Hey want to try fitting a sight to my range officer as I did not like the adjustable sight.
Well I am having trouble. I have a few small hobby files and have been working with the triangle file for about 3 hours and this sight is not even close. Am I missing some thing? I have tried taking off most of the material from the rear wing of the sights dovetail. Also took a little off all the other surfaces that touch the slide. The sight has started to slightly fit, but VERY minor. Are Harrison design LPA sights just very oversized? |

Quoted:
I had to dress mine just a little bit with a stone, I'm talking just a little bit on one side of the dovetail to get it started. Other then that it tapped right in. <a href="http://s1117.photobucket.com/user/hummsale/media/1911.jpg.html" target="_blank">http://i1117.photobucket.com/albums/k581/hummsale/1911.jpg</a> Very nice gun |

You need to remove metal from the bottom of the sight, not the angled part. Grab a proper metal file from a hardware store, it will cut quickly. Check the fit frequently when cutting. Once you can push the sight in halfway with your fingers, your sight tool or a hammer/brass punch will
do the rest. Put a drop of oil on the sight to help it along. |

As our colleagues above have said, only remove material from the bottom of the sight base. I use a belt sander to start and, when the dovetail starts to enter the cut in the slide, I work it down the rest of the way with emery cloth on a flat surface (usually a stone).
When the sight will go in half way, I dress it a bit more and then drive it home with a brass drift punch. DO NOT REMOVE ANY MATERIAL FROM THE GUN AND DO NOT REMOVE ANY MATERIAL FROM THE SIDES OF THE SIGHT! |

If I don't remove material from the very front if this sight there is no way it will ever fit...
Either my 1911 is out of spec or the sight is. I tired just removing material fro. the bottom of the sight only. Sight wouldn't go in anymore. But more and more light would show through the bottom. So that's why I tried to remove material from the back portion if the dovetail. Sight fits better now but still the front end of the sight hits the cut in the slide. So how do you guys think i should proceed? |

Measure the old sight and new sight with a pair of calipers or a micrometer, both the thickness of the dovetail tang and the width front-to-back. You can figure out pretty quickly which dimension(s) need to be changed.
Filing only on the bottom of the sight will generally work OK when the sight is only very slightly oversized. If things are much further off, you may need to take material off the dovetail front or back. |

If I were you, I would just keep filing it until it fits. What other option is there? Match the dovetail on the sight to the dovetail on the slide, either by purchasing the proper sight or cutting the proper dovetail in the slide. Butcher shop gunsmithing is for dweebs. |

That is stupid. The sight is the consumable part, and the dovetail is obviously the way Springfield wanted it, or they wouldn't have been able to install the factory sight. If the dovetail they used is different, that doesn't make it improper. |
