Gents, I also own and shoot an XD in .45 caliber, A SWEET Pistol for sure, Made it even better by mounting a VIRIDIAN green laser to the front of the pistol, Green is the way to go, Can be seen in the Sunlight when Red disappears.
Sighted mine in for 25 yds and it is awesome. I am Proud to be an owner of the best thing since a 1911.
Also own and shoot a Classic Browning 9mm Hi-Power it also is a Great pistol, Love to shoot it also.
Enough for now, Regards
