The Star BKM is an excellent pistol, in my opinion. About 10-12 years ago Century International Arms was importing these as surplus from the Spanish Guardia Civil (paramilitary police) at prices from about $120 to $150 depending on condition. I ended up with 4 of them, thinking they would be decent pieces to have on hand here and there without a lot of expense involved. Fired them all with standard pressure ammo, and all did very well (no malfunctions noted, point of impact at point of aim at 50 feet).
Then my sons showed up, and they needed another handgun. Then my grandsons started needing another handgun. All of a sudden I found myself without a single Star BKM.
Seriously, for a mid-sized 9mm pistol you could do a lot worse for a lot more money. Good solid pistols. Personally, I don't go in much for +P ammo and other nonsense, so I don't have any concerns in that regard.
About the size of a Colt Commander overall, but a bit slimmer in dimensions. All of the 1911 training works pretty well for the Star BKM (no grip safety, but I never really count on that anyway). Simply put, this pistol does what it was designed to do.
