P-64 not chambering

Hey guys been a while since I have been on. Here are a couple of pics of how far it is chambering. I fired about 200 rounds through it the other night and with about 20 rounds left it started not wanting to chamber it. So I figured it was dirty I cleaned it and it is still not chambering. Ideas, comments requests for more pics. This is my carry weapon so I need it to work flawlessly which it has up until now.

Try different ammunition.
Put in a stronger hammer spring.
Re-clean the chamber and the feed ramp.
Put the damn toilet seat down!

Might also check/clean/oil the breech face and make sure that nothing has obstructed the extractor claw. Might also check that the firing pin is fully retracting so that the rear of the cartridge isn't catching on a protruding firing pin.
While I don't think it's likely, this could cause issues similar to what you're seeing. A sticky/protruding firing pin could also cause "slam fires."

Already replaced hammer spring and recoil spring. took the dremel and a soft brush attachment to the feed ramp last night to shine it up. the Firing pin is not protruding had to check but it is not. tried 4 different types of ammo (glazer, wolf silverbear HP, wolf brown bear FMJ, and hornaday HP) all have same results occasionally one will chamber maybe 1 out of ten times. OH and that is the kids bathroom toilet seat stays up!

Tufrthnails,
Take your mag apart and thoroughly clean the inside, the follower, and stretch the spring out a little. I had that issue with mine and it usually eats whatever I feed it. That follower needs to respond immediately and move freely and, being that it's a blow back design, they get dirty really quickly. I now clean my mag every time I clean my weapon and the problem has not presented itself since. After cleaning, put a couple of drops of whatever oil you use on a cotton ball and use a small screwdriver and push it through. If that doesn't help check to see that the upper lips of your mag(s) aren't bent. Hope that helps.
Bill

If you jam the slide forward does it chamber (make sure you point in a safe direction)?
Does the slide move freely with the magazine removed?
I'd suspect you have some galling along the breach face and may need to do some light filing.

No it will not chamber without taking the mag out and pulling back slightly then it falls in the to chamber.

We see this periodically in the shop. Every time it has been a fouled magazine not allowing the follower to track true in the mag body. Previous response was absolutely correct. Take mag apart, clean thoroughly, and apply small amount of oil inside the body.

Could the feed ramp use a little more buffing? Maybe with Flitz?
And, just out of curiosity, what kind of ammo is that?

Your feed ramp looks messed up in the picture the angle of it is very important. Aside from that it seems your magazines may not be seating or feeding correctly. Perhaps the recoil spring is too heavy. Try propping the mag up (hold it up in place) when at the range see if its not seated properly when firing it. Take a solid look at your mag spring how it buckles and expands it might not be moving the bullets up and into position properly.

That feed ramp looks like it has a big crack in it, but it's difficult to tell from the pictures.

You have a P64 built in the year 1967. It might be a problem with the mags. The Poles changed the construction of the P64 around 1972 and made the feed lips on the magazines slightly longer which will cause feeding problems if you stick a "new" (post 1972) P64 mag into an "old" (pre 1972) P64. "Old" magazines will cause no problems in a "new" pistol.
Here is a picture i found on the internet for comparison.
