I used to recommend GemTech to all my customers and had really good luck with all the different types of cans they made. Customer service was stellar and I had one customer who ended up with an extra suppressor because they found the problem with the one he sent back for repair was their fault. Excellent people and service. In the last year or so things started falling off. A customer ordered a suppressor and we kept getting the old, "its in transfer" message but there was no serial number supplied and after a year we canceled the order. At about that point we found out S&W had purchased the company so maybe the issues were caused by the coming purchase or something of that sort. A number of key people were replaced and we have seen a marked drop in service. I won't recommend GemTech to customers anymore sad as it makes me to admit. I'm sure others have had different experiences but from posts on various boards I'm seeing a lot of stories like the OPs and my own. The suppressor market has gotten a bit cutthroat and people expect more for their money. Marketing has gotten involved with decreasing performance while making the cans look "cooler". Tough time to be in the biz.
