Suppressor height sights

I just got a Glock 34 MOS and plan on getting a C&H plate as well as a Holoson 507c. Until then I wanted to get Ameriglow suppressor height sights so when I get the optic I didn’t need to change the sights out and don’t buy 2 sets of sights. What are the challenges or disadvantages if any of using suppressor height sights? Other than a greater offset.
