I bet I'm the new poster you're referring to, eh jfh? I hope I'm not bringing up a overworked subject, but I was searching and just not finding the answers I wanted, I think I now have everything I need to make an informed decision and I appreciate everyone's input alot!
It's between the 405 and the 105...do I want to spend $75 on a master switch?..., It seems like it could be handy, however jfh, I'd be interested as to why you don't see the need for a master switch. As I have yet to handle any, I can only guess, perhaps it is the placement of the on button that makes a master switch unnecessary? I suppose if I want to practice without the laser I can always just swap the grips.
Thanks again everyone! I'll post a pic when I get it all figured out. ;-)
