For a carry gun in hot climates I agree, the Kahr PM9 is a
great pocket gun.

A hammerless S&W airweight with a Barami grip is fun as well.

In colder climate conditions with light overclothes a smaller 1911 IWB with a "clip it" attachment can work if it rides properly.

With overclothes a "inside the belt", outside the jean rig for a big semiauto works well.I like safeties on my guns to avoid reholstering surprises ala Glock so the HK compact, Browning, and para-ord limited get the nod.I find the reworked Para only reliable with ball loads.Soft points need not apply.Thus the Browning and HK get the usual carry duty.A Surefire flashlight and additional mag can go elsewhere on the large belt if one feels so inclined but thats getting HEAVY.

It always helps to "be prepared".A man needs to have options.
