Are Rock Island 1911 forged or cast?

Can anyone tell me what process does Armscor use for making their 1911s? On their web site it says the frames are investment cast and the slides are forged, but I have read on different web sites that the gun is all investment castings.

Thank you

This is taken right from the www.rockislandarmory.com web site!! I hope this helps LAPD!!

Question: What are your frames and slides made out of?

Answer: Our 1911 Frames are Cast 4140 Carbon Steel and our Slides are Forged 4140 Steel.

Thanks for the links. I had the same question on a Citadel which I assume is the essentially same pistol.

Thank you about the info on the RIA 1911

Thank you gentlemen about the info on the RIA 1911.

Now some will argue that no "decent" gunmaker would ever use a cast-steel frame hence the Rocks are thereby "inferior" to their more costly cousins. Guess that makes Ruger and a whole lot of other famous names just a bunch of junk!
Truth be told whether cast or forged the raw frame is nothing more than a barely recognizable shape. It is the machining, fitting and finishing processes that follow that make the thing work. The frame of a 1911 is just that: a frame. It is the foundation that all the other parts use as a base for their actions. It should be stable and hold the other parts in proper position and assure that their paths are properly controlled. The elemental questions are: (1.) does it fulfill that purpose? and (2.) can it do so for a long time? As long as those two questions are answered in the affirmative it doesn't matter if the frame was cast, forged or whittled out of a block of steel with a laser (which I would personally like to see!).

Ruger's guns were all engineered with investment casting in mind, so you'd expect them to be good, cast guns. When the gun was never intended to be cast, then there might be a question about adapting the design to the process.

Caspians are also cast (by Ruger, if memory serves), and are as highly regarded as 1911 components come.

Springfield armory, norinco and Colt are the only having a forged frame and slide in there 1911's. I have no problem owning an investment casted 4140 frame 1911 too. My new Auto-Ordnance Army WW2 copy with its 4140 investment casted frame has over 500rds thru it now with no looseness or frame rail wear yet. I lube all my guns with moly. I'm looking at the new RIA 1911a1 in its nickel finish next.

Not all caspian frames are cast. They have a cast and forged line. Both are great to work with. If I'm not mikstaken the only downside if you won't to call it that is that supposedly you can't get as fine of a polish on the cast ones.

Caspian USED to have the barstock available. None for quite a while now.
