I've got a 4.5" Trailside Standard Model (drift adjustable rear sight) with an UltraDot MatchDot on low rings, but I want to zero the iron sights.

I understand the Trailside Standard Model will accept Sig's standard drift-adjustable rear contrast sights, as follows:

No./Height/Sig Item No

#6/5.80mm or 0.23"/3422555_06
#7/6.07mm or 0.24"/3422555_07
#8/6.35mm or 0.25"/3422555_08
#9/6.62mm or 0.26"/3422555_09
#10/6.90mm or 0.27"/3422555_10

My first question is: Which sight height does the Trailside Standard Model ship with? The number is supposed to be stamped on the sight, but my Trailside doesn't have one.

If no one knows the answer to that question, how do I measure my sight to determine it's height? From the base to the bottom of the notch? Or from the base to the top of the sight?

I'd prefer to get my Trailside zeroed as well as I can with the right drift-adjustable rear sight. The irons are just "backup" for the MatchDot. If I can't do that, I'll probably the adjustable sight from Larry's Guns. Does anyone have the adjustable sight from Larry's guns on a 4.5" Standard Model? If so, how do you like it?

Thanks for your time and assistance.

If you haven't already, post this on sigforum.com. LOTS of trailside owners there.

I posted the question there and on www.rimfirecentral.com

I posted the following when I got the answer:

[QUOTE=Bruce in WV]that it was shipped with. I drove out the (cheapo plastic) rear sight, bought a cheap plastic caliper, and measured the overall height (.23in top to bottom) and notch (.125in from bottom of notch to bottom of sight). My guess is that the others follow the same pattern.

Thanks Bruce! - That's exactly the information I was looking for! :)

Sounds like they come with the plastic equivalent of Sig's #6. That means I can go up or down in 2" increments (at 25 yards) by going up or down a rear sight number.

P.S. Here's some info on the sights and adjustments: www.sigarms.com/documentation/Universal_Sight_Pusher_2002.pdf
