Jocko,
Please understand, I am not trying to knock the pistol, or quarrel with you.
You've posted on two different forums that your friend has put 2500 "flawless" rounds through his pistol & people are starting to quote you on it.
You provided me with his email address, for which I thank you. We've been emailing and I'm very interested to be following how his pistol is working out.
I appreciate you giving me a channel to communicate with somebody who's actually doing a relatively high-volume test with one of these Rugers.
Like mine, his will not feed certain loads, he says. Like mine, his damages case rims, he says. Unlike mine, his drops empties much closer than 20-40 feet. Unlike mine, his also doesn't display one other issue that I'm waiting to see resolved on the second test pistol I'll be trying out next week.
So far, we have two samples that display some behaviours in common, and others not in common. Either or neither may be representative of the model across the board.
The ammo sensitivity is no big deal. In a package this small there's simply less room for variations in OAL and bullet nose profiles than with larger pistols, and even larger pistols will work more reliably with some types of ammunition than with others. Find a load that works in your LCP & run with it, this doesn't condemn the gun. But, on the other hand, it's just not quite the perfect pistol you were portraying.
I don't consider the case rim destruction a huge problem in how it leaves the cases regarding reloading. The pistol wasn't built to be handloaded much & as you say, the greatest majority of shooters won't roll their own ammo. In that sense it's not a major issue. Likewise with how far the thing tosses empties. In the defensive niche it was designed for, finding the brass will be the problem of your local police forensics people should you ever have to use it in that context & not something you'll care much about. Anywhere else, clean up behind yourself if possible & move on.
But, in conjunction with other factors, both the ejection distance & rim tearing can be indicative of something else going on inside the pistol. Doesn't guarantee a problem, but they can be indicators.
All I'm trying to do here is state the facts a little more accurately than your post above did regarding your friend's LCP.
Your post was portraying it as something it isn't.
Like any other pistol, it has its own quirks & personality.
