Years ago I put a custom trigger in a pre 64 model 70 and it went off when I took the safety off. On close examination I found that the new trigger was larger than the original and had minimum clearance to fit inside the factory trigger guard. With just enough resistance to retard the movement of the trigger when closing the bolt. I threw that trigger into the Roaring Fork river and went back to the stock, military style trigger and never looked back.
Had this issue with a Remington 700 varmint and a Timney. Instead of throwing it in a river I relieved the factory trigger guard with a file until the slightly wider Timney trigger fit the trigger guard. It took maybe 5 or 10 minutes. That gun had the Walker trigger and would fire when the safety was removed if the gun was jarred.
