I too had the same reaction late last week when I did the spring swap - used a 16#. The DA is much better, just got back from the range and it was still a tough pull though. Maybe there is a 14# spring in my future.
I was glad to see that there were no premature mag drops though. S&B 95gr FMJ
Just returned from the range this morning,16lb spring made a heck of a difference,I'm very happy with the DA pull and accuracy. Still is a kicker, also shooting SB 95grains with no mag drop problems either.
Ive orderd two more p-64's, and may try the 14lb in one? Right now the 16lb is good for me.
