Which Height Nite Sight to pick?

[SteveO666]

Just ordered a Glock 34 MOS and getting the Glock Factory Nite Sights as well and I am not sure which Height to purchase.
Per the Glock Store they are available in 6.1, 6.5, 6.9 and 7.3mm.

I understand that the 6.5 is standard for the G34 but since I intend to use an optic at some point would I need a Higher Sight?
Using the MOS System will the Standard Height allow for a co-witness?
Plan on using a Vortex Venom 6moa once it is available.

Please advise?
Thanks in advance.
Steve
PS, Sorry I realize this should probably be in the Optics Forum but it wouldn't let me move it.

Are you sure they gave you the right models? 7.3mm = roughly 1/4 inch. that doesn't sound very high. i don't remember the exact hight of the ameriglo i installed for a friend but it was definitly taller than 1/4" from base to top and it would not co-witness with a venom or fastfire iii. we returned the ameriglo and bought dawson precision sights.

Here is the link to the Dawson sight https://dawsonprecision.com/dawson-p...k-rear-sights/

notice the heights, the lowest is .395". you can call them to get the specific height you need for your red dot. i can't remember the height we ordered.

I was looking at the GLOCK site's store as well as the GLOCKstore.com which state that the 6.5 is the standard height,
https://store.teamglock.com/gun-part...ght-6-5mm.html

http://www.glockstore.com/Glock-Sight-Rear-Steel-6-5mm

Both state 'Standard height on G17, G19, G22, G23, G26, G27, G33, G34, G35, G37, G38, G39 (Including Gen4).' for the 6.5mm
I will check out the Dawson sights
