it's a FM, found it at the local shop in the used bin.it seems to be a older model as it does not have billboard on the slide like the ones iv'e seen lately.finish is greenish grey park.a little rough,but it's no browning,fits real good in my hand,and what a shooter.i mean to tell you its great. i got 3 -13 rounders 2-17 & 2 -30 round mags for $$300 they all feed & drop, good so i guess i did ok. now i need a good holster - does anyone know how to date a FM ?
