Wow.....This thread has don pretty well. Since I started it several months ago. I have sold the 642 because ...try as hard as I could I just didn't care for shooting it and finally unloaded it.
In the meantime my little 640-3 with the C-Trace go to the range a couple times a month. The 640-3's place is on the night stand beside me every night.
Good shooting,
