Rock Island Armory Tactical Sights Dimensions

182844 Views 94 Replies 54 Participants Last post by  Peter RIA1911A1-MS
I have a Rock Island Armory Tactical and I would like to have a adjustable rear sight installed. Does this pistol have a Novak cut? It looks like a standard dovetail to me but I could be wrong. I know the pistol has Novak sights but I wasnt sure if it was a Novak cut on the slide. I need to know what type of sight to order. Thanks

Welcome to the forum JR!!! The RIA Tactical uses a Novak style sight, notice I said style so the cut in the slide might not be the exact size for a true Novak sight. Check with www.championgunsights.com
Nobody knows what style cut this pistol has?
It has a Novak style cut!!!
Thanks Auto Mag. I sent Champion Gun Sights an email last week but havent gotten a reply yet. I thought it looked like a Novak cut but I wanted to be sure before I order a new sight. Thanks

After some extensive research on here and elsewhere I found this info on this forum.

Hope that helps

Also, dawsonprecision is the only place ifound to carry/make sights for our "cut". The only downside is they only make fronts not rears. Armscor/RIA will do the work for $80 not including the price of the sights, you have to buy the sights then send all to RIA.

I have the .45acp tactical fs as well and trying the same thing, but not enough cash yet.
Good luck
Here are the specs for true Novak Sight cuts.

Right numbers, wrong places!
RIA Tac. front sight cut .330''x65% x.085''+-.002''-.003'' deep.
RIA Tac. rear sight cut .488''x.65 x.125''?? deep?

I had the factory diagram, but lost them, all of this is from memory...:scratch:
The true Novak Rear cut 495 X.65%
'' '' " Front Cuts, .330''x .65%x 70"- 75'' deep depending on the sight you choose?

the front sight is the problem, if you use the Novak front there will be a Air gap between the slide and the sight base of .015'' to .017''....:rock:

Thanks Andy, I always used the sticky from the other 1911 forum, now its gone???... the post is still there, but the Diagram is gone ...:confused:
Oh, well, at least we have our own copy now.
As often as this seems to come up...maybe this can become a sticky post here???
I have posted this as a new thread "Rock Island specifications" but I don't know how to make it a sticky. Help please?

I think only a mod can make stickies. Maybe send a pm?

If you know how to contact the moderator staff, let me know. I can't find a damn thing about how to request the creation of a sticky thread!
Send a PM to "Staff"

He is listed as a mod.

Well, Kids; this old bird is stumped! We cannot send PM's to the Staff or the moderator or anyone else in the administration of this pop-stand. Because of that I am afraid that my effort to start a permanent place for Rock Island specifications as a reference is a bust. I have one more round in my magazine and I'm going to fire it now...
Nobody ever checks the Staff e-mail. Please PM an admin if you don't get the results you seek.
