Re: 2400 for 10mm?
My favorite in 10mm is BlueDot but over the past couple of years I've been putting a pound of this and a pound of that on the shelf just in case something like what we're experiencing now happened.
Red Dot, Green Dot, Blue Dot, Unique, B/eye, 2400, 700X and 800X are all useful.
I have all of the above and shot all of the above from my 10mm, some obviously work better than others. But the kicker is that I have options, even the worst of them (Red Dot with heavy bullets sucks) is still plenty to defend myself and my home if the need truly arises.
OP: Anytime, let me know if you have other questions, I have a LOT of 10 data that I can share.
