You must cycle the slide if another pull of the trigger is warranted in the event of a misfire, as with a Glock or similar system. In doing that, you'll eject the round in the chamber and insert a new one, which is probably a desirable outcome as the odds are rather overwhelming that a second hit on an apparent dud round is going to result in a discharge anyway.
Snappy
Armed with knowledge of the LCP's nuances, I gave it a good cleaning, packed up an assortment of ammo, and headed to the range. I had a mixture of previously cycled, nicked, and scarred ammo from my PPK/S, including some Remington FMJ and hollowpoints, Blazer FMJ, and Federal Hydra-Shok hollowpoints.
Aiming the LCP revealed that the sights blend into the slide pretty well. But that's OK considering that the pistol is intended for up-close defense. Regardless, my aging eyes always seem to benefit from a dab of white paint here and there so I went ahead and put a microdot of white on the front sight. That made a dramatic difference in the sight picture for me, anyway.
My goal on this first trip was more to check out function and reliability with accuracy evaluation being secondary.
