The T9 is still a fairly compact pistol. If you like the HK P7 then the T9 should be attractive too. These two guns are very similar in many ways; same weight, same barrel length, slim and concealable, simple to use, simple takedown, nice trigger, polygonal barrel and 8+1 capacity.
Much as I like the T9, my personal Kahr favorite is the TP9. Same gun but with a lighter frame. The T series feels really good in my hand. The full grip and longer sight line are all more appealing to me. I like the bigger Kahrs more than the tiny one, but that's just me.
