First, this is my first try at any kind of forum so if I am doing this wrong or at the wrong place forgive me.  I received a Jericho 941 9mm/ 40 from my father 25+ years ago-(how long he had it I do not know)- I just shoot it 3-4 times a year and sits next to my bed in a gun safe- I was told by IWI it is an "R" model or a baby eagle. It is all steel. 4.4' barrel, has IMI on grip, H-3 right above the grip, then KBI inc. on opposite side-  I need the slide catch lever for this pistol, it broke right at the pin- I have tried IWI, Gunspartscorp.com, gunbrokers, ebay, cfn parts, Gun Garage, HGW,& numerous gun part sites-  --  Does anyone know where I could purchase/ get this part  ???

I don't have access to a Jericho/941, but I'm fairly sure a Tanfoglio slide release will fit any steel BE/Jericho. Check with Cajun gun works, they would probably know.

Any pics of the broken part ?
The post above suggests Tanfoglio, better known as the EAA "Witness" is good information.
Just make sure you purchase parts for a small frame.

Are very similar designs with mostly subtle changes .
Try Numerich , but look under  "Kassner" as the mfr.
