My standard XDM Elite 4.5" arrived last week, and took it to the range a few days ago. I didn't put as many rounds through it as I normally would due to ammo scarcity, but I shot enough to get a good feel for the gun. I have large hands, so I really liked the feel of the long grip. I'm not usually a fan of flared magwells, but the grip on the Elite is long enough that no part of my hand was even in contact with the magwell. Recoil is pretty mild and the gun is more accurate than I am.
It may be a lack of sophistication on my part, but I didn't really notice any profound difference in the META match trigger and the traditional XD trigger when firing. The trigger is good, but I never had any problems or issues with the standard Mod.2 triggers. More discriminating shooters may appreciate the META more than I do.
I didn't put enough rounds downrange to give a detailed report on reliability, but it ate 100 rounds of assorted 115 gr and 124 gr FMJ from my leftover pile without any issues. I paid around $475 OTD for the Elite and feel that the gun was worth every penny. I probably won't use the Elite as a carry piece, but I strongly suspect that it will become my go-to range toy.
