A Glock 23 would be my suggestion. Thats the .40S&W cartridge.
Even a compact .380 will do the job and they make lots of noise, but for put down power I suggest a .45 and Glock makes them in several sizes, the 1911 style frames are the best in most peoples hands, the right angle and such, oddly enough I found my S&W Sigma a natural fit though its a 9mm, my best handgun, most accurate is the Sig Sauer P220, that is when I’m serious, though the Glock 21 also in .45 is right alongside it. The Sig is wonderful. My hands are big so I can handle double stacked frames.
Thanks, I will check this weekend. In California, how long it will take to get gun.
