CZ-21 Anyone ever see this?

Cleaning my CZ after a hunt. I noticed what looked like hair line stress cracks. The lines are on both sides of the housing in the same places. What to you think could have caused this? Ive never dropped or banged it in any way. I did buy it used.

Weird....not sure if the are stress related or just blemishes. I would keep an eye on them and watch to see if they grow or get deeper.

I have a used CZ-21 here. No cracks like yours on this one. How old is it?

New in 2010

Can you take a razor blade.....and gently test the depth of the (potential) cracks?

Note the almost identical type of line above the line in question in picture #4.

GENTLY!!!!!!..... lol
looks like surface lines from the mold to me.

should win a prize. A silver dime or something.....lol

Took some Acetone to anneal the cracks. Then used black epoxy to fill over. Never going to dive with it. Worst case i send it into Fisher. I think it will be fine. There are four cracks. All in the same places opposite of each other.

Most of those so called hair line stress marks are really just knead
lines that are developed during the molding process of the housings.

Good to hear.
