What sights?
 

What style sights do the RIA's take? The TAC Compact specifically.

I imagine John will have to answer this for you!

I have one, they should be Novak sights.

DrHenley, the older guns used a Novak "style" sight and cut but I have heard that the newer guns are using a true Novak cut and LPA sights.:)

New ones definitely use Novak dovetails. A few days ago, I swapped the rear of my FS TAC with a Novak LoMount.

The front dovetail, while somewhat undersized, is also a Novak cut.

After much digging and research and talking to RI when I bought my TAC II awhile back it turns out that they don't exactly use a Novak cut, it is similar but a bit smaller then Novak.

I have installed sights on two different RI 1911's on one I used a Novak cut sight and it worked but it was a lot of work to make it fit. On the second I used a RI sight form Dawson Precision and this one worked much better. Dawson cuts their sight's slightly smaller to allow you to fit them but it was pretty easy to fit.

Good to know thanks! I want to upgrade mine or I'm just going to get some paint and paint them on
