Matrix P228 won't fire.

[DV1911]

Completed a P228 from Matrix today. Very nice parts kit and frame. Decocker, trigger, and hammer works. It loads and ejects snap caps. But when I do the pencil/eraser test, it fells to shoot out the pencil. Please help me get this nice build to work.

Did you assemble the slide or Matrix?

Depress the firing pin safety and then the firing pin and see if it protrudes from the breech.

Matrix assembled it. Yes it does protrudes from the breech when I press down on the firing pin safety and firing pin.

Are you trying to shoot bullets or pencils? Go to the range, test fire, report back and if it doesn't fire, take pictures of the primers.

Could be your slide is riding too high and the firing pin safety is not getting pressed by the sear safety.

All slides are sent out pre-assembled. the double roll pin assembly is pressed into place with the firing pin depressed and then checked afterwards.

if you remove the double roll pin assembly, and press the firing pin safety up into the breech block the firing pin will eject out the back and you can check it for damage.

I'm pretty sure my slide isn't riding too high. I will disassemble the slide over the weekend when I have more time to play with it. Here's 2 pictures: 1 is with the trigger at rest and 1 with the trigger pulled back.

With the hammer decocked, trigger bar should be against the hammer pin, except when cocked or firing.

Check to see what part is holding back the trigger bar from returning to it's proper position.

Here's how it looks decocked.

Okay, it took me a while. As someone else stated, probably firing pin. When you disassemble the slide you will probably see what the problem is, spring is bent up or something. Let me know what parts you need and I will send it off.

the issue is he tried a pencil test. He has yet to try and actually fire it.

I need to find mags for my build. I can wait till I find a decent deal of good factory mags. or if someone would like to provide the dimensions to mod 92F mags i'd be inclined to make a few of those work

Another diagnostic thing you could try is to cock the hammer back and push on the firing pin with a pencil and at the same time slowly pull the trigger. At some point near the end of the trigger travel, you should feel the safety lever disengage the firing pin before the hammer falls, thus allowing the firing pin to move forward.

Also, after the safety lever disengages the firing pin and before the hammer falls, you can depress and release the firing pin with your pencil to check that the firing pin is moving freely and returning with its spring.

This should tell you a lot about how the firing pin is presently functioning, and if the safety lever is working properly.

Is the safety sear installed correctly. When you press the trigger with the slide off, you should see it pop up from the top of the frame to depress the firing pin safety in the slide.

I took apart a live round stuck it in the chamber and dropped the hammer on the primed case. primer went off. I'm good.

Be advised my pistol would not shoot a pencil out the barrel either.
