I hate YT, but don't know gun reviewers on BC. So, go there and search on Honest Outlaw, Hickok45 or TFB TV. There are numerous good gun reviewers. Pick a Glock 19 (9MM) or Glock 22 (40 Cal), or a S&W M&P 40 or 9mm. These are the 2 most common LEO calibers and brand of hand guns. Reviewers have zero reason to fake recoil. Plus many are very well trained. The guy that shot is LEO or some sort, hence, he should be as well trained as most these reviewers. Hickok45 is an old, retired teacher, but one of the top reviewers. So, you get a range of "pro training".
