I would have said the M2.0 compact until I saw the threaded barrel / suppressor hieght sights. With that as a requirement, I would go with the CZ P-07 with those options already on it. My local shop, Lone Star Defense & Arms, actually has one that I keep checking out everytime I go in there.

Well, the PPQ sights actually are not suppressor friendly, which is extremely confusing to me. Why supply a threaded barrel, but not equip it with taller sights.
I imagine I will eventually replace them, but to be honest, I rarely use my suppressors. I got my first one about 8 years ago, and usually only take them if I am going to be shooting with someone who has never shot with one before.
