Are the SIGLITE Night Sights and the Trijicon night sights pretty much the same in quality and design?  

SIGARMS is having a "spring cleaning" Custom Shop special going on until May 15.  I've had my SIG P229 .40 for about 3 years now, and I've never broken it down or had it cleaned more than the usual field stripping.  So this Custom Shop special is just what my P229 needs.  

I was thinking of having them put in the SIGLITEs so I'm wondering if it's pretty much the same specs as Trijicon's.

Factory Siglites are made by Trijicon.  The front sight on my P239 has Trijicon on the top.

Thanks very much Aggie1.

what do night sights cost for a 220

Trijicons should be around $85-95 a set + shipping at wholesale cost. This assumes they are for the later 220's that are made with the dovetailed front sight. Older guns with front sights made as part of the slide (and there are lots of these around) must have the sight drilled with a carbide bit (very hard steel here!) and the capsule epoxied in place...which can be done by the Trijicon folks if you send them your slide (highly recommended for this since if they mess up, THEY are responsible) or, you can contact Sig and for a very reasonable price they will machine off the old sight, cut a new dovetail to spec and install their SigLite sights for you.

One thing to think about...
The SIGlites are made by Trijicon, but differ in that the rings around the tritium capsules are thin and silver-colored, making them a bit difficult to see when shooting in daylight.  The Trijicon aftermarket sights are similar, but the rings are painted white, making it easier to see in the daytime.  The white paint may flake off over time.  Meprolight nightsights have the white outline within the capsule, hence the rings won't wear off over time.

Personally, I have mostly SIGlites and Trijicons on my SIGs, but have installed Mepros on a couple of other handguns, and like them better.

The main difference between Trijicon's SIG sights and the ones they make for SIG, is the SIG factory Trijicons actually have the indented rear face on the rear sight light factory sights.  The Trijicon aftermarkets have a flat sight picture.

Trijicons are far and above Meprolites.  Meps have a nasty tendancy to have tritium modules work out of the sight.  I have seen this numerous times at the two departments I have worked at.

My Siglights are still crisp after 12 years.
