Hello all new member here, new to Glocks but no stranger to Firearms. I recently purchased a Gen 4 G-19 after I was sure I would never own a Glock! I am a huge fan of FN and Spring Field. I fell in love with the G19 and it was quickly becoming my favorite and my EDC. Took her to the range and had malfunction after malfunction. The slide would get stuck 2/3 the way back and the spring would pop out the front. It was almost impossible to hand cycle the pistol and malfunctioned after every shot, each time the slide getting stuck 2/3 open. Taking her apart I find damage in the plastic behind the right rear rail. The plastic is chewed up and the metal rail is separating from the frame. Called Glock, they are making it right, so far great customer service! Here are a few pics of the damage. Any thoughts or feedback would be appreciated.
