Thanks!!! to minimalsaint I should be back in the 19 game by Wednesday!!!
After seeing the two tone mix I ordered two more from Vapor Tech, one ss and one brass (copper). The brass was a pre-order, but I got shipping info this morning and both were listed on the invoice....so maybe I got lucky and both will show up??? I wasn't in a hurry since I thought I would be waiting for the brass one and only did standard shipping

.... SC to UT.... so hopefully Friday or Saturday.
So over the weekend I decided to make my own mod to try out one of the ideas I had for my custom 19 mag switch. Which was a brass tab soldered to the brass plate that would bolt to the center button shaft via the hex contact, thus a hard link from the battery to the mod body.
Here is a description and some pics.....sorry kind of off topic, but I thought you might enjoy it.
At first I was only going for a simple non-locking mag switch, but then stumbled into the realization that I could easily integrate a lock (not really applicable to the 19).
There is a brass tab soldered in with a hole for the hex battery contact to go thru. I originally had it soldered on both sides but it was to stiff so I removed one side and things are a little loose so it was causing the button to tilt a little bit so I started tweaking the brass tab so it would sit straight. Then I realized if I bend up the brass tab around the hex it will capture the hex and stop it from turning and voilà I had a lockable switch

. There is nothing to stop it from screwing all the way out, but I'll take it.
I need to shorten the hex and make a delrin top piece, but it's getting close to done.
This is a 22mm switch with the Zenesis Z2 threads (stadard metric 20mm fine thread 20x1.5), the tube is just cheap aluminum. Tubes are really hard to do on my little lathe, but the Zenesis 2 ss tubes aren't to bad $35-$40.
