The Bond Arms Z-Slayer is a stainless steel over/under derringer chambered for both .45 LC and .410 GA. At 0.9 lbs and 5.5 inches overall with a 3.5-inch barrel, it is one of the most compact two-shot options available in these calibers.

Features 

 
The frame and barrels are stainless steel throughout, which handles corrosion well for a carry piece. The rebounding hammer automatically resets after firing, a safety design that reduces accidental discharge risk. A cross-bolt safety adds a second layer of protection during transport. The automatic spent casing extractor pushes empties out when you open the action — useful given that you only get two rounds and need to reload quickly. The Z-Slayer is compatible with standard Bond Arms interchangeable barrels, so you can swap calibers without buying a new frame. 
 

Usage 

 
The .45 LC / .410 combination gives you the option of a single large-bore pistol cartridge or a short-range .410 shotshell load — useful where short engagement distances are likely. Two-shot capacity is a real constraint; this is a backup gun or a last-resort carry option, not a primary defensive platform. The 22 oz weight is moderate for a derringer of this size.

Discussion on the Bond Arms Z-Slayer centers on what a derringer is and is not good for, with the green finish generating its own commentary.

The aesthetics draw consistent attention. The green stainless finish is unusual, and owners who bought for that reason are generally satisfied with the visual result and the build quality — Bond Arms derringers are considered well-made in the derringer category.

The dual-caliber capability is a practical positive. The ability to run .45 LC or .410 shotshells gives flexibility, and the barrel swap system (compatible with other Bond Arms barrels) extends that further.

The two-round capacity is the most discussed limitation. Owners who understand they are buying a backup gun or novelty carry piece are fine with it. Those comparing it to compact semi-autos on capacity find it difficult to justify.

Recoil in the larger calibers is notable in a sub-one-pound frame — this comes up in most reviews and is a practical consideration for anyone who shoots it extensively.

Price is frequently flagged as high relative to what you get in terms of round count and practical defensive capability. The counterargument from satisfied owners is that build quality and the Bond Arms brand reputation justify the premium.
