I need to grab the original LAPD video that's being discussed vs trying to have an opinion based on that chopped version. The copper with the Beretta 92F is not a youngster. She's a FTO (P3), and that looks like four service stripes on her forearm ... so, 20+ years.
edited to add: SoCalDep can correct me, but IIRC some deputys at SEB (their full-time tactical element) were actively using 92Fs long after the issue pistol changed.
@SoCalDep - I'm saving that post. Excellent thoughts on what trainers should be doing. Thank you.
