My trip into open was with a 40 s&w M&P CORE with a Fastfire3 3moa MRDS. I also added a threaded barrel with a Carver 4 port comp. This was absolutely the wrong way to go. I had my hat handed to me at every match. What it did teach me was how to find the dot on my gun. I now own an STI DVC Open. I will say that open is fun but EXTREMELY EXPENSIVE. Reloading is a challenge until you find a load that works well for your gun. Then it is just practice. My cost to get into open so far is around $7500.00. This includes two guns, a progressive reloading press with dies and supplies (powder, bullets,primers, etc.) Other than that you need a place to work on reloading. I am sure others will add to my assessment. So you see, it is expensive but for most guys it is a labor of love. Good luck no matter what you decide. Sent from my iPhone using Tapatalk Pro
