Hey guys, I know this thread is 3 years old BUT, I JUST had this happen to my Taurus PT111 G2 on yesterday (April 21, 2018). My PT111 is 3 years old and I bought and installed the lakeline recoil spring in mid December 2017 to possibly help resolve FTF and FTE issues I was experiencing. I have maybe 1000 rounds through it since I have put it in. The ends of the spring are flattened as needed to make it seat right on both ends in the gun slide and on the guide rod flare on the other end of the large spring. I have already contacted LakeLineLLC about but I did want to others to know that is issue still happens. I will be working with LakeLineLLC to see if we can figure the issue on why the large spring end did make it through the hole where the spring is supposed to seat in the hold of the slide. So, chalk this one up to another more recent happening even with the statement from Konyo312 stating 'there have been some changes'. No offence Konyo312, I'm merely indicating that any changes by LakeLine may not have helped this issue as mine is literally a more recent.
