Improving The Kadet

[75Plus]

Joe, I've shot .22 pistol for quite some time, and NOT DRY FIRING is a standard rule.  Many name brands will peen when not inserting a case or a snap-cap before dry-firing.  I used spent cases with dowell inserts for bullets back in the day with my High Standard..
If shooters know beforehand, why the concern  IF it will improve the strike with a lighter spring?
"Warning,  Dry-Fire without Snap-Caps Can Cause Damage to Your Pistol".

Don, I think dry firing has been a problem about as long as there has been firearms. Not sure about match locks or wheel locks but flint locks would be harmed by chewing up the frizzen and wearing out the flint. Then along came the percussion cap and dry firing them mushroomed the nipple so a cap would no longer fit. Next came the rim fires that would peen the chamber face. (Not sure about pin fires)

Yep, I agree with your warning 100% (Warning,  Dry-Fire without Snap-Caps Can Cause Damage to Your Pistol") but "An ounce of prevention is worth a pound of cure"

I fully agree that having your cake and can eat it too is best, but the "biggy" is getting a conversion that's NOT ammo picky---like my HS or the model 41s- or....... 
I suspect you'll find a way to make it run.

For those who may be contemplating trying their hand at making an extended firing pin I made this sketch.



I made a tool to measure the distance from the chamber face to the shoulder in the pin cavity that stops the forward motion. The 2.038" noted in the sketch is the absolute max allowable.

The factory FP measures 2.022" so an extension of .015" is possible. Some have mentioned shortening the length of the max diameter portion to allow more FP travel. Just be aware that more than .015" removed from the tip side will get close to the peening region. Removing material from the hammer side will allow the hammer to contact the FP earlier and push it further but the tip starts further from the primer so that may be a wash. I have been trying different tip profiles with some success but no "Break Thru's."  Still looking.

Thanks :-) I may just give it a shot. Thanks for doin all the research!

I will shoot my 75Plus-modified Kadet early Sunday morning.  Got the slide back today, just as planned.  Will try the light hammer springs again, 13/15/17 lb, with the solid pin and the corrected barrel hole per 75Plus' original post here in this thread.  Can't wait.

This is fun.

Has this thread moved?  I am intested in the Kadet Accuracy. 

75Plus I sent you a PM.

Hi.. Dying to know the conclusion. My 75B Omega Convertible is light striking on 3 out of 10 shots consistently. The Pin is clearly not denting the rim deeply. My Ruger SR22 leaves quite an indention...Thanks!

I recently purchased a used CZ75 Kadet, and it has the problem of light strikes; 4-5 out of 10.  First I found a shattered roll pin that holds the barrel in place; replaced with pressed in solid pin.  Then I noticed that the barrel had shifted forward from the block/housing; the block that is pinned to the slide. The breach end of the barrel where the cartridge rim rest when struck was about .002" forward.  How can that be prevented?  I removed the barrel from the slide, and used a hard plastic mallet to lightly tap it back in place; so the end of the barrel if flush with the housing block.  I went to the range today; had only about 10-20% FTF (Rem bulk).  Most fired on the second firing; 2 would not fire at all after 3 or 4 tries.  It still has the old style firing pin with the rounded point.  What about cutting off a couple of coils of the firing pin spring?

Put a 17# hammer spring in your pistol and try it again.

If anyone is still concerned about the Kadet accuracy potential, I offer this target up for proof that the Kadet is limited only by ammunition. 
I have maybe 7 clean targets but this is the only 10x, and it was in practice last year.  I only had 40,000+ rounds through it at that time. 



This is 25 yards standing single hand two strings of five shots in 20 seconds.

Has anyone identified a competent gunsmith to perform this work?

I would like to get in touch with 75plus but I don’t have enough posts yet (I don’t want to post nonsense just to get numbers up).

If anyone could message me his contact information, I would appreciate it.

Thanks
