Depends upon the need
I am 51 years old and for me, it depends on what I want to do with the handgun.
For self defense, my choice will almost always be a semi-auto. I like the metal framed BERETTA 92, 96 and 8000, as well as the SIG 226 an 229.
On the other hand, that piece of plastic sure feels better on my back at the end of 8, 10 or 12 hours (the other day it was 18 hours). GLOCK convinced me that there is no disadvantage in a plastic frame. My experience with the WALTHER P-99 has only confirmed this.
So what did I wear the other night, a SMITH&WESSON model 38 in a Thad RIBKA pocket holster. It just comes down to what fits the situation best.
My first issue gun gun was a S&W model 13 with a 3 inch barrel. I could not wait to switch to the GLOCK 19. I had 2 1/2 times the rounds in the gun nearly a box of ammunition on my belt.
Did I shoot any worse with the GLOCK? No, my qualification scores were the same. Did I shoot better with an L-frame S&W model 681? Yes, but no better than when I used my SIG-226.
Did I give up power for capacity? No, my agency issued .357 magnum 110 grain JHP ammo with a muzzle velocity of 1,300 fps. They also issued 9m.m. +p+ 115 grain JHP, also with a velocity of 1,300 fps.
In the end, the lighter weight, greater ammuniton capacity and equal power led to me carrying a semi-auto. Still, I do carry that 5 shot .38 from time to time.
