Kadet Mystery Continues

[1SOW]

 It's beginning to sound like there is an assortment of individual 'little issues' that can cascade into one big FTFire issue--OR vice versa---OR in-between.

The light strikes seem to be caused by poor mating between the breech face and the barrel,  leaving the bullet improperly seated,  which causes the first hammer strike to push the bullet into the chamber instead of igniting it.
Apparently this can be caused by several points of friction (rough slide rails,  extractor spring too strong,  rough surfaces on breech face and barrel,  rough mag lips and inner surfaces,  feed ramp,  etc...

Huh, never concerned a lot of those
Guess it's because I don't see many (if any) Fail to Fires with mine
But I can see where you're coming from

You're lucky Dan,  my Kadet would FTF at least two rounds per full (10 rounds) magazine,  best case scenario.
But I went to the range today and it worked flawlessly   shot  200 rounds (eley club, sellier&bellot standard and federal champion) without a single FTF.
I think polishing the mag really paid off.

That is interesting Luis
Could you please post a pic or two of where you are polishing the Magazine
I'd be interested in seeing that
Funny how, in the beginning, the Kadet Mag was its biggest short coming
Now it's the Barrel Pin, Firing Pin, FTFs etc

I took a couple of pics I'm posting now,  sorry for taking so long Den.
The idea was making it easier for the slide to strip the rounds (especially the top ones) from the magazine, polishing the areas contacting the rim seems to be especially important.

Thanks Luis
Man, I thought those Feed Lips were too sharp right out of the box
But now I'll bet they are a real Thumb Slicer

Thanks for the posts.

[Luis Paz]

good point,  but no Den. I broke the edges a bit when I polished the lips with fine (1000) grit sandpaper.
Also you don't have to press as hard as the bullets slide right in.

Well,

tinkered again (finally) with the Kadet again,   am getting a little better than 80% first strike ignitions with 13lb main spring and CGW race hammer, 100% with second strike in my PO6.  Am pretty satisfied with that, as I don't have to change main springs when changing the upper for carry or shooting fun w/ the .40s&w.

may try another small tweak,   will update again after trial.

respectfully,
kevin
