I agree with others. I have handguns in .22/.22mag, 9mm, .40 S/W, .38 special/.357 mag. I have target, HP, personal protection and shotshells (in limited quantities). With the latest ammo rush as evidence, there have been some places I can find one but not other calibers. That way I do not have all my eggs in one basket, so to speak. I will always have something to maintain my CC and personal protection. I have 4 handguns I can use as CC covering all the calibers except .22. In addition, I have a 12 ga I can use for home defense if needed. I have rifles in .556/.223, .30-.30 and .22 if I need to keep the BG at distance from me. I constantly am trying to replace any I use at the range. With this duplication, I can ensure I won't be helpless because I only have one caliber and can't get ammo. If you downsize be sure you have more than one caliber you can shoot is my recomendation.
