light strikes FTF- odyssey of a kadet

[painter]

One old man's perspective...

you're wasting a bunch of firing pin energy on the part of the rim that contains no priming material.

How to calculate a matching front sight       goto   https://stores.kensight.com/front-sight-height-guide/     
did it in the metric unit, mesuring

front sight hight  5 mm
sight radius        16 cm
impact distance  18 cm (with centered rear sight, complete amount of clicks is 51. So 25 clicks for centering the rear sights starting at one end position)
target distance   2500 cm

(16 multiplied 18) divided by 2500  = 0,1152 cm = 1,152 mm So my front sight should be 1,52 mm less than now 5 mm.
Desired size is 3,848 mm. Would be cutting the dot on the front sight in half. I stopped filing at 4,2 mm just scratching on the white dot.To have scope for design.

Now i can use my rear sight`s adjustability again to level in my holding area. Had to go up 3 clicks trying it with the scatt dry firing at home.

I like your perspective! I will work on the FP shape again !

Modified FP3 to avoid the rim a little bit more. Should work it away from the rim more again. Still 1 light strike in a box of 50 CCI sv. Ball pen FP spring and 17lb hammer spring. Remember your words:
You want the strike about .010-.015 inside the edge of the case,. Keep in mind that all ammo has variances, so be conservative.
Metric 0,25 - 0,30mm.


First row case, filing, testing on empty case
Second row shooting it
Third row, old style Kadet pistol FP dents, very probably the origina HS 18-20lb  - avoids the rim pretty much. Will try a FP4 copying that pattern - away from the rim but not filing the tip smaller, to have some coverage of the primer area. May be i should try a old style FP one day. If i can`t get rid of light strikes by filing.
Fourth row, light strike, ejected and loaded again -second fired.



Not only light strikes. It is even more interesting like that.
First box 1light strike, 2 missing rounds, one stove pipe . Ball pen FP spring and a only -4 coils shortened rec. spring.
Sec. box 1 light strike, 1 stove pipe.
Third box i changed to the minus 6 coils rec. spring. 50 shots no issues.
Fourth box 1 light strike, nothing else
Fifth box fine.
Sixth box one light strike.

Just one slide issue on 300 rounds. These modifikations worked. To ease the slide stop spring and to give way for the magazine follower when moving up on the last round. At least operated with the minus 6 windings recoil spring and 17lb hammer spring.

The filing of the front sight proofed as right on the range today.With one click up i could realise the desired sub 6 O’clock hold in the bright area. What helped me a lot to follow and cunduct my sights while pulling the trigger.

Checking when cleaning i found some more rubbing marks from the slide/ already shortened FP retaining plate.

Now FP3 and FP4 have the .010 inch (0,25 mm) distance from the rim.
FP4 is unshot. Want to keep the width for covering more priming area than on FP3. And try it out if it leads to alltime ignition. Was thinking of a new FP shape. Turned just a quarter to get more covering of the priming area away of the rim ?

Clockwise, FP3 first mod, FP now shaped, original FP4, FP4 mod

Rim split from impacts.

That FPins 3 and 4 i will test with 17lb and 18lb hammer spring.
Another experiment would be to use other manufactuers cheap ammo, like Aguilla and so on, with the 17lb and 16lb hs, ball pen spring and shortenend Kadet FP spring. To find the 99.99% reliable sv combi. Maybe because of different Primer sensitivities.
Still like to have the advantage of missfires for checking steady hold vs anticipation, for the enquiring eye surprised by just  a click. Like flinching or milking the grip when pulling the trigger. Or pulling the sights out of alignment just to the hammerfall.

Only 50 shots with FP4 yesterday in the Kadet. Still one lightstrike and one failure to feed right in the beginning.
17lb hs. Ball pen FPspring. Plastic spacer removed.

What are you using to lube, and how much?

[joerchi69]

Hello Painter,

after cleaning the firing pin channel and firing pin, the pin and spring gets a little bit of lube wich i instantly remove with a cloth or Q-tip. The rails i keep lubed but only with the thin lube. No grease.
On the Kadet i started with Gunnex by Ballistol. It is a middle thin oil modern variant. I tryed Brunox Turbo.Very thin lubricant and good for cleaning too. I switched to the Ballistol CunCer wich is also very thin and has ceramic additives.
Then the gunsmith Jan Bruder showed me the austrian Flunatec. A not oily not sticky ceramic lubricant wich is also adopted branded by Anschütz after testing. I degreased the gun and treated it with Fluna GunCoating. I use it as adviced for cleaning and lubing. As before the FP and its channel gets the same cleaning and "invisible" lubing. So no over lubing there. On the Shadow 1 the Kadet 2 slide has a lot of play in the rails, and is also not slowed down by over lubing. My Kadets mechanics are much more smoother and lighter operating than the ones of a club member.

Just wanted to check.

You don't lube the firing pin... right?

[joerchi69]

Right. I do lube for cleaning and do remove the lube before installing. Also in the FP channel.
 I´ve read of someone here who`s firing pin is not working properly if only one drop of lube is involved or creeps in from somewhere else of the pistol.

That might have been me. I was having light strikes well before the gun was due for cleaning.

I had over oiled the hammer pin and oil had migrated up to the retainer plate. It was enough to cause issues.

Thank you for the pointer painter -
i will have a look on this.
Could it be that superfluous lube on my Kadet from the rails is translatory motioned under the firing pin retaining plate ?
 And then gets pumped into the FP channel too ? Where it affects the movement of the FP. I will check it by shooting with dryed rails with excess Flunatec wiped of completely. And will check the FP area for adsorbed lube.

Only one light strike today on 350 CCI sv. The missfire was around 340. The dent on the manual ejected round was fine. Worked with the second hit. 17lb hs, shortened recoil spring length 92mm= 3.62inches, FP4, no spacer.
I started with a cleaned Kadet. Every liquid rest of Fluna lube i could find i wiped of. I sprayed lube rests out of the hammer area with a compressed air can. Wiped the rials down. With the Fluna the slide is still gliding lubricated even there is no residue of it.
I checked the FP4 and its retainer plate for materializing lube out of other spaces of the mechanics every box of 50 shots. Wiped the plate down two times. Did not clean other parts.

Good results.

Does the CCI SV leave a lot of wax on the feed ramp? I can't tell from the picture.
