CZ P-09 Front Sight Screw Wisdom?

[415Shooter]

Hello friends.

A few questions
Can any of you confirm this post that the sight screws are hex sized 0.9 mm? 

The reddit poster recommended this tool set for working with the sight screws.  Any opinions on the best and best value tools for the job?  I won't be doing a ton of gunsmithing, but I want the right tools for the job.

Since my OEM and the new Night Fision screws are both stripped, any advice on the best way to replace both of them?  I found this product listing and this kit.  If the kit (or any other kit) has what I need, the price point is certainly attractive for future spare parts.  I am also on the waitlist for the factory spare parts kit, but doubt that will help me any time soon.

Thank you!

Back story:

I was excited to start on installing my Night Fision Glow Dome sight set on my P-09 today.




My excitement faded when the hex wrench that came with the set did not fit my OEM front site screw snuggly.  At first, I thought the jerky action when rotating was because of some loctite on the threads.  But after I got it out, I got a better view and saw that it was actually stripping the screw a bit.

Since it was out, I thought I should be good to go with putting in the Glow Dome sight with the wrench that came in the set.  WRONG.  I got it in most of the way and then it too, started to strip.  I pulled out all my hex wrenches and didn't have a good fit for it.  So it's most of the way in and looking beat up.





At this point, I'm hoping to get replacement screws for the front sight and snug in the new sight properly.  Then hopefully things go better with the rear sight installation when I get the sight pusher tool I ordered.

Some people will grab a set of torx bits and find the one that just starts to fit into that stripped looking head of the screw.  The use a small hammer to tap the torx bit into the screw and then turn the screw back out of the sight/threads.

Once you've got the new screw and the right (fits snug) allen wrench you should be ready to install the new screw.  If you use loctite on the screw also use some rubbing alcohol to remove oil/lube from the threads on the sight and the screw and let that dry off (take a few seconds) before putting a dab of loctite (doesn't take much) on the threads of the screw before installing it.

Bump for critical question - Can any of you confirm the sight screws are hex sized 0.9 mm?

Thanks!

I’m amazed at how many odd size screws Ace Hardware carries. I’m all in for supporting sight sponsors but if you ever just need a couple .10 screws to replace, you’ll be surprised what they inventory.

Good point.  Thanks.

You want Wera hex plus.
You'd be super hard pressed to find better hex wrench keys.
