I still say the LCP. To me the whole point of a .380 is you can have a very light and small carry pistol. If you're gonna go with a gun as large/heavy as the SIG or Walther, why not go with a more powerfull 9mm the same size/weight like a Kahr PM9 or Kel-Tec PF-9? Nothing in .380 is lighter/smaller than the P-3AT and the LCP is very close behind. That Rohrbaugh weighs 5.2 oz more than the Kel-Tec. That's a pretty substantial difference in a daily pocket carry gun. Also there's no external safety to fiddle with or accidentally bump off on the LCP or P-3AT like there is on the Walther and SIG, just point and pull the trigger. Simpler is better for a carry gun IMO. If all you want is a .380 for the target range, then by all means get the larger, heavier SIG or Walther. For defense carry, I don't think any .380 can beat the Ruger or Kel-Tec. Just my opinion.
