Pistol primers with anomalies, are they safe?

[MrSpiffy]

I'm brand-new to reloading, as you already know if you read my .223 reloading thread.

I'm looking over a bunch of brass I saved from a while back, and I noticed that there are a bunch of rounds with markings on the primers. It's like they formed to fit the shape of the firing pin, or formed a crater.

Looking for flattened primer pictures, it doesn't appear that this is the case here. There's still plenty of radius on the bottom of the primer cup. It could just be a strong firing pin spring, or just how some guns fire. (The rectangular shapes seem unique to Glock pistols..?) But, I really can't say for sure.

Before I even put effort into these, are these cases safe to reload? Or are these markings indicative of some issue that hints I should avoid reloading these?

I would load them.

I would reload them. That is a sign of excessive pressure, however, in my experience is also a product of the firearm. I had a Beretta M9 I sold that would do that to just about any round, even .380 auto, due to a firing pin hole being much bigger that the firing pin. (thats not why I sold it). If a 223 did that, I would be nervous

Big hole around the firing pin. Pop the primers out, swaged them, & load.

They are all fine as far as pressure signs go, still very well rounded on the edges.

The top ones look like the weapon has a sloppy firing pin fit, the bottom are Glock FP marks.

Awesome! Thanks, everyone! I'll get them cleaned up for reloading.

All good brass. If you find some where the lettering is peened out the the point of being hard to read - the brass is soft, there was excess pressure, they are many times reloaded, or all the above. And I still load them, after careful inspection. This applies to 9mm (and the pistol I have to shoot them in). Other calibers - different criteria for what is acceptable.
