    LCI filler
    Good looking product but unfortunately Ruger didn't do me any favors with the 22/45 Lite. The "inner" barrel was twisted ever so slightly so I had to use a dremel to cut the pin holding the orginal LCI in. I then found the TK replacement would not fit because of a slight lip from the inner barrel. I used a dremel to sand down the TK replacement and now it looks great. Good product but know that if you are putting in into a 22/45 Lite you may need to modify it.

    I have no problem with the concept of a loaded chamber indicator, but I did experience some failure to feeds from mine getting dirty and sticky. A cleaning would fix it, but during a single range visit it would get dirty enough to start sticking. That is why I recommend this part! The LCI insert looks great and the black finish is a near perfect match.

    Worthwhile mod
    This is a good mod which simplifies cleaning a bit and eliminates one of the unnecessary features dreamed up by the lawyers. A refrigerator magnet wouldn't extract the LCI pin so I used the "telescoping magnet parts picker upper" I had (about $3 from Harbor Freight) which did the trick. This part fits perfectly. I used a bit of blue loctite on the set screw (probably not necessary). The finish doesn't match my blued barrel that well, but it probably blends in nicely with a matte barrel. The original LCI is actually less noticeable, since the color is closer to that of the barrel. Not a big deal unless you're obsessive about such things.

    LCI Replacement Insert
    Another high quality product from Tandemkross. Excellent fit and easy installation. Make shure you use a strong magnet to remove the existing LCI pin.

    Great mod to the Mark III 22/45
    Easy addition to add to the pistol. Watching some of the youtube videos using a magnet to get the pin out was just the trick. Very nice finely machined metal piece. Great innovation, much easier to keep gun clean.
