What customers like
Reliability & Performance68%
This gun shoots no matter what it has going on - dirty guts, crap ammo, hurt feelings - it just will not jam.
Accuracy & Shooting45%
After trying six different brands of ammo and finding the right brand. At 50 yards I was pleasantly pleased with the brand of choice. 3/8" groups.
Ergonomics & Comfort38%
Compact, excellent feel and upon inspection looks to be a very engineered pistol.
Value for Money32%
Great gun at a great price. Love the sights has a very good trigger one of my edc never jammed hits what I aim it at enjoy shooting it.
Build Quality & Finish28%
The fit and finish is great, just what you would expect from Browning.
Common concerns
Feeding & Jamming Issues12%
Rounds don't even come close to feeding - ANY ammo. Big time nose dive with the mag.
Grip & Ergonomic Problems8%
I have to adjust my grip so my hand doesn't ride the slide release.
Trigger Pull Concerns6%
Trigger pull is a little stiff, hopefully more shooting will help settle it in.
Quality Control & Finish Issues4%
Really disappointed to find out the receiver is a painted alloy metal which already has a small scratch coming out of the box.
Frequently Asked Questions
1911 Colt Pistol Ammo
What kind of ammo does a 1911 use?
Most 1911s fire .45 ACP, though some modern variants chamber 9mm or 10mm. Standard .45 ACP ammunition ranges from 185 to 230 grain bullets.
Is a 1911 a 9mm or 45?
The original 1911 fires .45 ACP, which remains the most common chambering. However, modern variants are also made in 9mm. The 9mm offers higher magazine capacity and cheaper ammunition, while .45 ACP delivers larger bullet diameter. Both are widely available today.
Is 45 and 45 ACP the same?
Yes. .45 ACP and .45 Auto are the same cartridge. ACP stands for Automatic Colt Pistol. Both names appear on ammunition boxes and firearm specifications and are fully interchangeable.
Which is better, 115gr 9mm vs 124gr?
115gr loads are lighter, faster, and cheaper for practice. 124gr develops more momentum and energy, offering better barrier penetration and more energy transfer, with a softer push recoil compared to 115gr. For budget range work, choose 115gr. For defensive carry, 124gr hollow points offer a meaningful performance advantage.
