How well does it hold up at -65 degrees? (In extreme slow motion.)

The test subject?

Remington R1 1911, also conditioned to -65°F for 2 hours prior

The video:

It was part of this test:

In the interest of helping those who live in Arctic and Subarctic climates choose climate-appropriate lubricant for their self-defense and hunting firearms, we temperature conditioned a Remington R1 1911 down to -65°F while lubricated with one of four popular firearm lubricants. The Remington R1 (save being a ‘series 80’ configuration 1911) was chosen because of its dimensional similarities to the widely-available 1911 handgun. Low temperatures tend to cause oil to thicken and lose some of its lubricating properties. The temperature point of -65°F was chosen as it represents the reasonable worst-case scenario for the coldest locations on earth and is the low temperature specified in NATO STANAG 4090 (Edition 2).
Ammunition performance also changes drastically in the face of extreme cold. Depending on the primer and the nitroglycerine content of the propellant used, chamber pressures can either drop or spike dangerously above SAAMI pressure limits. We went with the SIG Sauer 45 Auto V-Crown 200gr JHP load (E45AP1) after pressure testing many different manufacturers ammunition at -65°F on SAAMI conformal pressure equipment and finding that the SIG load offered the lowest pressure drop among the cartridges tested. In order to establish our baseline, the test firearm was cleaned in an ultrasonic cleaner for 30 minutes and then heavily lubricated with the lubricant to be tested. The firearm was then shot with a fully-loaded magazine (7 cartridges) until the last shot was fired. This sequence of events was captured on slow motion video using a Phantom 711 high speed video camera. Read more
