Dating a star pistol
The Star Model BM has a magazine well that is beveled from the factory and its 8-shot magazines have a rounded follower.Note the flat at the forward end of the follower that engages the slide release lever.The thumb safety and slide release lever on the 1911 are both under spring tension via the plunger retained by the external plunger tube. There is a spring-loaded plunger within the slide stop lever itself and another beneath the thumb safety.
It has merged with another Spanish arms maker and it is important to note that new parts are being produced.Surprisingly, these sights are not at all "slow" to be picked up at speed. There are definite similarities to the 1911 visible in the external features of the gun and with the removable bushing as well as the swinging link, but there are also considerable differences between the two designs.The link is in the proper position for reassembly on the Star but would not be on a true 1911.This is problematical when wanting to remove the pin for cleaning.Disassembly is more like the Browning Hi Power than the 1911.
