The Ruger LCP is a nice gun, small, comfortable to carry, and all in all, not a bad little gun.
However, the issues will largely be discussed surrounding 22LR ammunition. The potential for misfire/squib rounds is much higher than for centerfire ammunition - it’s one of the reasons they developed the .25. Then there’s the amount of damage a 22LR causes which means that shot placement is much more critical - and this is where the gun comes back into play. Can you, under stress, reliably get good shot placement sufficiently good enough to make the 22LR effective with the LCP?
I’m 100% for carrying a 22LR EDC if you don’t have another option that will perform better. It’s better than what you left at home, but is it the right weapon for you and your situation will be determined by a lot of factors that don’t always translate well to a forum discussion.
However, most would suggest the LCP in .380 or similar over the 22LR though recoil would be much higher.
