gwiley Posted October 30, 2019 Share Posted October 30, 2019 Hello! New here and so far from what I've read seems like a *great* group of people! Can't seem to find this answer anywhere. I have a CZ Shadow 2 Urban Grey and I am thinking about changing out the sights, but even though I have a set of allen wrenches, both standard and metric (about 8 sizes of each), a wrench near the size of the screw on the rear sight is too small and the next bigger one is too large. I've tried emailing CZ support about it, but never heard anything back. Any help would be greatly appreciated! Thanks in advance! Link to comment Share on other sites More sharing options...
George16 Posted October 30, 2019 Share Posted October 30, 2019 The rear sight uses a 2mm Allen wrench. I just double checked it with my shadow 2 to confirm. Link to comment Share on other sites More sharing options...
gwiley Posted October 30, 2019 Author Share Posted October 30, 2019 Hmmm, I'll double check when I get home, but I'm sure my set has that and it didn't fit. Thanks for checking! (BTW, mine *does* have factory rear sights- am I safe to assume that all Shadow 2's have the same rear sight?) Link to comment Share on other sites More sharing options...
gwiley Posted November 15, 2019 Author Share Posted November 15, 2019 Sorry for the delayed response- I tried the 2mm Allen and it is too small. The next size up is too large. Any ideas why I would have an odd screw and what it could be? Link to comment Share on other sites More sharing options...

cbrussell Posted November 18, 2019 Share Posted November 18, 2019 Believe it or not, there is a 2.5 mm wrench. I forget what I needed it for, but had to purchase one separately. I think I bought it at Wiha Tools. Link to comment Share on other sites More sharing options...

All four of my metric Allen key sets (two folding types and two individual key sets) have one. Link to comment Share on other sites More sharing options...

One is too small, the other too large. So weird. Don't know how I'm going to get it off to replace it. Link to comment Share on other sites More sharing options...
