Were the springs genuine Colt or reproduction?

 

First one was genuine Colt part. The next 2 were aftermarket. I cant seem to find another genuine Colt spring. Though at-this point, i’m not thinking another spring change is going to make any difference.
I may need to look into the other suggestions given here.
This gun was virtually new in the box, so I dont feel cleaning is the solution.
Thanks to all who posted replies. If I get it sorted out, I’ll let ya know.

 

How do the fired cases look when you fire it single-action? Are the firing pin hits deep and consistent?

 

Yes. Single action strikes are excellent

 

Firing pin could be damaged / blunted from someone dry firing it without snap caps.

Never dry fire a .22 without snap caps.

 

There is a way to put some more "oomph" in the V springs, but it sounds like the spring power isn't your problem. The problem likely lies elsewhere.

Such as the firing pin, or even the DA strut on the hammer, since this is occurring in DA & not in SA. I'm sure there could be other culprits too.

Would need somebody who knows what they're doing to take a look at it. Unless you have mechanical aptitude, then get the Jerry K. shop manual & examine it yourself.

 

I have a great amount of experience with S&W revolvers, and Rugers. Not very much with Colts.
I do feel comfortable getting the Jerry K. Manual and digging into it myself. At the very least, it will be an educational experience.

 

Also be sure to clean the living snot out of it before attempting any further diagnosis. .22 revolvers do all sorts of weird s*** when they get dirty.

 

When my single action colt 22s start getting mis fires, it means the chambers are getting dirty. The chamber fouling prevents the 22 cartridge from fully seating and thus cushions the blow to the rim from hammer/firing pin.

 

First step is to get an M16 military bore brush and clean the chambers.
The M16 bore brush is slightly large and a much stiffer bristle.
This is ideal for cleaning chambers but don't use it in the barrel, for that use a standard .22 bore brush.

Possible reasons for poor ignition....
Dirty chambers.
Short damaged, or altered firing pin.
Weak or poor quality aftermarket mainspring.
Excess cylinder head space.
Excessive cylinder end shake.
Short hammer drop caused by improper double action strut.
Dirty-fouled-old dried lubricant in the action.

 

A source of good mainsprings is Jack First.
They make factory equivalent Colt parts that are usually good to go.
Other sources are iffy and used Colt parts may be weak and often aren't real Colt parts.....

Colt double action revolvers seem to have to be fired in one continuous motion, almost like gripping the trigger.

My Official Police .22 will misfire with anything other than CCI Mini-Mags.

Most of the misfires I experience with my Colt's have been with reloads.

This is a good point. A Colt will feel different than a Smith and Ruger.

Even Miculek snapped an original Python when shooting it double action in his video.
