I've got 2 LCR 38 and had been looking at the LC9, haven't seen one in person yet.
LCR
Point and shoot, if the gun does not break, it will go bang. I've got all the reloading stuff too.
Only 5 rounds, enough for a single attacker but limited for multiples.
LC9
More rounds, quick reload
If the gun does not break, jams are part of normal operation for a semi, can't fire from inside a pocket, if you don't have a firm grip it may jam. has a safety that probably isn't needed since it is double action only.
It really comes down to 99.99 % reliability of those 5 shots or somewhat less reliability and more shots.. . . .
