The Diamondback Sidekick is a DA/SA revolver chambered in .22 LR with a quick-swap cylinder for .22 WMR — no tools needed. The 3-inch barrel and birdshead grip keep the package compact, and the black Cerakote finish on the barrel and cylinder holds up well against corrosion. At 1.53 lbs and 9.88 inches overall, it handles easily.

Detailed Features 

The interchangeable cylinder is the main draw here — switch between .22 LR for cheap practice and .22 WMR when you want more punch, without buying a second gun. The standard trigger is smooth enough for accurate shooting, and the polymer birdshead grip gives a comfortable hold during extended range sessions. Cerakote keeps rust off the barrel and cylinder even in humid conditions. 
 

Target Audience 

This revolver works well for new shooters who want an approachable first handgun, and equally for experienced shooters who want an inexpensive practice or small-game gun. The light weight and mild recoil make it easy to run for hours at the range. 
 

Usage Scenarios 

For small game — squirrels, rabbits — the .22 caliber at close to moderate distances is effective without excessive noise or meat damage. At the range it's a low-cost plinker. The dual-cylinder capability means you can carry .22 WMR in the field and swap to .22 LR back at camp for casual shooting.

Users of the Diamondback Sidekick tend to land in a few consistent camps.

The dual-cylinder design draws the most enthusiasm. Being able to run .22 LR for target practice and swap to .22 WMR for field use is widely seen as the gun's defining advantage, particularly for shooters who want one revolver that covers both roles.

Price is a recurring positive — owners consistently describe it as good value compared to other revolvers in its class, especially for a dedicated plinking or small-game gun.

Build quality gets mixed marks. Some owners praise how solid it feels and how the Cerakote holds up; others have noted the lightweight construction feels a bit plasticky and raise longer-term durability questions. Whether that's a plus or minus depends on how much carry weight matters to the buyer.

The trigger and recoil are generally well-regarded. Most shooters find the pull smooth enough for accurate work, and the .22 recoil is low enough that extended sessions stay comfortable.

Accuracy at distance can be a weak point with some ammunition types, and there are occasional reports of cycling hiccups with specific brands. Most users recommend testing a few ammo types to find what the gun likes.

Customer service experiences vary — some owners report straightforward warranty handling, others describe slow response times.
