I was shooting my glock 19 while a guy next to me was shooting the XDm 5.25 comp. He let me try his after I was done. I since sold my two glocks. That is a GREAT gun! Congrats, you'll love it. It opened my eyes to guns other than Glocks and I can tell you there is a life outside the glock world....but, I still love glocks too! ....oh yea, his was the 9mm.
I "handled" one at Bradis today ..... VERY NICE ...Holy $h!+ batman, a Glockie admitted that there is other tools in the box besides a glock. What's this world comming to?
Just kidding, I want a xdm 5.25 as well. I'm jealous. Hope you enjoy and don't forget to post range report for us less fortunate. And I'd go with the 9mm simply for the cost of shooting a lot.
