The Kimber Amethyst Ultra II is a subcompact 1911-pattern pistol chambered in .45 ACP with a 3-inch barrel and Single Action Only trigger. The Amethyst Purple PVD coating over a satin silver frame is a deliberate cosmetic choice. It stands out from the standard black or silver 1911 options. Tactical Wedge 3-dot tritium night sights and thin G-10 ball-milled grips in purple/black are standard.

Features 

The 3-inch barrel and 1.6 lb. weight make the Amethyst Ultra II genuinely compact and light for a .45 ACP platform. The aluminum match-grade trigger has an estimated pull around 4 to 5 lbs., consistent with Kimber's custom shop standards. Tritium night sights work in low-light without battery dependence. The thin G-10 grips keep the width down for concealability while providing a secure grip surface. 
 
The PVD finish on the slide provides corrosion resistance and scratch resistance beyond standard bluing or standard PVD. The satin silver frame finish on the aluminum frame contrasts with the purple slide. This is a collector-grade aesthetic on a carry-capable platform.

The Amethyst Ultra II draws attention both for its appearance and its .45 ACP chambering in a 3-inch barrel. The distinctive color scheme is a deliberate purchase decision for most buyers. Owners who chose it did so knowing exactly what they were buying, and they're satisfied with the execution.

On the shooting side, compact .45 ACP pistols generate real recoil, and the Amethyst Ultra II is no exception at 1.6 lbs. with a 3-inch barrel. Most owners consider this manageable with practice. Range performance reports are positive for accuracy, and the tritium night sights earn consistent praise for low-light use.

Pricing is the main point of friction in buyer discussions. Kimber commands a premium, and some buyers compare the cost against other .45 ACP compact options with higher capacities. The 7+1 capacity is the limiting factor noted most often. Subcompact .45 ACPs simply can't match higher-capacity 9mm options in round count. Whether that trade-off makes sense depends on the buyer's priorities.
