I have the XD 3" subcompact in .40. 9+1, slightly bigger than the Kahr. It's snappy, but no more than a FEG PA63 or PF9.
For conceal carry .380s in warm weather,I rotate between the S&W Bodyguard 380 and Beretta 84FS.But lately,it has been the 84.Not too big or small,not snappy,conceals well,and holds 13 +1 ro of Hornady Critical Defense.For 9mm,I carry the Nano with 8+1.When I carry the Bodyguard,I keep a spare 6rd magazine in my pocket.
