When you’re looking at a used Colt Mustang Plus II Mark IV Series 80 in .380 ACP, you’re not just buying a pistol; you’re picking up a piece of Colt history known for its solid build and compact footprint. This isn’t a polymer frame wonder; it’s a steel-framed, single-action pistol that feels substantial in the hand, especially for its size. The Series 80 firing pin safety system is a familiar feature for anyone who’s handled a 1911, offering that extra layer of security without complicating the trigger pull. For a concealed carry option, the .380 ACP chambering strikes a balance between manageable recoil and effective self-defense capability. It’s a pistol that has seen some use, as you’d expect from a used firearm, but it’s been inspected and is ready for its next owner. We’ve seen plenty of these come through the shop over the years, and they hold up well.

What are the Key Features of the Colt Mustang Plus II Mark IV Series 80?
This particular Colt Mustang Plus II Mark IV Series 80 offers a few standout features that make it a compelling choice. First, it’s a true single-action pistol, meaning you get a clean, consistent trigger pull every time, which many shooters prefer for accuracy. The Mark IV Series 80 designation indicates the inclusion of the firing pin safety, a mechanical safeguard that prevents the firing pin from moving forward unless the trigger is fully pulled. This adds a layer of safety without compromising the trigger feel too much. The Plus II model, specifically, has a slightly extended grip compared to the original Mustang, allowing for a more secure two-finger hold, which is a real benefit for recoil management in a small .380 ACP. The all-steel construction, while adding a bit of weight, contributes to durability and helps absorb recoil, making it more pleasant to shoot than some lighter, polymer-framed alternatives. It’s a classic design that has stood the test of time for a reason.
Who is the Colt Mustang Plus II Mark IV Series 80 for?
This pistol is well-suited for individuals seeking a compact, reliable .380 ACP for concealed carry. Its all-steel construction provides a solid feel and helps manage recoil, making it a good option for those who might find lighter polymer frames too snappy. Shooters who appreciate the single-action trigger and the classic aesthetics of a Colt will find this appealing. It’s also a good fit for someone looking for a backup gun or a pistol for discrete carry where minimal printing is crucial. Given its used status, it’s also a more accessible entry point for those wanting a Colt without the new-in-box price tag.
