No, The RIA FS A2 Pistols Are Not 2011s – They Are Oversized 1911s

I posted about 9mm magazines for the Rock Island Armory (RIA) FS A2 pistols and a friend on FB, pointed out they weren’t 2011s. The difference being the 2011 has a modular grip assembly and the RIA pistols are just over-sized 1911s. It dawned on me that I really didn’t know the difference and needed to do some reading.

How “2011” originated

It turns out that Chris was right – there is a difference – a substantial difference.

From what I have read the original 2011 concept was essentially a modular 1911 receiver that could have the mag well / grip sub-frame swapped out to allow for more versatility. The 2011 design and patent was by Virgil Tripp and Sandy Strayer who together formed STI and then went separate ways and shared the patent,.

The design is really cool and the best way to help you learn more is to provide you a link to the original patent application that has written descriptions and drawing — click here to see the orginial patent.

Back to the Rock Islands

The RIA pistols are oversized 1911 pistols. The grip and mag well area are integral parts of the frame and can’t be separated plus they use thin grip panels.

At the top is my RIA 566459mm Pro Match. Below it is an 80% frame for that model. Note now the mag wel/grip area are all part of the receiver and that there are grip panels. It’s not modular in other words. This makes it an over-sized 1911 and not a 2011.

In Closing

So now I know a bit more about the differences between the 2011 and 1911 designs. The RIA pistols are oversized-1911 designs and not true to the original 2011 design concept.
