I am going to get the Q5 Match. Here comes the dumb question part...is the Q5 Match a PPQ M2? Meaning, if I need mags I can buy mags that say PPQ M2. Even here, there is no Q5 Match forum. Is that because it is a variant of the PPQ M2? If I buy a holster designed for 9mm PPQ M2, will the Q5 Match fit? I know the addition of the optic might make a difference, but an optic free Q5 and an optic free PPQ M2....same holster?
