I now have about 250 rounds through my gun. Not a jam yet... accuracy is good... for a "Gun Noob" like me HAHA. I can feel my trigger getting lighter and crisper - and I thought it was great out of the box!
I really think I have something wrong with my spring however. After comparing it to one in the case at the store.
Glock is going to send me a new one, but said it could be a few weeks...
I have shot XDm's - and they are great guns also. I think either is a fine purchase. To me it just boiled down to what fit better in my hands. I actually prefer the grip angle of the Glock over the XDm - it just seemed more of a "natural point" for me. I also liked that the Glock was a little smaller and stream lined.
I'll post again with an update about how this all turns out. In a week I will be shooting a buddies XDM in .40, which I have shot in the past. I am curious to see if I notice a recoil difference with the dual spring - and lower bore of the Glock. People in other forums refer to the recoil of the Gen4 as more of a "push" than a "flip"... I kind of noticed that at the range tonight, but have nothing to compare it against... and I am a novice/noob.
