Barnes 115 gr TAC-XPD +P or the new Winchester 147 gr Ranger T-Series are fine in 9mm, even in short barrel weapons.
Both expand to .70 or more in 9mm and penetrate through outer winter garments, and then remain where you want them. Gel tests out of both my 226 and 938 confirmed that. The ranger 147 was especially good in the 938.
I was always a .45 shooter, but am now 73 and want something I know I can still control 20 years from now (except Mrs. Strac of course, where there was never a chance of any control by me... not that is it needed....)

Great video of the expanding wound channels for both at that website.
Be well.
Controlling your shots is always important, I have a little .22LR for my better half. it’s right there next to her night stand. I wouldn’t want to get in a shoot out with her when she got that little bugger, I’ve seen her shoot it too many times.It’s great for interior home defense because it won’t penetrate too many walls and hit the grandkids
