I got my DVC Open in 38 S in March 2016 off of Gunbroker. After firing 3 rounds in a BRAND NEW GUN, it locked up tighter than Dick's hatband. I had to beat the slide off of the frame to inspect, then the slide would not even go back on to the frame. At this point, I couldn't see right through my tears and was thinking that I have just acquired a $3700 paper weight. I contacted Zane @ warranty and he said everything would be fine and to ship it to him. I did, and in about 1 month, I called him to check on the progress. He said that STI was going to replace that gun with a new one. He said that something went wrong with the assembly process. It was not my fault. 2 days later, UPS was delivering to my house as I was getting home from work. Been great ever since. CUSTOMER SERVICE IS AWESOME AT STI!!!!!
