If I had to get a 40 in the same size, although 2 oz heavier it would be the Kahr CM40. But personally would see no benefit over the9mm cal especially in a small Pistol especially since the 9mm has a proven track record and improving all the time. And of course the Kahr CM40 is already available. And while the Kahr CM9 and Sig 365 are mild shooters, the recoil would increase significantly by about 4-5 lbs. That would change the smooth shooting dynamics to a not so friendly shooting gun and turn in a smooth shooter into something unnecessarily a unpleasant shooter. JMO
