Max It Posted October 15, 2014 Share Posted October 15, 2014 hi ya, my xd9-Tactical came with Trijicon night sights, which I promptly took off in favor of competition fibre optics. now my buddy bought a XD9 and I am thinking he could use these. however they are blank! no light left. it was sold new to me in May of 2009. do you think I have a chance to get them to replace the sights from Springfield? Or am I missing something? Link to comment Share on other sites More sharing options...
GreenDragon64 Posted October 15, 2014 Share Posted October 15, 2014 They should last longer than 5 years. No luminescence whatsoever? Link to comment Share on other sites More sharing options...
Max It Posted October 16, 2014 Author Share Posted October 16, 2014 yup, some luminescence. I needed them at night in a dark space. I don't know if they were stronger when new. but I guess this is good. I have no way of measuring light, do you? Link to comment Share on other sites More sharing options...
RIIID Posted October 16, 2014 Share Posted October 16, 2014 The vials can be damaged in the removal/install process if done incorrectly. Is there a date on the rear sight where their name is? Rich Link to comment Share on other sites More sharing options...

KSwift Posted October 16, 2014 Share Posted October 16, 2014 Sounds like they're exactly as bright as they're expected to be, you're just unimpressed with how they dim. 5 year old night sights are not easily visible in a lit room, if you can see them in a bathroom or closet at night with no lights on and no light from under the door, then Trijicon won't be any help, they'll offer to replace the vials for a price.

hceuterpe Posted October 17, 2014 Share Posted October 17, 2014 (edited) Tritium has a half-life of a little over 12 years. The sites should be marked with a year of manufacture. What is that? If you damaged them so they leaked, I would say it likely wouldn't illuminate at all, since the gas is much lighter than air. So if they illuminate at all, its likely just aging Edited October 17, 2014 by hceuterpe Link to comment Share on other sites More sharing options...
Max It Posted October 17, 2014 Author Share Posted October 17, 2014 its clearly marked '08' which make sense since the gun was mfg in 2008, I bought it new in 5/09 and the sights were professionally taken off in favor of the competition sights I had put on. (in those days I hired people to do my gunsmithing, since then I do it ). and Swift got it right I expected brighter, but they are probably fine. Today I checked the trigger pull and it is 3 1/2#; too light the way it is for a night stand gun. so if I need another one of those I will look elsewhere in my collection. I will save this thread should I get the urge again, I can always change the pull. Link to comment Share on other sites More sharing options...
JASracer Posted October 29, 2014 Share Posted October 29, 2014 They should last longer than that, although it sounds like they still work. I had a set installed on a Beretta 96 in 2000 or 2001. The still work to this day. They seem a little more dim than when they were new, but I can see them in a dimly lit room. Link to comment Share on other sites More sharing options...
