Adrian,
After patents on early Glock models expired, many manufacturers began producing clones, leading to a variety of quality levels. Some high-end clones even surpass Glocks in certain areas, such as better ergonomics, upgraded slides, optics compatibility, and premium materials. Notable premium options include the Shadow Systems MR920, known for its features and competitive price; the Zev Technologies OZ9, appreciated for its modular chassis and top-tier performance; and the Walther PDP, often considered superior in ergonomics and trigger feel.
For those prioritizing affordability and reliability, the PSA Dagger is highly regarded for its dependable performance and comfortable grip at around $300. The Ruger RXM offers good sights, Glock magazine compatibility, and is optics-ready. There are other clones worth mentioning, but I can only speak on these since I’ve personally tested each one.
Hope this helps, Adrian, and happy shopping!

Hi Adam and welcome. To be honest, superior is relative. Better, aesthetics, options and accessories seem to be across the board with the clones. As far as base function, reliability, they are not superior to Glocks, just more purdy. Cheers, stay safe and enjoy the Glock clone windfall!

Hello, The CZ P10C is a striker-fired, polymer-framed handgun designed as a competitor to the Glock 19, often referred to as a "Glock killer" due to its similar size and functionality. It is considered a Glock clone in terms of its compact size and overall design, being Glock 19-sized, and it shares compatibility with many Glock accessories, including holsters. However, it features distinct characteristics such as an aggressive grip texture, a partially cocked striker, and a modern frame design that differentiates it from its competitors. I personally own this and will definitely say it a great gun with a trigger that is crisp. Happy shooting!
