We basically have the his & hers.
Wife has the 3.8 and I have the full size. We camp in big bear county (not huge bear country), and my 1911 is too big & heavy. A long hike a few years ago made me realize I wanted something a little lighter. And the wife wanted something more powerful than a 9mm. I tried Glock, but the G20 grip is too big. S&W was next, until my wife got her gun first. Then I figured I might as well get the XDM. I got the 3 extra mags, so 5 total, and she can use a couple of mine if she needs to.
Last week I ordered my free RDS plates for each and they arrived in 2 days. Better than AMZN. Now I just need to track down the right screws.
I really wasn't looking for another caliber to keep track of, but what are you going to do?
