The 442/642 are excellent choices. If you are already a seasoned handgun shooter I see no reason not to get an Airlite. I have a 340sc .357 which would be fine loaded with standard pressure .38's or +P's. I carry medium velocity .357's in mine. The light .357 gives you a 2 caliber choice and is so light you hardly know it's in your pocket. The 340PD is a bit heavier due to the steel cylinder but is also a great choice. The Airlites are more expensive due to the scandium and titanium used which are expensive alloys and are more difficult to machine. Practice and familiarity with an Airlite erases all the concerns people seem to have with these guns. Either they have one and don't shoot it as often as they should or they don't have one and "assume" they are more difficult to shoot? Beats me. Of course as I always say what's good for one is not always good for everyone.
