Hi everyone, My brother-in-law just purchased a P22 for his wife; they were going out to target shoot with it when they had an issue. He called me and told me that when they would attempt to fire, nothing would happen except a "click". He would even try to fire SA - he'd pull the trigger & the hammer would drop, but just a "click" would occur and the cartridge wouldn't be touched. Does the P22's trigger lock feature actually just lock the firing pin? He said he can move the trigger fully to the rear. He also told me that he could not find a key for the trigger lock in the box even though this gun is NIB. Any help would be appreciated, as I have never handled a P22 before.
