Frequently Asked Questions

Is the Rock Island STK100 a good choice for first-time 1911 shooters?

Yes. The STK100 delivers all the core features that make the 1911 platform popular—good ergonomics, reliable trigger control, and straightforward operation—without excess cost. If you want to learn the platform or add a budget-friendly 9mm 1911 to your rotation, this is a solid entry point.

What magazine capacity does the STK100 come with?

The STK100 ships with a 17-round detachable magazine, which is higher capacity than a traditional single-stack 1911. This makes it practical for range sessions and defensive carry if you choose to carry it.

Is 9mm Luger ammunition easy to find?

Yes. 9mm Luger is one of the most widely manufactured and available pistol calibers in the US, making it economical for practice and easy to source when you need it.

Does the STK100 work for concealed carry?

The STK100 is built on a full-size 1911 frame. While some shooters do carry full-size guns, this model is better suited to open carry, range work, or home defense than to everyday concealed carry. If concealed carry is your goal, consider a compact or subcompact platform.
