I just bought a Polish? surplus military flare gun; aka H&K knockoff. The hammer remains in 1/4 open position (firing pin visible). If I pull the trigger and push the hammer with my thumb, the firing pin would strike the primer. If I cock the hammer and then pull the trigger (dry fire), it doesn't seem the the pin would extend to the primer. My question to anyone that has one-is it normal for the hammer to rest in the 1/4 open position with the pin fully visible? Thanks for any help!
