First Impressions of Advantage Arms Glock 20/21/20SF/21SF .22 LR Conversion Kit w/ One 10-Round Magazine and Range Bag
The Advantage Arms Glock 20/21/20SF/21SF .22 LR Conversion Kit w/ One 10-Round Magazine and Range Bag promises a cost-effective and enjoyable way to train and plink with Glock’s large-frame pistols. This kit allows you to convert your Glock 20, 21, 20SF, or 21SF to .22 Long Rifle, offering cheaper ammunition and reduced recoil for extended range sessions. It seemed like the perfect solution to maintain my proficiency with my Glock 21 without breaking the bank on .45 ACP ammo.
Having recently committed to more frequent range visits, the rising cost of .45 ACP ammunition was becoming a significant deterrent. I needed a more economical way to maintain my muscle memory and practice fundamentals with my Glock 21SF. The promise of converting it to .22 LR for training piqued my interest immediately.
Unboxing the kit, I was immediately impressed by the fit and finish of the Advantage Arms slide. The black anodized finish looked durable, and the slide felt solid. The included 10-round magazine felt well-constructed, and the range bag was a welcome addition.
I considered a dedicated .22 LR pistol like the Walther P22 or the Glock 44, but the conversion kit’s ability to maintain the familiar Glock grip angle and trigger pull was a deciding factor. Ultimately, I wanted to train with a setup that closely mirrored my carry pistol. The Advantage Arms kit appeared to offer a better training experience than purchasing a new .22LR handgun.
My first impression was one of cautious optimism. The kit looked promising, but I was eager to see how it performed on the range and whether it lived up to its accuracy claims. I was hoping for a seamless conversion and reliable functionality.
Real-World Testing: Putting Advantage Arms Glock 20/21/20SF/21SF .22 LR Conversion Kit w/ One 10-Round Magazine and Range Bag to the Test
First Use Experience
I first tested the Advantage Arms conversion kit at my local outdoor shooting range on a sunny afternoon. The conversion process was surprisingly straightforward; after ensuring my Glock 21SF was unloaded, I simply removed the factory slide and replaced it with the Advantage Arms .22 LR slide. Within minutes, my Glock was ready to fire .22 LR.
The kit performed reliably for the first few magazines. I used CCI Mini-Mags, a high-velocity .22 LR round known for its reliability in semi-automatic pistols. The accuracy was acceptable, grouping within 2 inches at 15 yards.
However, after about 50 rounds, I started experiencing failures to eject (FTEs). I was surprised and a little dissapointed. The issues increased as the gun got dirtier.
Extended Use & Reliability
After several weeks of use, the Advantage Arms conversion kit’s initial promise faded somewhat. While it remains a useful tool for low-cost training, reliability issues persist. Regular cleaning is absolutely crucial.
The anodized finish has held up well, with no visible signs of wear despite hundreds of rounds fired. The magazine also remains in good condition. The ease of cleaning is a plus.
Compared to my previous experience with a dedicated .22 LR pistol, the Advantage Arms kit requires more frequent cleaning and is more prone to malfunctions. While it replicates the Glock’s ergonomics, the reliability is not on par with a dedicated .22 pistol. Overall, I found it slightly dissapointing in terms of reliability and cleanliness.
Breaking Down the Features of Advantage Arms Glock 20/21/20SF/21SF .22 LR Conversion Kit w/ One 10-Round Magazine and Range Bag
Specifications
The Advantage Arms Glock 20/21/20SF/21SF .22 LR Conversion Kit w/ One 10-Round Magazine and Range Bag is designed to convert Glock’s large-frame pistols to .22 Long Rifle. It is compatible with Glock 20, Glock 21, Glock 20SF, and Glock 21SF models. The kit includes a complete .22 LR slide assembly, one 10-round magazine, and a range bag.
The caliber is .22 Long Rifle, providing a significant reduction in ammunition cost compared to .45 ACP or 10mm. The magazine capacity is 10 rounds, which is standard for most .22 LR pistol magazines. The manufacturer is Advantage Arms, a company known for producing conversion kits and aftermarket parts.
The included magazine means less reloading at the range. Having a dedicated .22LR slide allows for quick caliber changes, optimizing the firearm for training purposes. Being able to train with .22LR, allows for more time to focus on shooting fundamentals.
Performance & Functionality
The Advantage Arms Glock 20/21/20SF/21SF .22 LR Conversion Kit w/ One 10-Round Magazine and Range Bag performs adequately as a training tool, but it is not without its quirks. The accuracy is acceptable for close-range training, but not competition-grade. Reliability can be inconsistent, especially with lower-quality ammunition.
Its primary strength is its ability to replicate the Glock’s ergonomics and trigger feel, which is valuable for maintaining proficiency with the original platform. A significant weakness is its sensitivity to dirt and ammunition type, leading to malfunctions. It doesn’t exceed my expectations for overall performance.
Design & Ergonomics
The build quality of the Advantage Arms slide is generally good, with a durable anodized finish. The slide assembly is relatively lightweight, which contributes to reduced recoil. The ergonomics closely mirror the Glock’s original design.
The kit is reasonably user-friendly, requiring no specialized tools for installation. There is a slight learning curve in terms of finding the optimal ammunition and cleaning schedule to minimize malfunctions. I had some difficulties with the reliability of the product due to the complex nature of .22LR ammo.
Durability & Maintenance
The Advantage Arms conversion kit appears to be reasonably durable, with no major signs of wear after several months of use. Frequent cleaning is essential to maintain reliable function. The kit is relatively easy to disassemble for cleaning and lubrication.
Proper maintenance is vital to ensure the kit functions optimally. I would recommend keeping the slide assembly and magazine clean and well-lubricated. It is better to clean after every trip to the range.
Accessories and Customization Options
The Advantage Arms Glock 20/21/20SF/21SF .22 LR Conversion Kit w/ One 10-Round Magazine and Range Bag comes with one 10-round magazine and a basic range bag. There are limited customization options directly related to the kit itself. However, you can use aftermarket Glock sights on the Advantage Arms slide.
Aftermarket Glock sights allow for some customization of the kit. Some shooters have reported success with aftermarket magazines designed for similar .22 LR conversion kits. I have not been able to successfully add any customizations to the unit.
