Well, I'm going to buck the trend here and say I agree with most of what you want to do, DP. It's a foregone conclusion that I'm going to get those sights on my LCP. I have the CT on mine which is pretty much what I need for low light, but the laser is worthless in the daylight. As far as point shooting I just don't feel comfortable doing that much past 4 or 5 yards, for me the hit ratio is unacceptable at 7 yards. So if I won't point shoot, and I can't see the laser, what options are open? Yep, those totally unseeable sights. If the target is more than 7 yards away I won't take a shot without seeing the front sight on target, which is hard to do when you can't see the sight. Do you see a pattern here? To me, in my opinion, the taller sights are a no-brainer, got to have them.
I agree with you about the LCP squirming around in the hand, I would love to see a new frame with a double stack mag with an 8 round capacity....ok, back to reality. I put a Houge grip on mine because it has a bit of a palm swell. I increased that by putting a couple pieces of double sticky tape on each side of the grip frame and on the back strap as well. The tape also helps the grip stay in place. With that and the pinky extension I can empty the mag without my grip changing any.
Here's a couple of freebies for you. When I got my LCP I was having problems inserting the mag, once it got started it was ok. So I broke out my handy little needle file and I beveled the bottom edge of the mag well, now I can pretend to be Todd Jarret! This next one is only worth it if you reload...I was noticing that the case mouth was getting flattened, and I could see a bit of brass on the ejection port where the case was whacking it so out came my needle file again. I was thinking about lowering the port a little, but I ended up just rounding the edge some. I still get a ding in the case but I don't have to use an expanding die to make it round before I resize it.
Anyway, there's my 2 cents worth, you probably over paid me for it....
