Hi, I’m a new member. This is my first post. Thank you for your help. i’ve had this pistol for three years, but have not used it in about two years since I’ve started using it again, it’s been cleaned oiled and everything looks good, every time I take a shot I have to rack it and an fired cartridge comes out and then it’s ready to shoot again very frustrating out of eight rounds only four get shot. Any suggestions?ps it shot PERFECTLY before.
