Hi Eric and welcome back. I have both a Girsan 1911 and several Rock Island Armory (including 9mm's and 10mm's) and the Rock Island is the superior pistol in build quality, fit. finish and accuracy hands down. Cheers, stay safe and enjoy!

Rock Island for sure. 💯‼️

Good evening to you!! The Rock Island Armory pistol is far better in build, fit and finish. Hope this helps. Have a good rest of your day.

Hi Eric, the choice between the Girsan MC1911 Untouchable and the Armscor Rock Ultra FS depends on your preferences. The Rock Ultra FS offers a higher capacity and slightly better weight distribution, making it a solid choice for those who prioritize magazine capacity. The Girsan MC1911 Untouchable, while having a lower capacity, may appeal to those who prefer a classic 1911 design with customizable features.
Stay safe & have a great day!
