Great red dot sight - Vortex Venom 1x26.5mm Red Dot Sight

This sight came in packages very well. All components protected and instructions are very clear for mounting. The package also came with separate Glock MOS mounting screws and Allen wrench to mount directly to Glock MOS pistols. You will need to purchase blue loctite (242) for the mounting screws that came with the Vortex site.
If you plan to sight in using a bore site, there are plenty of YouTube videos available on how to do that.
From my perspective, being able to change batteries with moving the sight is a plus. The manual and auto brightness options are also a plus that you can activate based on your needs.
I don’t think anyone will be disappointed with this product. I will say the cover doesn’t fit snug based on you setup (MOS, Rail, etc) based on the location of your iron sights and height of the setup.
I have not shot my 34 with this setup yet, but make sure you battery cap is on tight prior to range visit. Some people have indicated light shuts off during firing and this is due to cap being loose impacting electrical connection.
