zzulu Posted December 7, 2013 Share Posted December 7, 2013 I guess the subject line says it all. I would prefer a 0,145" to 0.150" wide notch instead of the 0.125". Has anyone defiled (sorry) a Dawson adjustable rear in such a way? I have never looked closely enough at one so I don't know if it is even possible to open it that much. It's curious to me at least that a wider notch is not offered for the "old eyes" etc. Link to comment Share on other sites More sharing options...

zzulu Posted December 7, 2013 Author Share Posted December 7, 2013 That's good to know. I have not asked the good folks at DP yet but now I am wondering if they will do the filing for me. Maybe I can get a 0.150" notch after all. ZZ Link to comment Share on other sites More sharing options...
Southpaw Posted December 7, 2013 Share Posted December 7, 2013 I wouldn't trust myself to do a good enough job by hand . If you're not set on the adjustable sights, their new Competition fixed rear sight is available in various width notches up to .155". I like the .135" on my G34.

bountyhunter Posted December 7, 2013 Share Posted December 7, 2013 (edited) In my day, I have filed more sights than I could count. More often, I am narrowing the front blade because of gun maker's love affair with .140" - .150" front sights that look like barn doors. Shaving the front sight makes the rear notch look bigger, also makes it easier to center IMHO. I have very good files for the purpose, and I also use kapton tape to protect the surfaces the file should not touch. If you are filing a rear notch, put a slight angle on the vertical edges to make sure the side you see presents a sharp edge. If you are filing a front sight, again a slight angle inward along the bore axis on each edge makes sure the side you see will look sharp.

zzulu Posted December 17, 2013 Author Share Posted December 17, 2013 (edited) I received my new DP adjustable rear and after seeing how thick the notch sides are (front to back) and upon further reflection, I decided not to attempt the modification. I coupled it with a DP .285x .100 FO front and after 100 rounds, I'm warming up to the .125 notch. (I have been using the stock Glock notch up until now) I plan to use this sight for a while and will re-evaluate it in the future. This process of selecting the best sight combination for me is a bit like finding the "best" carry holster. I have one that I love but I also have a drawer full of 'em! Thanks to all for the very fine input. ZZ Edited December 17, 2013 by zzulu Link to comment Share on other sites More sharing options...
ekratman Posted May 4, 2015 Share Posted May 4, 2015 Not to hijack the tread, but it seems resolved. Has anyone had trouble with a G34 fitting in the production box with these adjustable sights? I would like to give them a try, but don't want to find out after getting them they don't qualify. Link to comment Share on other sites More sharing options...
9x45 Posted May 5, 2015 Share Posted May 5, 2015 (edited) I filed my rears to .180" Seems too wide, but the results show they work well. You either have to use a Pilar file, only cuts on the sides, not on the bottom, and check right/left with a caliper to make sure it is an even cut. I have down a couple of sights on the mill, but it takes alot longer to indicate center, and cut, and the measured results with a file are within .002", without the setup.

b1gcountry Posted May 5, 2015 Share Posted May 5, 2015 What do you use to re-blue the metal after you cut them? Link to comment Share on other sites More sharing options...
Bugs Bunny Posted May 6, 2015 Share Posted May 6, 2015 Brownell's Oxopho-Blue (Cold Blue) works very well. Even better if you heat the sight up to just 100 degrees but really should use 4-0 steel wool very lightly and Re-blue the sight(s) several times.
