Thanks,not sure if I personally would like the Dpm system seems its bouncy. I've seen videos where the recoil is less first but too seems recoil the front sight up twice if you watch video close. Wouldn't be against two springs though. 75 bucks is a bit but for some apps it might be worth it. I am all for new tech. I am suPrised nobody has a shock or hydrolic recoil setup that's adjustable. I am going to stick to a solid ss one because it's idpa legal. I really like it and it's fun training, competing and tuning. I wish I could find one every week close by. I made up my mind I'll get the same one Ares has if it fits good.
