First off let me say HI and I'm now a proud owner of a slightly used R9s. I was very excited to get to the range and prove to myself this would make a reliable carry gun. It did that and more. I was amazed at my groups (now I was only shooting 7 yards) up until my hands started to fatigue. But I did put 40 rounds of Speer GD 124 grain through it and she ran like a champ. I'm not a rookie at shooting by any means however everybody can have a lack of concentration. Mine happened around the 30th round. Trying to concentrate on the sights and the little pup bit me...lol.
