Trigger locks are of the devil. Whenever I buy a gun, the first thing I do, sometimes at the gun store, is I throw a frozen rope touchdown pass to the trash can with the lock and/or keys to the internal lock. I don't believe there is any excuse for owning any trigger lock. If you can't trust your kids around a gun without a trigger lock, then you can't trust them around one WITH a trigger lock. What is the point of keeping a gun around if it has a lock on it? Stupid wal mart and Big 5 have these ultra cheap plastic EXCUSES for locks which still allow the trigger to be pulled. A year ago I bought a nagant from Big 5 and this plastic lock slopped around so bad I could have loaded and fired right there.
