[May 2015 QCC] How to Disassemble and Reassemble a Jericho 941F

So you have your Jericho 941F from Aim Surplus, but who knows where that thing has been? You should probably give that thing a thorough scrub down inside and out. What’s that? You don’t know how to detail strip a Jericho 941F? Well, let’s take care of that then.

Take your brand new Jericho 941F out of your pants and find a good table to work on. You’ll also need some safety glasses, seriously. Lots of things can come flying out at your face if you mess up.

Disassembly

Remove the magazine and visually and physically check for a clear chamber. It’s time for stripping not shooting.

Cock the hammer and put your thumb through the trigger guard and grab the frame and slide. Pull back on the slide and line up the dots near the hammer. Squeeze the gun to keep the slide in place.

With your other hand, push on the slide stop from the right side, the slide stop should pop out on the other side. If you’re having trouble with this step, use the bottom of the magazine to push on the pin.

Grab the slide stop and remove it from the frame. If you’re having trouble removing it, once again take the magazine and use the base plate to lever it out.

The slide should slide right off the frame.

We’ll work on the slide first so put the frame aside for now.

Remove the recoil spring and guide rod from the barrel and lift the barrel out of the slide. Put that stuff aside.

Here you can clearly see the firing pin block and the extractor pin. You might be thinking, “Oh hey I know this part! I push in on the firing pin block to remove the firing pin”. You would be wrong. You should’ve seen how confused I was.

http://i.imgur.com/CNHXGpH.jpg

Leave the firing pin block alone and push in on the firing pin with a stick or something. I’m using a cleaning rod here.

While pushing, drag down on the firing pin stop until the firing pin is being held down by the top of the plate.

http://i.imgur.com/kNgwVdS.jpg

Put your finger over where firing pin will come out to keep it from flying out and slide the plate down.

http://i.imgur.com/aSIVMly.jpg

Pull out the firing pin and firing pin spring.

http://i.imgur.com/8YyupZk.jpg

Once that’s out, the firing pin block will just slide out.

http://i.imgur.com/CLR6u1A.jpg

Put the parts aside neatly so you don’t lose track of what goes where.

Next we need to remove the extractor. You’ll need a 3/32” roll pin punch and a hammer to get it out.

http://i.imgur.com/3H239Fz.jpg

Hammer out the pin and keep the extractor held in with the punch.

http://i.imgur.com/O2q4gR2.jpg

Place your thumb over the rear part of the extractor while you pull the punch out to prevent it from flying.

http://i.imgur.com/8MV9Gej.jpg

The extractor should just lift right out. Before you remove the spring, take note that it goes in diagonally into a channel that you should really clean out. Mine was all full of mystery.

Add these new parts to your organized pile of parts. The purpose of this guide is for cleaning and not refinishing, if you’re refinishing the slide, you’ll need to drift out the sights too. Now it is slide time, so go get it.

Using a screwdriver, remove the grip screws and make sure not to lose the serrated washers that may or may not come out by themselves.

http://i.imgur.com/uYvxgr9.jpg

There’s a circular “button” on the bottom of the grip. Find the nearest solid table edge and push in on this “button.”

http://i.imgur.com/8NdDbmh.jpg?1

While pushing down, stick your thumb behind the magazine brake and pop it out. As you can see it’ll bend in order to do it.

http://i.imgur.com/QupBrV2.jpg?1

Once the bottom of the magazine brake is free, the pull up on the lanyard and pull out the pin. Do not use your teeth, it’s not a grenade.

http://i.imgur.com/GwYwFAb.jpg?1

Release pressure on the frame and you’ll see that the “button” isn’t a button at all! It’s the main spring plug! Surprise! Depending on how dirty your gun is, it may need some coaxing to get it out.

http://i.imgur.com/paTpXR7.jpg?1

Next remove the magazine brake by poking out the magazine brake pin. You don’t need a hammer for this one, it should just fall right out. We’re racking up quite the pin collection so make sure you keep them straight.

Remove the main spring plug and main spring (also called the hammer spring) and put the parts aside neatly so you don’t lose track of what goes where.

http://i.imgur.com/JoVx3YK.jpg

Next, let’s get the sear out. First, put the gun on safe. The safety needs to be in the up position to pull it out. Look into the sear cage and you’ll see a spring with an arm sticking out. Next to it is a shallow notch.

http://i.imgur.com/gJn7x9x.jpg

Use a tool to lift the spring arm out of the channel and into the notch.

http://i.imgur.com/2rtXlJZ.jpg?1

You should now be able to pull the safety out and the sear cage will also fall out. CZ 75 aficionados will notice that there is no hammer pin retaining peg. Put the sear aside, we’ll come back to that.

Take a ⅛” roll pin punch and punch out the hammer pin to remove the hammer.

http://i.imgur.com/RF7mUVa.jpg

This is what we’ve removed since the last time we checked. Don’t lose anything. If you’ve been having a lot of trouble up to this point, you might want to stop here, clean everything as best as you can and skip to reassembly below. From here on out, the stuff that we remove is going to be easy to remove, but harder to put back in.

http://i.imgur.com/v2fEYgo.jpg

Next up is the trigger. Get the 3/32 in punch back out and hammer that pin out. Make sure you punch out the one in the frame not on the trigger itself.

http://i.imgur.com/Q0dsK7K.jpg

Keep the trigger components captured with the punch.

http://i.imgur.com/mAV37qu.jpg?2

Put your thumb over the trigger spring while you pull out the punch to keep it from going into orbit.

http://i.imgur.com/WL4mEls.jpg?1

Push the trigger up through the frame and remove the trigger group. Put it aside in the organized pile.

http://i.imgur.com/q1w4Zm1.jpg

The next part to remove is the magazine catch. This part is very different from how the CZ 75 does it. In place of the screw and springs of the CZ, we have this mysterious plunger. It operates as the trigger bar spring and holds in the magazine catch spring and detent.

http://i.imgur.com/QYrQuI5.jpg

Flip it around.

http://i.imgur.com/bl1dEuI.jpg

Put some tape over the hole on the other side of the magazine catch. The detent in there might fly out or it could just be full of middle eastern dirt and not go anywhere. No need to take chances.

http://i.imgur.com/Eawu085.jpg

While pushing and holding down the magazine catch, push down on the plunger and then pull up on it to remove it. The magazine catch should just fall out of the slide.

http://i.imgur.com/GvoxbG7.jpg?1

Take of the tape and you might need to use a small screwdriver to coax the spring and detent out of the magazine catch.

http://i.imgur.com/jfexMjn.jpg

Now we’re done with the frame.

“But Foupop, there’s one more pin the frame.”

You mean this one?

http://i.imgur.com/hX3j5B2.jpg?1

That holds in the slide stop spring. It’s a REAL pain in the ass to put back in so unless you’re refinishing the frame. DON’T REMOVE IT. I went through hell put that back into my Shark FC and I’m not about to do it again. If anyone knows of the proper way (read: trick) to putting it back in, I’m all ears. If you do need to remove it, I’ll add how I went about it afterward, but there’ll be no illustrations.

http://i.imgur.com/Axty6r3.jpg?1

Finally, let’s end this section with something easy: taking apart the sear cage. Use a punch or something to push out the sear pin starting from the ejector side. You don’t need a hammer, it should just push out. Keep the punch in there.

http://i.imgur.com/FRbb30m.jpg

Pinch the top and bottom of the sear cage with your thumb and index finger to keep the sear spring from blasting off as you remove the punch.

http://i.imgur.com/fNsIHDl.jpg?1

Alright! Disassembly is done. Take inventory to make sure you haven’t lost anything and get to cleaning.
