I carry a 442 or a 638 or a 640 daily, in a Lobo enhanced pancake holster on a Lobo belt. On those rare occasions when I decide to take the 2" 64, also in a Lobo enhanced pancake, I'm always surprised at how heavy it is. (I'm also surprised at how easy it is to snag the hammer on a cover garment when I practice drawing from concealment with it at the range.)

I'll usually go ahead and carry the 64 for the day, but I'm always glad to put one of the lighter guns on the next day. And glad not to give a thought to snagging a hammer should I have to draw it.
