights added. I owned a M43 Starfire in 9mm that was reliable and accurate, but hit low for me. Still the gun appeared quite tough and never gave any breakage problems in several thousand rounds. I have no experience with the polymer or high-cap versions of this gun. I own a couple of Star M28s that work fine and are reasonably accurate, but not to the degree of Browning's HP or the CZ-75. I don't know how Stars would hold up in a torture test of firing thousands upon thousands of rounds, but mine have been fired quite a lot with no trouble.
You may not know that with the demise of Interarms as well as business arrangements in Spain, Stars are not currently imported here and that could cause parts problems. You can still find spare magazines, new and used, but
they will dry up in time. Best.
