i have no idea. My husband passed away a few months ago, he had just bought this, probebly a smaller pistol but am not sure . I know nothing, lol. am trying to download a pic
it says Uncle Mikes size 1.......made in vietnam.....thats all i can find.I tried putting my rugar in it , it will go in, but too long for it. the rugar is a pretty hefty sized pistol. sorry i cant be of more help. I just shoot em , i don't study em.
Actually, that does help. I looked it up and an Uncle Mikes Size 1 holster is designed to fit "3 - 4" barrel medium autos" - http://www.unclemikes.com/fitcharts/sidekick_ambidextrous.html
