I own two PPQ one in 9 and the other 45. This gun just fits me I sure wish they would make this platform in 10mm It would be a daily carry for me. Probably a Longshot but it's ok to dream.

All you can do is pester them and see 

Squeaky wheel gets the grease ...........

I like the PPQ (and P99) as well.  Curious how the build of the 45 compares to the 9/40 and whether it would be up for the 10mm.  Would be great if it could and I'd be in.  The other polymers I'd like to see in 10mm would be the HK MK23 and USP Expert.

The slide is larger I think with the proper spring the platform would do just fine but the Germans are really thorough engineers so if they designed it the gun would function and hold up.

I'd buy a 10mm PPQ. I was just looking at the .45 PPQ on the Walther site and was wishing it came in 10mm.

I briefly owned a PPQ M2 in 40 for a few weeks. The trigger was fantastic when dryfiring but never shot the gun and swapped it off in a fit of stupidity.

I now have a CZ P10C in 9 that also has a great trigger for a striker fired pistol and it may become my nightstand gun after a few hundred rounds. It points well and the grip is better than any Glock, but not as good as the PPQ.

A 10mm PPQ M2 would be a nice piece.
