Quarter Circle 10 – the company resulting from a cowgirl in Texas with a deadeye, steady trigger finger, and an attitude the size of state itself.

Let’s take a look at what’s currently available and then what’s new for this specialist in the Pistol Caliber Carbine business…

What’s Currently Available

QC10 currently produces PCCs in 9mm, .40 S&W, .45ACP, and most recently 10mm (as of December, 2017).

This year for SHOT Show, they’ve added the QC5, an AR9 that takes MP5 magazines.

They’ve also teamed up with Gibbz Arms (creators of popular side-charging uppers) to create a fun and unique side-charging PCC.

In December, 2017, the QC10 team launched a 10mm PCC available in both 10.5″ pistol length and 16″ carbine. 7.5″ is rumored to be in development.

QC10 Works with f-1 firearms

Most recently, QC10 teamed up with the folks from F-1 Firearms to produce a hybrid PCC between the two companies. F-1 provides the uppers while QC10 provides the lowers, bolts, etc.

Last, but certainly not least – QC10 is creating a PCC that accepts Sig P226 magazines.

Now you can buy the PCC that uses the magazine that you already own, rather than having to buy a whole new magazine when you purchase the new firearm.

The new PCC from Quarter Circle 10 uses Sig Sauer P226 magazines.

About the Owner

In fact, Quarter Circle 10 owner Bettina Mathis used to compete in women’s shooting tournaments…until she consistently won over all other women. Then they made her compete in men’s shooting tournaments…until she consistently won over all the men as well.

A modern day Annie Oakley! The story behind the creation of the woman-owned company is just as interesting as the firearms it produces. But that’s another article for another day.
