It sure seems petty but it is still bothersome to me. The right thumb safety is very loose but still functional. I do not know how it happened and I did buy the gun used. I've taken it to the range once and I went through 250 rounds with zero FTF's or FTE's. So my questions are;
Can you replace these on your own? If so, where do you get the parts and how hard is it to install?
If not, how long is the turn over time typically with FN?
