Query: Not pleased

I recently bought the bt-200 expecting great results. I had seen a lot of publicity in trade magazines and was excited to see how well the gun worked. The first problem I ran into was trying to load 1 9/16" 18 ga. porter cable brads. The clip jambed and wouldn't close. So the gun doesn't accept any brad up to 2". Then I loaded the 2" brads that came with the gun. Once I hooked up the air, I noticed that the trigger leaked air. Then I began fireing the gun at different air preasures within its working range. I had a miss fire of one out of every five shots. I bought the gun with a litte scepticism because I had problems simular to these with bostich staplers. I returned the gun and got the porter cable. No problems.
