Those are actually subcompact. I assume most manufacturers offer such models. Examples are: Taurus, Canik, FNH,....

I would look for something that has taller sights that can be used as backup to optic. One example would be FN product. This is nice because you do not have to waste extra money like you will if you buy a Glock. To add insult to injury standard Glock sights are plastic.
Another example is someone looking for very good trigger on plastic framed striker fired pistol. One saves by buying Walther PDP in the first place.
