These are all the reasons I wouldn't want one on a carry gun, and $300 is too much money for a plinking accessory. That said, if you decided on a laser, something like a Crimson Trace would at least solve two of the problems: The equipment replacement and the activation switch issue.
+1. Those are the very reasons, as much as I liked the idea, that I could never swing a lasermax. The factory-CT on the 642 doesn't feel obtrusive. Sadly, the ones for my G30 just make it feel too fat in the grip. Like the g30 grip starts out svelte! :rolleyesedit:
