I didn't know you had a PDP. I'm still waiting for IOP SD Pro's to show up, I already have the Walther suppressor height sights for the RMR/Holosun, now just need the gun.Lucked into a giant footlocker of Bulgarian AK-74 mags. Bought everything.
Also bought more mags for my Walther PDP from Gun Mag Warehouse. Just love this pistol (NOT for beginners).
