My brother's pistol fires fine - its the accuracy which is the pits. It is the latter production, dull finished frame. Bottom right.

My uncle had one of the early production, glossy finished TP-22s - this one was a definite winner. Though a little bit finicky on what it ate, its preferred cartridge was very accurate at typical 'pocket pistol' ranges. Quarter sized groups at 20 feet were pretty much a given - what a sweet little gun it was. Unfortunately, stolen in a burglary of their home.

This website has IJ parts for your pistol - maybe they can be of further assistance.

Also saw this link - maybe the information will be of use to you.

Good luck. :t

 

The firing pin channel might have been dirty, and putting oil on top of it will only exacerbate the situation.
Also check the face of the slide, for a small piece of crud that's keeping the slide open that teensy little bit.
A third area to check for smooth ops/clean is the mainspring strut.

To be sure it's clean, w/o disassembly, give it a dunk 'n swirl for a few minutes in a pail of kerosene (at any Hess gas station).
Cock it, work the slide, and pull the trigger, several times while it's submerged - to work the kero into all the nooks/crannies.

When you wipe down the exterior, the interior will be left with a thin oily film from the kero, a plus.

Try it again - and if it still misfires, you're gonna have no choice but to tear it down.

 

I love seeing fellow Kerosene fans when it comes to gun cleaning. :Blasting_

 

Pete, I will try your advice. Thanks.

J.R., mine is like yours pictured on the right , but my slide is highly glossed dark blue and the grip frame is purplish.

 

It sounds like your is one of the early models then - congratulations on your good fortune. Thinking on it, another characteristic of my brothers was that the rear sight is intergral with the 'rib' on top of the slide, rather than adjustable which I seem to recall was with the older model.

I also recall that American Arms picked up the design, or something very similar to it - PX22 I think was the name. A search for a manual on this model may prove of some benefit. I found this link on disassembly of TP-22 of firing pin mechanism which might help.

Found it doing google search on American Arms PX22 - theres quite a lot of feedback.

:yeahthat: :beerchug:

BTW - Those little Walther look-alikes were, at various times, made and/or imported by, Erma (the original maker, IIRC), Iver Johnson, and American Arms. I sem to remember a fourth brand name, but can't recall it just now (does that make me a politician?).

 

Pete,

EXCAM RX-22, by ERMA, is the other variant that you are thinking of.

...and, automatic transmission fluid is a great cleaner & lubricant, too.

Yep, that picture above has a Erma Excam RX22 - its the one on the top left hand side. A bit bigger than the TP-22 - its a dead wringer for the orginalWalther PPK, to my eyes anyway.

 

j.r. guerra,

I am gonna guess that the "plastic" pistol is a Grendel. It appears to have no removeable magazine, and you load it through the ejection port, right?

Give that man a cee-garrr! :bthumb:

Yep - P11 .380acp, iirc. They later made a removeable magazined version, I think called the P12. Uses standard AR-15 strippers to load. Has a looooong trigger pull, firing almost when trigger hits the frame. Has something to do with super light hammer, needing high speed spring to work. Or something like that.

You can really see the Kel-Tec influence here - I call these Grendels Prehistoric Kel-Tecs . . . I wish I had broke down and purchased their folding .308 bolt rifles when I had the chance. Fluted barrel, Sako action - tres chic!

 

I tried disassembling the firing pin but could not figure it out, and found no info on the net.

Actually, there are instructions with photos on the net. I found them with Google after I bought my IJ TP-22 :

Thank You JackStinson - very helpful links included. :bthumb:

 

So the blind pin, spoken about in the link, needs to be removed from the left side of the frame, before the firing pin and firing pin plug can be removed, I guess? That's the best explanation and set of pictures I have seen so far. Thanks for the info. :bthumb:

 

Here's an update on the firing pin removal on an IJ TP-22. Forget the blind pin removal part as the blind pin that was circled in the picture has nothing to do with the firing pin. I used a large and small pair of hemostats for disassembly of the FP.
1. Remove the slide.
2. Push the rear of the firing pin forward as far as it will go with a small screwdriver and grab/clamp the front of the firing pin with the large hemostats, preventing it from retracting.
3. Remove the safety lever being careful not to lose the detent ball and spring.
4. Make sure the firing pin is fully forward and pull out the firing pin plug from the bottom of the slide, the cross-shaped thingy, with the small hemostats.
5. Allow the firing pin to retract with the firing pin plug removed and the FP and spring will come out the back. Be careful when releasing whatever is holding the firing pin forward as it will shoot out the back if you are not careful.

I am having light FP strikes and I replaced the FP spring with a lighter spring of the same length. My intent is to get slightly deeper strikes with the same FP and a weaker resistance return spring. I reassembled everything and will try it out tomorrow. I'll let you know.

 

I still have light strikes. Perhaps hammer speed or firing pin length issues?

 

Hello! I have been looking everywhere for instructions on how to take apart the firing pin and ejector from the TP 22 and I have to say your instructions were the most helpful thing in the world!

Now to the bad news 😂 I cannot for the life of me figure out how to put the detent ball and spring back in order. When I took hold of the firing pin to remove the safety lever, the detent ball and spring shot out. Luckily I caught and saved them. Unluckily, I didn't get a chance to see how they fit in. I am new to gun ownership and am in desperate need of help. Would you be able to give instructions on how to put all the pieces of the slide back together and possibly include pictures? Thank you for everything!

 

The Iver Johnson TP-22 is a rebranded version Erma RX-22. Numrich Arms has a schematic for the RX-22. Maybe the schematic will help you get the slide back together.

This was extremely helpful! Thank you so much! The slide is now back together and after a thorough cleaning I'm hoping it will cycle rounds! I'm going to try putting mini mags through it as so many have recommended

 

Glad you got it back together. A friend had a TP-22 and it was a really good little gun.
