Do I need to rethink my EDC?

[OlBill]

I usually carry either a Ruger LCR in .38 Spl with 135gr Gold Dot Short Barrel loads or a 9mm Shield with 124 gr HST loads. However, I may need to rethink this. I'm fairly small (5'6", 160 lbs), getting along in years (75) and because of these factors I'm wondering if I shouldn't go to something more powerful. At my size and age, I'd hate to go hand-to-hand with a guy 25 years old, 6'4" tall and 250 lbs. For me, the gun is not the last resort in a self-defense situation, it's the first resort. So I'm thinking about a heavy-loaded .44 Spl, a .45 ACP, or a .357 Magnum.

What say ye?

Thanks,
