OK, first exactly what Springfield did you buy you say "Tactical" so I'm assuming that it's an XD Tactical???

The two sizes are PROBABLY sight heights which will vary pending on bbl. length.

Can you post a link to the sites in question? I just looked at the Trijicon website and didn't see different sizes...

There was a site last night that gave be a option for two different sizes, and i believe u r right it was the height. When I went to order them tonight I could not find the site that listed two different sizes. So I did order them trijicon sights from cabela's. I was 2nd guessing myself and was just worried about ordering the wrong sights... I have a xd .45 tactical 5" barrel. Is this going to be a problem if the height is different from the stock sight I have?

Are you 100% positive that you were looking at Trijicon made sights? Trij's website doesn't show different heights.

I don't think it will be a problem as the original XD line is supposed to require a 6 o'clock hold, if the new sights are shorter, you'll probably end up with a Point of aim=point of impact sighting system, the the sights are taller however, you'll be shooting low. A link to where you saw the two different heights would be fantastic. If you can't find it, I think you'll be OK.

I know Meprolight has different sights pending on barrel length and caliber, is it possible you were looking at a different make/model?


Also, on the upper left of the screen is the avatar section, where it says "welcome Foldemtime" under there is where you can get to your inbox.
