Sounds like a Firestar to me also. They came in 9mm, .40S&W and .45ACP. They came in blued or Starvel (nickel) finishes. All steel, SA only single stack guns. They come packed with features that you would expect to find on more expensive guns. They have beveled mag wells, full legth internal guide rails, front and back checkering, checkered rubber grips, checkered and squared trigger gaurd, dovetailed front and rear three dot sights, oversized and checkered controls, ambi safety, extrended tand to lessen hammer bite, beefy all steel ejector, swithable mag release and a belled bbl for better lockup. They are well designed guns that are now out of production.
I have a M-43 which is the 9mm version. It has been 100% with all ammo and I have shot 1.5" groups with it in Bullseye matches at 25 yards. It is one of my most accurate semi-autos even though it is very small. It is harder to shoot well because you have to concentrate but they have more accuracy then you would imagine. They are very heavy and being SA only, I don't like them for CCW but they are great guns. I got mine for about $250 and think it is one of the best buys I have made. You can find them for very low prices and they are worth picking up if you can deal with the extra weight of the all steel construction and SA trigger. I have retired mine in favor of a Kahr K-9. The Kahr is all steel also but is several ozs lighter and has a DAO trigger with no external safeties. It costs more than twice as much but I feel it too is worth every penny.
