22lr Revolver Failure to Fire

[h4344]

So I took a revolver I recently bought to the range. It was an inexpensive little 9 shot 22lr, High Standard 109. This was my first time shooting 22lr.

Using both CCI and Remington Golden Bullet ammunition I had an average of 1-2 failure to fire on each full cylinder with only 1 full cylinder going off without a hitch. Although I pulled out the misfired cartridges, rotated them and then they fired just fine.

The gunsmith at the shop said everything looked like it was in decent shape from the hammer to the cylinder. He did mention that it could be an issue with the headspace of the cylinder if the failures kept happening in the same slots (I did not have time to check).

Any thoughts on this one? Is there a way I can check the headspace theory without discharging the firearm?

Needs a new hammer spring. Quite common in the HS 109's.

That's what fixed mine.

Had similar issues? Cheap little spring that I just ordered so I am hoping it will solve the issue. Amazing fun when it does go off!

If you got it Cheap, that's probably why. If not, somebody saw you coming.

That one does not list the R-109 under the model. You sure thats the correct one? If its the one you used ill get it instead I just wanna be sure.

Good point. I just backed up on your part to the schematic. Then looked up the main hammer spring.
Not sure it's the right main hammer spring. But that is the spring you need.

A couple years ago when I ordered. Numrich had a totally different site.
You may need to give them a call?

Yea, it woulda been better to have paid triple for it, huh.

No hammer springs listed on Gun Parts Numrich that I can find. Trying google to see if anyone else might have em. Long shot but maybe one of the springs from the other similar models are the same?

 

[Certaindeaf]

I wonder if the Double Nine spring is the same?
Also, did you show the smith some empties or misfires? I wonder what the primer strikes look like.

Is this it?

I did not although I probably should have kept a couple. I was looking at the possibility of the other models having the same spring but there is no info I can see on dimensions for them.

Sure looks like it. It says it includes the main spring so I assume I would get the spring as well as the guide!

 

[Medic!]

If I remember correctly.
Part of the plastic saddle had also cracked on mine. And I bought an entire setup like this to replace it.

 

[jbett98]

Buy this, as the spring only isn't available.
