Update
Just brought the Mak home and gave a cleaning, something I'd recommend for any "new" Mak. Mine had a year code of 19 making it of 1979 manufacture. The pistol was clean except for the spare magazine which had an abundant amount of grease inside. The spare mag had been used as evidenced by marks on the follower.
The pistol itself has some holster wear, not enough to see in the store's lighting, but enough to see on my bench. Regardless, it's still 95%+ and in excellent condition. The bore was very clean, as in never fired clean. But the holster wear says it isn't new, the trigger feels pretty good but the thumb safety/decocker is real tight, as in brand new tight. I'm getting mixed signals as to how much range time it's seen; carried a lot and shot little comes to mind.
Still waiting on ammo.
