FYI if anyone thinks their Ruger LCP-Custom would be more useful with better or more durable or night sight.
Ruger sold/sells a lot of a LCP .380 variation with a good (red) trigger and real sights called the LCP-Custom. This is not the original gun and not the LCP-II, both with fixed sights.
The Ruger white dot is too small and my sight screw literally broke off with the sight departing into limestone gravel. I looked around for better.
Glock steel front sights have a big dot and a strong screw. Except for the too long oval trunion sticking through a thinner slide top, Glock sights are a perfect fit in the Ruger's front sight oval.
Reduce the oval's insertion height and reduce the screw length after it is tightened. That combination has about 800 rounds fired that way and was quite satisfactory for a $10 steel Glock front sight. The flat at the top is on purpose in the design. Make sure you get the large flat top dot. The older smaller Glock front dots are round.
Perfect proportion. Exact 15 yard zero.
Photos: Two below with Glock sight installed. The Ruger factory rear has bright white nylon fingernail polish on the ears making them visible.
Pretty good idea, but still just a nice white front sight dot.
I kept looking for a better sight that fit or could be fitted.
For a real step up in usefulness and quick acquisition of the front sight,
Ameriglo's GL-212-OR-Q is likewise a perfect fit in the Ruger copy of a Glock front sight oval. Standardization?? The Ameriglo Glock sight is a large orange square with a night sight tritium lamp installed in it. In slow fire, you align it with the white ears of the factory rear Ruger sight. In rapid fire, put the orange square on the target and pull the trigger. In the dark, half a night sight set gets you aligned.
Photos: Four photos follow showing the orange square night sight installed under the slide and in view.
Under slide with Ameriglo oval trunion reduced in height so screw pulls up tight.
Fits sight flat neatly.
Sight picture in perfect proportion with white fingernail polished rear. Looks better in real arms length.
LCP-C with orange square installed.
Best of all is either combination presents a point of aim using top of front sight with a 15 yard point of impact.
Obviously, the Ameriglo sight is staying installed.
Both were Red Locktited to the slide's tops since I learned not to trust tiny screws. Optional idea. Messy to do, but semi permanent, screw or not.
