This review of the Rock Island Armory Tac Ultra MS 10mm 1911 highlights initial reliability issues, specifically failures to eject and extract, occurring within the first three magazines. The presenter discusses potential causes including magazine feeding problems, the need for more lubrication, and the possibility of a faulty ejector. Solutions explored include using different ammunition (ball ammo), upgrading to Wilson Combat magazines, and installing an EGW mag catch to improve feed ramp alignment. The presenter emphasizes the need for a reliable 10mm for backcountry defense against predators like bears, noting the pistol's all-steel construction contributes to manageable recoil, even less snappy than a 9mm.

Frequently Asked Questions

What were the primary reliability issues encountered with the Rock Island Tac Ultra MS 10mm 1911?

During initial testing, the Rock Island Tac Ultra MS 10mm 1911 experienced failures to eject and extract within the first three magazines. These malfunctions involved rounds getting stuck in the ejection port, indicating potential issues with the extractor or magazine feeding.

What modifications were made to address feeding problems with the 10mm 1911?

To resolve feeding issues, the presenter installed an EGW (Evolution Gun Works) mag catch. This part is designed to lift the magazine slightly higher, which improves the angle of the round feeding into the chamber and onto the feed ramp, preventing hang-ups.

How does the recoil of the Rock Island Tac Ultra MS 10mm compare to other calibers?

Surprisingly, the presenter found the recoil of the 10mm Rock Island Tac Ultra MS to be less 'snappy' than that of a 9mm pistol. This is attributed to the firearm's all-steel construction and the added weight from a mounted light, which contribute to better balance and recoil management.

What is the intended use for the Rock Island Tac Ultra MS 10mm 1911?

The presenter plans to carry the Rock Island Tac Ultra MS 10mm 1911 for self-defense against predators, particularly bears, during bow hunting trips. This is when a heavier rifle is not being carried, making a reliable sidearm crucial.
