I have and will always be a Glock fan of the Gen 1 ,2,and 3 . I wont go into the gen 4 and 5. But anyways , I was looking at my XD9 Sub Compact and that little frame is extremely strong and well built. I can bend my G26 frame slightly but the XD SC is strong. And the locking block is extremely thick. In my opinion , if the XD would dump the grip safety and LCI it would be an ideal pistol. Here's a picture of my XD9 SC . I haven't wiped it down yet , the Ballistol is still on it rather thick but you can see how stout the frame is built.
