I'm about to buy an XDM 40 full size. I was pretty sure this was the route I wanted to go but I am having second thoughts after shooting my friends G22. The price on the XDM was 549 and the G22 was 529, the xdm comes with a few more acessories. So if you own one or have experience with either please comment. I was particularly interested in the lifespan of the XDM I have heard of people shooting thousands of rounds out of Glocks and they still run strong.
