cz 75 shadow loose back sight

[robchar]

Just picked up a cz shadow and it shoots well etc but I had the back sight loosen. I noticed that once the set screw was backed off I could move the back sight by hand. All the many handguns I owned you had to tap the back sight to move it and then you locked it in place with the set screw. I would like to hear from only those would have actual experience with the cz 75 if this is normal for a cz.
Thanks in advance.

it's very normal , the only not great thing about the shadow , when you get it adj , lock tight it

Happened to mine too. Knocked it back into place, put some blue locktight on it, and haven't had a repeat yet (2 yrs now)
