Ditto about Bills GS. Don't buy a .22 as a self-defense weapon. Rent it, then move on. .22's are best used for competition target shooting and assassinations at close range. Consider this:
"I have serious reservations on using the .45 ACP on dangerous animals. While working for the sheriff’s office in 2001 I was attacked by a large angry rottweiler that soaked up round after round of 185 gr hollowpoints. In the end the dog had been hit eight times, chest, shoulders 2x, upper front legs, and snout before he backed off. None of the bullets made full penetration. If you believe something is knocked off its feet when hit by a .45 Im sorry it just don’t happen that way. I was a tried and true .45 guy until that day. This did motivate the department to switch to a 230gr +p round but at this time there have been no other shootings with the new ammunition.” [Emphasis added.]

I've owned S&W .38/.357, Colt .45 ACP, Ruger .45 LC/.454 Casull and CZ 9mm semi-auto. Ruger revolvers and CZ semi-auto's are my preference. The CZ P-01 has passed some of the most
rigorous performance tests in use.
A
first gun should optimize reliability and situational applicability. The most reliable choice is a revolver. They never fail to feed or eject properly, and they never jam. Just be sure not to drop them, because bad forcing cone/chamber timing can cause hot lead shavings to come out the side of the gun. To apply well to multiple ranges, but still be concealable, choose a barrel length between 2.5 and 4 inches. The standard/magnum combination is necessarily a little bigger, and hence, less concealable, but if it's your only carry weapon, it's application versatility triumphs. If it's going to be your secondary weapon, and concealability is that important, consider a 5-shot capacity.
With proper (advanced) training and practice, you can win a gun fight with two, close-range opponents, provided that:
You keep your nerve and concentrate on shot placement.
You start your DA trigger pull between targets so that it coincides with secondary target acquisition.
I highly recommend Massad Ayoob's "StressFire" Vol. I of Gunfighting for Police: Advanced Tactics and Techniques -- ISBN 978-0-936279-03-09.
Also, check out the Ron Szpond technique. There are different caliber combination choices to be sure. Just be certain that both guns are equally accessible, and that the smallest caliber (smallest recoil) gun is in your weak hand.

The smaller projectile may have less foot/pounds of energy, but they generally have higher sectional density; hence, better penetration.

"The heavier and more narrow the bullet is, the higher its sectional density will be." "... [A]ll other variables being equal, a bullet with a higher
Sectional Density will:"
Lose less energy and speed in flight
Drop less on the way to the target
Penetrate more effectively into a target
Penetration is a determined by a bullet’s construction, sectional density (mass/diameter) and momentum (~mass*velocity). The greater the SD and M, the better the penetration (with appropriate bullet construction as a given here, but is a discussion topic for another time).
