With many things in life when you only know one method or system it can be very easy for you to be good with it because of the practice. However there is a situation with the Model 70 safety that should have been done different although I have no real complaint with it as it is.
When gripping the pistol grip tight in a panic it is much MUCH easier to flip the safety off with your thumb while able to grasp the stock tightly.
It is a little more difficult with the index finger pulling it away from the trigger or,.... by using the thumb and having a loose grip on the rifle stock for that moment.
This is "grasping at straws" to find a bad feature of the Model 70 in my opinion. Truth is the safety would be better placed on the other side. However I have not struggled all that much with it located as it is now.
