.22lr is a significantly underestimated round (far more deadly than many people would lead you to believe). That said, it's by no means a first choice SD caliber but it is what it is today and I would not feel the least bit uncomfortable storing some .22lr ammo and making it a key part of my 'repertoire' .38S&W SP. being my main CCW or HD 'bump in the night' gun.
