Mr. Harry took the time to answer my email questions. And he answered frankly, even about the negative aspects of some air guns. He handled the money transaction smoothly, as one item on my order was out of stock. My two orders both arrived on Thursday after my purchases on Saturday and Monday. Review of his web site shows that he has taken the time and effort to test many of the air guns that he sells, and he understands how they operate. Technical information is very difficult to obtain on the internet, but he has it to offer. My transaction was very positive and topairgun.com will be at the top of my list for my next purchase.
