Shot my PPQ Q4 yesterday with no problems. I don't have a holster yet. Feels just like my PPQ M1!
I have a Q4 TAC with a DeltaPoint Pro on it. I’ve ordered a holdster from DARA HOLSTERS & GEAR. Haven’t seen it yet but they custom build them at reasonable prices to suit this model with or without accessories. Mine is the: Custom Kydex Optic Cut OWB Holster. Their customer service is great if you have questions.How many out there have Tac Q4’s, and what holsters are available and any issues good and bad.
