Hello everyone, picking up my first polymer - striker fired pistol tomorrow. I couldn't be more excited. I have never had any interest in polymer for firearms, but after some thorough research and intentionally trying to stay from Glock, and some of the common American manufactuers...(nothing against them...just want something a little out of the box) sort of speak. I think I'll be happy with my choice. It was manufactured in 2013. It has about 300 rounds or so down the pipe and in virtually new in box condition with all original paperwork included for $450 and a 50 round box of ammo. Can anyone tell me if the 20 round magazine for the P99 fit in the PPQ? I'm about ready to order one?

Yes, the 20 round P99 mags will fit.
Baby dessert eagle magazine also work in the PPQ M1, if you can still find them.

Item# MAGFA915

Yes the 20 rounders fit fine.

Be careful with the baby desert eagle mags with regard to the part number though. There are 2 versions.
Make sure you get the exact part number as listed by the above poster. The other version doesn't fit at all. Trust me, I found out the hard way.
