I'm pretty sure the Ruger LCP is a licenced copy of, or a rebadged Kel-Tec P3AT. One of the characteristics of the P3AT you may want to check for in your LCP is that after firing a round, if you do not fully release the trigger before pulling it again, the hammer will drop from it's half cocked position without igniting the primer and you will have to pull the slide back far enough to return the hammer to the half cocked position before it will fire.I tend to believe like some, if what you are carrying now is too big, you aren't gaining much by considering the .45/.410.
My favorites for concealed carry
Glock 36 - single stack 45acp compact
Glock 29 - 10 rounds of 10mm all in a nice little package
and I just acquired one of the new Ruger .380 I'll admit I'm not big on .380acp, but I wanted something really small to carry for those days I didn't feel like lugging a bigger gun or something I could slip in my pocket real easy while on the Busa. So far so good, shoots great and hasn't had any malfunctions yet.
I've spent much time shooting Glocks (I notice you seem to like them.) and 1911s and they've spoiled me with short trigger resets. With them, I only have to release the trigger far enough to feel/hear a small "click" before pulling the trigger for the next shot. The Kel-Tec P3AT (and I suspect the Ruger LCP, though I haven't handled one yet) has a small "click" in it's trigger reset, but starting to repull the trigger at that point results in the above mentioned situation, and a "dead" gun until the slide is pulled. It is not a problem as long as you are aware of it.
