I have a 10-8 rear sight :
02-140 - .325" height
.140 wide notch
What front sight or what dimensions should I look for? Will the front sight on my Springfield MC Operator work?
Any help would be appreciated.

With my TRP I use a 10-8 rear and stock front. If your pistol shot point of aim-point of impact at a distance you were satisfied with you should be fine.
http://www.10-8performance.com/store...products_id=30The rear sights are available in heights to match your existing rear sight height, and will therefore be directly compatible with your existing front sight. You will want to measure your existing rear sight before ordering.
I looked at that already, and I already own the sights. So I have to do the more complicated route. Thanks for the link though.
On the 10-8 web page, it does not say their front sights match this or that rear. It says, "Have a gunsmith do it". I am having Gunsmith Nelson Ford do it, but I prefer to make it easier rather than harder on him. And I want the best result.
As long as the rear sight is the same height as the 10-8 rear the POI stays the same. No need to replace the front sight but if you do please let me know as I might be interested in buying it from you if it has the white ring around the tritium.
The easiest thing to do that would probably save you the most grief if you are planing on using the existing front sight on your MC Operator would be to get the extra tall .375 10-8 rear sight. This will regulate perfectly with the stock front sight.
I have been down the same road with the 10-8 rear sight. I first ordered the standard height rear sight for my Springfield Loaded and it didn't regulate at all. I tried 3 different front sights before finding the shortest (.160 ) height front sight from Novak that would work. Then I saw that Dave Berryhill had some 10-8 sights with a traditional square notch in them but only regular height. I called and spoke with Dave ( great guy by the way ) and his recomendation was that if I was running a Springfield to go with the extra tall rear sight as it would make life a lot easier. Of course being stupid enough not to take his advice I ordered the sight and continued to struggle with the correct sight set-up until I ordered the .375 height rear and went back to the stock front sight height which worked exactly as Hilton said it would on his website and Dave confirmed.
So when I received my MC Operator I ordered a .375 height 10-8 rear and walla, FM happened. I now run a .375 height 10-8 rear on my Springfield Loaded, I have a bag with 4 used 10-8 rear sights sitting on my bench and have sold my MC Operator.
In my opinion, the 10-8 rear is a great sight for many different reasons. I shot two USPSA Single Stack Nationals with them, used them exclusively for about 3 years both on and off duty and it is the rear sight that I currently use on my off duty gun ( a Glock 19 which is a whole other story unto itself.)
Hopefully my experience will save you some time and money and of course only applies to the Springfield 1911 models with Novak sight cut and 10-8 rears.
I hope you get the rear sight working how you want it to. Keep us updated on the solution that you and your gunsmith reach and how it turns out for you.
Good luck!
ColdDeadHands is correct. You need to look at the POI of your pistol.
In your case, the math is simple. Your pistol already has a Novak rear sight that is .325 high so where is the POI? If it shoots to your point of am then you can replace the Novak rear sight with a similar (10-8) rear sight that is .325 high and use the existing front sight (or replace the front with another sight that is the same height). There is a formula that you can use to calculate the correction needed.
If your point of impact is different than your point of aim then you'll need to adjust it with a rear and/or front sight having a different height.
I wasn't making a blanket statement about all Springfield Armory pistols. Some Springfield Armory 1911s come from the factory shooting low but if yours shoots to your point of aim and you install a rear sight that is .050 taller, such as the .375 high 10-8 sight, then you'll need to raise the front sight by about .050 to maintain your POI. Let's say your current front sight is .180 tall. You'd need to replace it with a front sight that is .230 high, which is a little tall for a practical pistol and not really necessary unless you need to raise the sights above a suppressor.
The reason that Hilton and others don't recommend a specific front sight height is because of the pistols that have stock sights (without a Novak rear sight). In that case it's difficult to estimate the correct sight height due to all the variables involved.

I have an old set up sights from my TRP you can have. Just PM me your address and I will drop them in the mail. I am tripping over old sights just going to waist. The best front sights that have the bold white ring are the ones that come from Ed Brown. I really like Ed's BOLD white lines. But I do have some old Springfield's that have good night sights, but weak white lines. Just PM me.
CDH, DB and Shawn C, thanks for the good info. From what I understand, my 10-8 is .325 and my current Springfield is .325 so it should work just fine by simply replacing my rear. POI is fine with current sights. Even though I am not crazy about that front sight, it will work.
So Dave, if I want to replace, I just order a front sight that is .325?
So the simple rule is: Front sight height should equal rear sight height correct? Pretty basic but you never freaking know the rules till you know the rules.
