Hi all! First post here. I'm a new Jericho owner, full size steel frame in 9mm. I've been a fan for a couple of decades now and finally took the plunge. I have a question about compatibility between years of manufacture. I have to adjust my grip on the handle slightly to reach the slide release, and I know early Jerichos had an extended slide release similar, if not identical to, the Tanfoglio version on the EAA Fab 92. Google images for that gun if you don't know what I'm talking about. Anyway, since it's a slide release and pin, and the basic design has been pretty stable over the years, are these parts interchangeable between old and new production? If I could track down one of those slide releases I'd like to try it on my pistol just to see if it would allow me to reach the release without changing my grip.
Yours is a very good question; and I'm not going to pretend to know the exact answer. The Jericho 941 is based on CZ's basic pistol design. The IMI/Magnum Research pistols are not. The design characteristic of the IWI/MR guns are patterned after the original Desert Eagle. In other words the earlier IMI Desert Eagles pistols are not identical to the later imported IWI Jericho 941's.
(The original, 'R' models have the safety/decocker on the slide while the later, 'F' models have the safety and the decocker mounted on the left side of the frame. Your question appears to refer to the later, 'F' models which are, pretty much, CZ clones.)
I don't know if the two parts your interested in are interchangeable - maybe so, maybe not - but the importer/distributor would probably be the best party to call and ask. (Sometimes you can look at the schematics and compare the part numbers. Highly similar numbers often indicate interchangeability, OK.)
This being said, the IWI Owners Manual warns against making any Rube Goldberg modifications to the pistol. So what you really need to do is contact IWI Tech Support @ 717.695.2081, and ask them whether or not you can do something like this on you later, 'F' model pistol?
I'm going to add something else for your information: I'm certified to teach combat pistolcraft - NOT gun gamesmanship, but combat pistolcraft. We don't teach using the slide release; we treat this part strictly as a slide stop, instead.
On a larger pistol like the Jericho 941, the support hand is always placed over the top of the slide, pressed tight, and pulled backwards to release the slide in one smooth fast motion. The only time the slide stop MIGHT be used is if or when the support arm is unable to complete the required motion.
(An alternative method for releasing the slide is shown in the Owners Manual: It involves using the thumb of your support hand in order to release the, 'Slide Catch Lever'. If you use this method then it will NOT be necessary for you to shift your gun hand on the frame!)
In case you don't have one, here's an on-line copy of the Owners Manual for the Jericho 941
. It appears to be an exceedingly well written manual that is well-worth reading if for only it's gun-handling advice, alone!
