Hank (Tarheel), excellent post. I too am a little concerned about some of the recent tutorials that I have read, albeit I have to say, they are extremely informative, enlightening at times, and well-written. And if I can speak for all the moderators at Elsie, I think we have some of the most knowledgeable and willing-to-share members (did I say well-behaved too?) of any online gun forum. Having said.....(you knew it was coming ), keep in mind that the LCP is a mass-produced weapon and while it may lack some of the refinements found in other guns costing hundreds more, has a stellar out-of-the-box record for reliability and simplicity. There is very little that needs to be done to this gun that will provide a significant improvement - know and accept its limitations, appreciate its strengths.
Nevertheless, the occasional problem will occur that cannot be addressed with the simple mods we've suggested (fluff and buff, feed ramp and chamber polishing, proper lubrication and cleaning, etc all discussed here and elsewhere in the forum). In those cases, it is best to send your gun back to Ruger for a look (and a fix). You are dealing with a company with perhaps the best customer service in the industry and that should provide a degree of comfort.
When considering a home "make it better project" a couple of thoughts to keep in mind.....
1. Do you have the requisite skills to perform the job? (In my case, my tool kit at home consists of a butter knife and the Yellow Pages. If i can't fix it with the butter knife, I grab the Yellow Pages.) In short, know your limitations.
2. Do you have the proper tools to perform the work?
3. Are the benefits to be derived worth the expenditure of time and potential risk to your gun, your safety, and your warranty?
4. Have others with a comparable skill level performed the work successfully and did they experience a significant improvement in functionality?
5. Simple parts like guide rods can be replaced at no charge (I am told) - Ruger will keep you in guide rods forever if necessary should the part need to be replaced. Frames, barrels, and slides are a different story.
The LCP is a relatively simple design point and shoot pocket .380, but IMHO, it's the best $300 point and shoot pocket .380 available on the market today at that price point. It has an excellent reputation, kudos to you for choosing wisely. Don't go overboard in an attempt to improve. There is the danger of going one step forward and two steps back.
