Although after market slide releases are available, it is not really needed.

The best way to release the slide after inserting a fresh mag, is to grip the slide with the left hand and pull it back and release it to chamber the new round.

One "issue" with some folks is that the cheap military surplus ammo is corrosive.

This means that corrosive salts are deposited in the barrel and must be washed out with water, before oiling the barrel.

This isn't as big of a problem as some might think.

Let's look at disassembly and cleaning.

The CZ-52 has take-down buttons on each side of the frame, much like a Glock.

To remove the slide, you must remove the magazine and make sure the pistol is empty.

Then, slightly pull back on the slide and pull the take-down buttons downward.

Then you let the slide move forward about a quarter inch...

And the slide will come off the frame.
