I took a chance and ordered three Pro Mag mags for my Star 31P. I ordered them from Tom Forrest Inc. (www.gunmags.com). They came today. I inserted the first one into the gun with some effort and removed it with some difficulty. It didn't seem to fit very well. I inserted the second one and had to slap the bottom very strongly to get it in. When I tried to remove it, I found that it was thoroughly stuck about a quarter of an inch below the gun butt, i. e., the mag release button wasn't the problem. I did everything I could think of to pry this thing out. In the process the base of the mag began to bend. Before I could get it out I had to (1) remove the base plate of the mag and the inner parts, (2) remove the slide from the pistol, and (3) hit the mag body from the top. At last it came loose and was removed. I didn't see any need to try the third mag. Of course I am sending these pieces of crap back to Forrest. There were a number of physical irregularities and defects in the mags evident to the eye. These are the only mags I have ever bought that not only wouldn't work--they can't even be inserted into and removed from the pistol!
