Trijicon rear sight

[Laudanum]

Asked on another forum, no joy so trying here ...

I'm replacing sights on a combat commander. I've installed enough sights before but have a question specific to these (Trijicon brand). This is the rear for gov. dovetail. Normally, I would file to achieve a press fit 1/3 or maybe a hair more into the dovetail, then drift. But the Trijicon sight seems to be made out of a lighter/softer metal. I can get them just started into the dovetail and Im wondering if I should just try and drift them without filing at all, or fit as I usually do. If it weren't for the tritium vials I would probably just try the former without even seeking advice, but, would much rather not trash em

I would appreciate some input from anyone that has installed these Trijicon brand sights, specifically.

You can try.

If it becomes apparent it isn't going to go in?
Knock it back out and fit as usual.

I prefer to fit them so an excessive amount of pounding isn't necessary in order to take no chance of breaking a glass vial.

Then I use Blue Lock-Tight for final installation.

You've installed them so I will take your advice and will file/fit first. I'm almost tempted to drill and tap for a set screw just for some extra insurance. Then again, I'm not even 100% sure I want to install this sight. I staked in the tritium front but Im not all that big on needing/wanting a tritium rear. I may go with a plain black rear first and see how it shoots. I have a gov. Novak in the parts box. I think it may be a 2 dot though. Anyway, it may very well regulate with the front sight. Hmmm.

Thanks for the advice, it's very much appreciated.

IMHO a little drop of "wicking grade" Loc-Tite 290 on the dovetail after verifying the sight-in with a few shots is better than the Blue for this purpose.

Has also solved a lot of loose sight issues for me.

Agreed on the green, wicking type Loctite.

Just an update ... The material that the Trijicon rear in this sight set is made from is not very amenable to filing (nor taking cold blue). Not like a standard "iron" sight. Suffice it to say that I essentially just ended up drifting the rear in. I had to go after it but not to the point of whaling on it. It never had that "dead stop" feeling. Got it just about 2/3 of the way with a small delrin tipped aluminum punch and a delrin rod and finished it with a delrin capped steel punch. It survived just fine. It wont need any Loctite, it isn't going to budge from recoil.
