Hello. I do like the older Star pistols, but have to agree that parts are becoming harder to find each year. Dry-firing's out with any of the Star pistols pre-dating the Firestar series. This is because the notched firing pin's retained by a vertical pin in the slide that's covered by the rear sight. The firing pins will break, usually sooner rather than later, if you dry-fire very much at all.
The last new batch of Model B's that I'm aware of were offered as an overrun through Interarms before it and Star both folded.
This was in the mid-80s, I think.
You can usually get the gun to run with JHPs if you pick rounded ogive JHPs and I wouldn't shoot anything but standard pressure rounds in these pistols as they're a tad "soft." Mine works great with Federal 124 gr Nyclad HPs, Remington 115 gr JHPs, and Federal 115 gr JHPs, all standard pressure.
The B does come with a magazine disconnect, but it does not affect trigger pull as do the ones in the Browning Hi Powers. It is also extremely easy to remove should you so desire.
My experience with Model B pistols has been a bit more positive in terms of how they group, but they do not group as well as most higher-priced service type pistols. Expect no better than 3 and likely 4 in. groups at 25 yards. The sights may or may not be "on." I had one Model B that was dead bang "on," but the last one was way high at 25 yards.
Best.
