Obviously the answer to your question is qualified by how you want to carry. Concealed, inside belt, etc. The LCP being of small profile is designed for concealed carry so I'll assume that's the direction you're going. Talon Training Group custom manfuactures a holster that is the best on the market IMO. It is an inside the pocket style holster. Link is below. http://www.shop.talontraininggroup.com/Wallet-Holster-Ruger-LCP-Brown-With-Laser-FL30RHBR3WL.htm I'd also recommend you check out this blog dedicated to the LCP. Great knowledge base for any question as yours re: the LCP. http://www.elsiepeaforum.com/forum/index.php Search your same holster question there and there you'll find some great opinions. There is also a video there that displays exactly why the TTG holste is the best IMP. You can draw with your index finger extended safely where others you cannot.
New, a basic model runs between about $250 and about #325 depending on where you buy it. Used, they usually go for about $200 in good condition.
It's like any non-plus P rated pistol. Can you do it? Yes. Should you do it? That's your choice. The LCP is NOT rated for +P and there have been instances of barrel burst incidents. Yet, there are also plenty of people who haven't had issues. Personally, I would stay away.
