Bersa/EAG Firestorm - Pitting and Rust on Slide

[American Muslim Gun Owner]

Hello Everyone,

Last year I bought a Bersa Firestorm and shot it at the range twice.

I recently noticed that the left side of the slide has pitting and rust on it. Any ideas what might've caused it?

Thanks in advance!

I've heard that the foam inside the case could retain moisture which could cause rusting. Not sure if your storing your firearms like that but something to consider.

poor prep work and possible storage combination.

Did ya carry it at all? I have some similar on my Bersa but I carried it a lot, in a hot sweaty environment for several years. Couple times the holster sweated through. I kept er oiled up pretty good but very similar looking rusting.

Ditch the foam case, or slather the gun in oil and place a barrier between gun and foam, like parchment paper or plastic. Foam doesn’t wick moisture out it just hangs around wherever it lands.

To clean it is I say some bronze wool and hoppes

The finish on these slides is generally pretty poor. I had one rust up on me after a day carrying and sweating through my holster.
Looks like the area that's messed up is by your slide release, so it might be oil from your skin. Best advice is to clean immediate after shooting and put it away with a fine layer of oil on it.

Do not store guns in foam cases

I have two of them and both are fine - no rust. I don't store guns in foam cases but in a socket lightly oiled. It looks like a storage issue.

Thank you everyone for the helpful replies. It looks like mixed results between all of us.


So, I've never carried the gun (couldn't even if I wanted to). Just two trips to the range. I noticed the same thing about the area where it is affected: I thought maybe I had something on my hand that rubbed onto the slide.


In regards to storage, for a few days I kept the gun in a GPS Handgunner range backpack with the very thick foam inserts. I'll give it a cleaning like you guys recommended and switch over to storing it in one of those synthetic socks with a light coat of oil.


Thanks again everyone. I really appreciate all the help!
