I've had this M1 a long time. It's a 1954 Springfield. I decided for whatever reason to put in a new op rod spring. So, I bought an Orion because they have a great reputation.....OMG, that spring is strong. I cannot push down the follower with an eight round clip with one thumb. So, I used both thumbs and did not hold back the op rod handle with my palm.......when it clicks the bolt just comes forward and rests on the top round (you have to give a little tap for it to go into the chamber. Okay, but am I in danger of getting a double M1 thumb?.....I guess it's fair to add that when I was in the Army and 18 years old, I had no trouble....but now I'm 83 and my hands are not strong. any suggestions?
