I train with a blowback green gas 1911 The slide does cycle as well as the mag changes include the airsoft BB's as well as a new green gas refill. This gun is the same size and weight as my 45 cal 1911. I was also surprised with the accuracy of these guns at distances under 50 feet. The recoil is similar to a .22 cal in a full size 1911. I recommend these guns as a safe way to train at home indoors. I shoot in my garage several time a week when it is to bad to be outside.
