IVER JOHNSON 22 PISTOL PROBLEM

[25th Tropic Lightning]

Looking for some Iver Johnson 22 cal pistol help.
When I pull the trigger, hammer falls, and when trigger is released it comes back only 3/4. When I help it, it goes to normal return.
2nd
Break open the revolver, pull hammer back, pull the trigger, hammer falls, release trigger, it comes back to normal position.
Why is the trigger locking up, when cylinder is locked into place?
Hope I made this clear! Lol
Thanks for your help!
Terry

Before parts replacement.....have you cleaned it thoroughly and relubricated?

 

[25th Tropic Lightning]

Yes, I opened her up, brake cleaned, then sprayed down with Ballistol.
I thought the same thing. I believe it's a 1915 pistol..
Thanks for ur reply!

Such is the nature of enjoying (repairing) old guns! The most economical way to go about it is to acquire many broken examples of each type so you can buy multiple replacement parts and spares at once to save on shipping costs.

Actually, the real game changer is getting set up to make your own springs and other small parts yourself. Eventually the supply of parts scavenged from other guns will dwindle and only those who can really DIY will be able to do more than display these guns behind glass.

This is very true! I've purchased a few IJ parts lots on Ebay.
Wouldn't you know I didn't have anything for this Supershot.
Very good tip! Thanks!

My guess is the hand is dragging on the cylinder as it returns to the resting position, and I'd try replacing the trigger return spring if a clean & lube doesn't fix it.

 

[25th Tropic Lightning]

Thanks for ur reply.
Well, I've put in the new springs, and now it's worse! Lol. GO FIGURE!!
Before with the Cylinder up, the trigger would return to normal.
NOW, the trigger doesn't return either way. I have to help it, every time.
This little guy was a bugger, to put back together. I just wanted a fun little pistol to teach the grandkids. What a bummer!

The placement of the trigger return spring can be a pain to get right on these. Did the new parts replace obviously damaged old parts or were they missing in your gun? Did the new parts look like the ones they replaced or were there significant differences?

It sounds to me like you don’t quite have the trigger return spring engaging the trigger in the right spot. If the spring is there and pushing on the trigger where it should be it’s pretty difficult to keep the trigger from returning fully.

 

[25th Tropic Lightning]

I just replaced the trigger spring, and the hammer spring. The cylinder arm spring I ordered was the wrong one.
They all looked good. Trigger spring had more arch than original spring.
And yes, I now understand what ur saying about the trigger spring placement, being a problem, and holding the trigger back. I shoved the spring all the way in to touch the trigger. I'll go back in there, and push the spring back. Is there any reason to snip off the tips of the spring, if to long?
Thanks so much for ur help!

 

[entropy]

You might have to; don't snip it too short!

One other tricky issue with MY IJ, which is much older than yours, is the hand spring. One end bears against the hammer (easy to see) and the other slips into a tiny hole in the underside of the hand, and becomes visible in the little window.

I don’t think the firing pin should be protruding from the frame like the open photo shows. Does the gun have a transfer bar? If so something is binding the transfer bar.

 

[Col. Harrumph]

Iver Johnson invented the transfer bar but not all of his revolvers have one. The others require pulling the hammer back slightly to a first click, so the firing pin clears the indented primer.

 

[Comp_jas]

Interesting, I haven't seen one with that vintage cylinder indexing scheme that didn't have the transfer bar.

I have two supershots (1932,1937) a .32 (1920) from that era. This one looks to be pre-supershot so maybe no transfer bar....but if there is a transfer bar something is wrong.

 

[25th Tropic Lightning]

Yes, there is a transfer bar in this one.
And yes it's acting up. I pull the hammer back transfer bar comes up, it's real far from the firing pin. Then I release the trigger. Hammer goes down, but trigger stays in the pulled back mode. I slightly push the hammer over to left side, trigger releases half way. I still have to help it go forward.
I very taken it apart 3 more times.
I've basically given up. It's beyond me!

 

[25th Tropic Lightning]

Trigger spring fits correctly onto the trigger guard slot. The 2 fingers are sitting on top of the trigger. Basically the way I see it, I can't move it forward or backwards, as it sits in the trigger guard slot that holds it in place.

 

[25th Tropic Lightning]

Sorry I haven't replied back, I don't get notifications when you guys respond.
I tried to set that up, but failed there also!! Lol. I just turned 62! Wasn't expecting it to get this bad yet!! Lol

 

[Comp_jas]

I had to fix the 1932 Supershot in the same area. I bought it disassembled from an estate sale. The transfer bar musthave been a replacement and was too long. When the hammer closed..the face of the hammer was hitting the top of the transfer bar. I ground about an 1/8 inch off the transfer bar.

When things are working...The firing pin should be flush to the frame...when the hammer drops the transfer bar fits into the cavity just below the hammer face. After the hammer drops.. if you continue to hold the trigger and slowly release it you'll see the firing pin retract which means the transfer bar is moving down.. if you gently pull the trigger the firing pin will protrude...on all 3 of mine I can make the transfer bar rise and fall with no binding.
