I found a licensed Airsoft replica of my carry pistol, a Taurus 92.
I've taken to indoor practice and force on force training with it (all safety precautions are taken).
It's safe to do this; the speed is only 137fps and we wear goggles. I bought the kid (18 years old) a full auto so I could go up against superior firepower.
Other than finding out that those things sting if I'm hit in the right spot, I've modified some of my tactics. For example, I don't use two handed aimed fire nearly as much but get good hits. I also tend to move away from his spraying because I don't want to be stung. This is usually done on a backward angle while returning fire.
What led to this was a reintroduction to the 'game.' A friend let me use an M16 replica and I drilled the kid in the chest and when he wouldn't drop the pistol I automatically gave him a burst in the face (oops!). He was fine though.
I do also find that all this reiterates how quickly things happen.
Thoughts? Anyone else do this?
