IDK, but if a little lady like Brenda can learn to handle the recoil of a .500 S & W most any motivated man could too.
Back in my 20s I taught about a dozen women to shoot handguns.
The majority handled full house .44 mag by the end of the first session.
I always started with .22, of course, and simply moved up in power to .22 mag, .38 spl wadcutters, etc., thru .45 acp and finally .44 spl and mag.
I never told them what they were shooting, just handed them a different handgun; at the end they were uniformly stunned that they had been happily DA shooting a .44 magnum.
Women generally have no preconceived notions about guns and don’t imagine themselves to be instant Dirty Harry, so they listen and learn.
