I have done this for fun. not really training. at defensive distances a good airsoft pistol will be very accurate. I put a silhouette on each wall for practice engaging multiple targets without aiming down the sights aka reflex shooting. It wont do a whole lot for you as far as training goes but its fun and you can gain a small amount of skill. just make sure that your POI vs POA is similar to that of your real gun. otherwise you will be doing more harm than good practicing that way.
Due to several differences of opinion with staff, I am choosing to no longer do business on this forum. Everyone that has a pending order will need to contact me via email at TakticalHolsters@aol.com
