I agree. I had to shift my rear sight ever so little. But, it was an act of god to get it to move. Well, maybe not that bad. But, I did have increase my hammer size and use a bench block. I was going to heat it as a last resort. But, a little more pressure did it. In hindsight, I say just use a hair dryer and get it good and warm. It should melt the lock tote enough and make it much easier to move.
