I am turning 21 soon and plan to get my CWP, initially after looking at a few handguns i have been drawn to the Springfield xdm 3.8 in .40 cal. But have also been recommended to look at the glock 22 or 23. I have shot neither of the guns. just wondering what would be a good first handgun that wouldn't be impossible to carry in some situations. Other suggestions are welcome but i would prefer a .40 cal over a 9mm.
