My P938 Equinox front sight tube fell out. They are the true glow sights. I have some tube around but can't seem to locate it. I was in a gun shop in West Palm this morning and happened to remember, so I asked if they had any tube. The counter guy said no but asked what sight I wanted it for. I told him and he said you cant replace the tube because the glow wont transfer through it, you have to replace the front sight as a unit. I never heard this, is it true or just a nice thought?

It's true (per TruGlo - I never tried it), but if you contact TruGlo, they will probably send you a new set. I had some TFO's on a 229 a long time ago, and when my front sight rod popped out, they told me I couldn't just glue in a new rod because the glue would hamper the tritium light coming through. They offered to send me a new set.

The new TFX sights they make are more robust. Maybe you can talk them into sending you one of those.

I got a inch of the green plastic from my local gun shop. Still working after a year.
