I do frequent self-defense/tactical training with my 5.7. I prefer an IWB holster and "appendix" carry position. That thread protector on the end of the barrel gets very hot! I don't use any barrel attachments and so have no need for the threads on the end of the shroud.
I have tried the FN Five-seveN and did not care for the design. I also tried the Ruger 57 but I found that the S&W has a much better trigger and has even less recoil.
I do use a red dot sight (Holosun HS507Kx2) as I have some eyesight problems.
