I would recomment that you never dry fire an Encore or a G2. The firing pin will break. It may last for a few times or a hundred but it will break. You should order a least one or two spare firing pins from TC. They are easy to change out but the pistol is useless without it.
Maybe I just had a bad pin, but it broke after a half dozen dry fires. The other way to go would be to get or make a snap cap for your barrel.
Good luck and think about getting a trigger job. The Encore trigger can be taken down to about 24oz safely.
