A lot of great responses posted above. They’re both great guns and so is the Veteran mentioned above. If you have the money, buy the Impact, you won’t ever be wanting in the future. I love the Impact, it does absolutely everything I want it to. There is a huge misconception that if you buy the Impact, you need to continually fiddle with it. That’s not the case at all. Buy it, if you’re fine with the way it shoots, leave it alone. If you want to adjust it later, try a different tune, try a different caliber or try slugs down the road and have plenty of power to push them fast, you’re good to go. It is certainly more adjustable than Dreamline too. What hasn’t really been talked about here is the Impact’s adjustability, modularity, super shot count, huge magazine capacity, plethora of aftermarket accessories, on line support, videos tutorials, and thousands of people that are very familiar with the Impact and can help you almost immediately with any question you might have. I know we always tend to hear the complaints or bad stories about the Impact and very rarely do we hear the praises and great stories, but consider this…The Impact has dominated the market for years and the demand for them is stronger now than ever. It’s because the Impact offers things that no other gun does. The magazine capacity I mentioned above is one of my favorite features. I can fill my 580cc bottle to 250bar, throw three 28 round magazines and a couple speed loaders in my pocket and I’m good to go for a long time! A lot of features like that get overlooked with the Impact but are what make it great. Obviously, the choice is your but having shot them both a lot, I would suggest you buy the Impact M3! You’ll be happy with either one! Good luck with your decision, be sure to let us know what you decide and share some pictures of your set up when you get it!
Have a great afternoon!
