I bought a new SA XD .45 and took it to the range for the first time last weekend. All I can say is...wow! The XD is very comfortable to shoot and extremely accurate. I am in no way an expert shot but I had no problems putting together 2 in. groups at 15 yards. All this for under $500!
Congrats on your purchase. I too was amazed at the accuracy of these pistols. I was lucky and able to fire another member's (ATM) XD and XDm during my decision making process. That pretty much sealed the deal. I have 2 XDm's and am looking for the new compact. I tried to like the Glock, but it just didn't feel nearly as good. Again, congrats and have fun putting the lead down range.
