I have three Star BMs, a Star B, a Star Firestar M43 9mm, and a Star BKM (alloy frame Star BM).
Accuracy ranges form above average to match grade! Triggers range from good to great. Quality is excellent on all of them. Reliability on all but the 1945 era Star B and one model BM has been 100%. I had a few jams in one of my BMs, I think it is an extractor issue. The "B" was old and after getting a new mag, it ended up being very reliable, I am not sure if I had a jam with the new mag.
The downsides to the Star Bm is, the can bite your hand. They are heavy for a 9mm. The are Single action only. There are not alot of replacement parts for them, there are parts if your need them however. Some have extractor issues. I don't think they were designed for JHPs but most seem to feed them fine. I have been told that you should not feed them a stead diet of +P ammo due to softer then modern steels used in them. Firing pins can break in them if you dry fire. Most likely, your sights will be out of whack. Most of the ones I have seen have the rear sight drifted in the slot past center. When moved back to center, they seem to be on target. I don't know if they were just bumped or intentionally drifted.
They are not exact copies of the 1911 but they do give you the feel of a slim 1911. They are about 7/8th scale and seem to fit most people well. IMHO, they are the best deal on a used handgun right now. They sell for $129 at places like AIM and can be had for less than $200 almost everywhere. If someone is selling one for much more than $200, they are taking advantage of you. For the price, you can not beat them! They are now in the same price range as the Mak. There really is no comparison between the two. The Mak is awkward and clunky with terrible ergos and fires a weird 9x18 cal they costs more then 9mm yet is far less powerful. The 9mm is not a powerhouse but in the right load, it is a good defense round, the Mak is not much more than a .380acp.
