I was at roughly my 270th round fired through the pistol and I got hit in the eyepro by what I thought was a casing but then noticed my front sight had disappeared. I never messed with it or even noticed that it was loose so …this was a surprise. I’ve already contacted PSA and they have sent out a “replacement part” …so assuming they send me just the front sight how would I go about installing it? I don’t start work again for a few weeks and won’t be able to afford to take it to a gunsmith for a while as I get caught up financially and I don’t want to retire the dagger because in 300 rounds I’ve had only one failure to eject/fire ( which happened in the first 80 rounds) and this sight issue ,so any help would be greatly appreciated.

It only fits in the hole one way. If you don’t have a front sight tool you’ll likely have to grind a taper on a socket to tighten it up. Use lok-tite.

Use blue locktight, not red.

torque?
5-7 in/lbs. Blue loctite.
5-7inch pounds? I don’t think I can measure lower than 10 inch pounds
I found the easiest way for precision torquing of the front sight is the simplest.
First, obtain an inexpensive Glock front sight tool.
Second, attach a one-inch lever perpendicular to the axis, sufficiently far-enough away from the working-end to not interfere with the slide. Really, anywhere works.
Next, tie a length of 10#-test fishing line (for the double safety-factor) to the end of the lever.
Chuck your slide horizontally, with the fastener-hole perpendicular to the floor in a bench vise, at 5 to 7 foot-pounds.
Install the new sight and fastener, then attach your precision-modified Glock front-sight-installation tool to the fastener.
From the 10#-test fishing line, you will hang a certified, calibrated, 5 to 7 pound weight for exactly one minute (no more, no less).
This is the procedure Gaston Glock himself detailed in the original Glock Armorer’s Manual and Microwave Cookbook in 1979.
“But how will I know my vise is holding my slide assembly at the requisite 5 to 7 foot-pounds!” you say?
So glad you asked.
First, obtain a vise with a 1-foot-long tensioning-lever…

so basically,if I’m reading you right, 10 inch pounds is within tolerances and I should just send it…

Precision is Absolutely Paramount. Didn’t you read my Tutorial?
I kind of got lost at microwave cookbook…

Yeeeeaaahhh… just loctite it and snug it up.

as a home mechanic for the last 25 years, I’ve seen that very same advice lead to more than one repeat failue. :)) and I’m sure PSA would appreciate that I don’t continue losing these little pieces on the business end of the firing line…so I think I’ll go snug and a 1/16 turn…for honor. If you get on her stay on her…

I had repeated issues of the front sight coming loose on my Dagger FS-S. I was using Blue Loctite 242. I eventually switched to Blue Loctite 243 which is for higher temperatures. I have a red dot on this weapon, but I still check the front sight for looseness every time I shoot. It has been a common problem on Daggers.

I just noticed while wiping down the slide after reassembly that the front sight is loose again. Did I not yell at it properly last time?
are ya sure you read the directions on the loctite properly! 
after 24 years in a garage I refuse to let some snork with a labcoat tell me how to properly lubricate a fastener with an adhesive! That being said I applied a small amount to the threads and tightened until my 5 dollar tool no longer was able to stay on the fastener. oh well, I’ll resnug it later when I’m not coughing up amorphous blobs .
