I went shooting yesterday with some buddies...I had the XDM and they had Glocks. We swapped around quite a bit and ended up informally comparing the Glock 35 and the XDM, both .40 caliber. The Glock 35 is a fantastic gun, and I had rented one to shoot from a local gun store when I was getting interested in guns. I really wanted to buy one before I came across the XDM. They both are approximately the same size and weight...the 35 may be slightly longer - we didn't measure anything. The Glock has the typical feel of a Glock, simple, big and plain. The XDM has the ergonomic design, which was one of the features that sold me...feels great. The recoil was almost the same. The biggest difference between the two was the trigger pull...the 35 had around 5 pounds of trigger pull according to its owner. I have not even bothered to look up what the XDM has, but I know its less than 5 pounds. When shooting the Glock, I kept waiting on it to fire and it took quite a bit more pull to get it to launch a round. Just my little observations - I still like both guns, but I also am still glad I chose the XDM. Later, B P.S., they both hit the targets very well and I wouldn't want to be a bad guy on the other end of either one.
