If you\u2019ve ever considered upgrading your Glock, you\u2019ve likely considered adding an optic. But the idea of sending your slide off for milling might feel daunting, especially if it\u2019s your first time.\u00a0<\/p>\n
That was my perspective\u2014until I explored C&H Precision\u2019s slide milling service<\/a>. Known for their commitment to quality and precision, C&H offers a streamlined, customer-focused process that takes the guesswork out of custom milling.<\/p>\n In this review, I\u2019ll walk you through my experience sending in a Glock 17 Gen 3 slide for C&H\u2019s milling service and review their innovative Duty Optic<\/a>\u2014a closed-emitter design that enhances accuracy, even for users with astigmatism.\u00a0<\/p>\n This review covers everything from the order process and shipping to installation and performance, so whether you\u2019re on the fence about milling or just curious about the Duty Optic, read on to find out if it\u2019s worth the upgrade.<\/p>\n When you opt for C&H Precision\u2019s slide milling service, you\u2019re in for a well-organized process combining customer service and attention to detail. Here\u2019s how it went when I sent in my Glock 17 Gen 3 slide for milling to fit the Duty Optic:<\/p>\n The first step involves disassembling your slide, which means removing the sights and all internal components. Since C&H requires a stripped slide for milling, you\u2019ll need to take on this task yourself. However, if disassembly isn\u2019t your forte, C&H offers a disassembly service for an additional cost, making it accessible to all skill levels.<\/p>\n After completing the order, C&H sends you a specific address to ship your slide. The packaging is secure, and C&H provides clear instructions on how to prepare your slide for safe shipment. They prioritize streamlined communication at every step, which adds to the overall ease of use.<\/p>\n Once C&H receives your slide, a technician from their milling department contacts you to verify your order. This personalized call ensures that all details are correct and that they understand any specific requests. Knowing they double-check the service order provides peace of mind, as you can rest assured that your slide will be handled exactly as requested.<\/p>\n The standard turnaround time for the milling service is about two weeks, though they offer an expedited option for an additional fee. This flexibility is ideal if you need your slide back quickly for training or carry.<\/p>\n Once the milling is complete, C&H Precision<\/a> securely packages your slide and ships it back with a required signature for delivery. This additional step ensures that your custom-milled slide arrives safely.<\/p>\n C&H takes its service a step further by offering to mount any purchased optics directly onto the slide after milling. This includes adding witness marks on the mounting screws\u2014a thoughtful detail that helps ensure a secure fit. With the milling completed, I received my slide, installed the internal components, and was ready to test its performance on the range.<\/p>\n After having my slide milled by C&H Precision, I opted to have them install their Duty Optic\u2014a closed-emitter design built to withstand the rigors of Duty use.\u00a0<\/p>\n Known for producing high-quality optics, C&H\u2019s Duty Optic did not disappoint in terms of build, clarity, and ease of use. Here\u2019s what stood out about the Duty Optic and why it\u2019s a solid choice for those looking to elevate their pistol\u2019s performance:<\/p>\n Constructed with a rugged one-piece CNC-machined aluminum body, the Duty Optic is designed for resilience. It\u2019s waterproof (IPX7 rated for submersion up to one meter for 30 minutes) and 100% shockproof, capable of handling the heavy recoil of +P and +P+ ammunition<\/a>.\u00a0<\/p>\n C&H\u2019s attention to durability makes it a reliable choice for law enforcement duty use, daily carry, and range\/training use. For those concerned about environmental elements\u2014like dust, dirt, and water\u2014the closed-emitter design keeps the red dot protected and functioning clearly under all those conditions.<\/p>\n The Duty Optic offers ten brightness levels, with the lowest two settings compatible with night vision, catering to various lighting scenarios. The motion-sensing technology activates the optic with a simple shake (or holster draw), conserving power with an auto-off feature after five minutes of inactivity.\u00a0<\/p>\n Powered by a CR2032 battery, the optic boasts an impressive 50,000-hour battery life, meaning it can be used for extended periods without battery changes.<\/p>\n For anyone with astigmatism, finding a red dot that appears clear and sharp can be a challenge. The Duty Optic\u2019s 3 MOA dot\u2014available in red and green\u2014offers one of the crispest displays I\u2019ve encountered. I\u2019d even venture to say better than my Holosun 507c. Even with a slight astigmatism, the dot is clean and clear, providing excellent accuracy and minimizing eye strain.<\/p>\n This level of clarity makes the Duty Optic ideal for both close-quarters and longer-distance engagements. It lets you acquire targets quickly and maintain a precise hold at various ranges. I was able to consistently ring an 11\u201d steel plate at 50 yards with the Duty Optic. With tactile adjustments for windage and elevation, the Duty Optic can be easily zeroed, adding to its overall versatility.<\/p>\n Once my Glock 17<\/a> slide was returned, complete with the C&H Precision Duty Optic mounted, it was time to put it through its paces. After a straightforward zeroing process, I was eager to see how well the optic held up under range conditions and regular use. Here\u2019s how it performed:<\/p>\n Setting up the Duty Optic was seamless. The windage and elevation adjustments feature a distinct, tactile click with each 1 MOA increment, making it easy to fine-tune for pinpoint accuracy. After a few minor adjustments, I had the optic zeroed with minimal effort.\u00a0<\/p>\n This precise adjustability is a huge plus, especially when switching between different distances or ammunition types, allowing for quick and accurate recalibrations if necessary.<\/p>\n With the Duty Optic zeroed, I ran through an initial 100 rounds to test its ability to hold zero. From rapid-fire drills to controlled, longer-range shots, the optic stayed locked in place without recalibration.\u00a0<\/p>\n Even with the recoil generated by +P ammunition, the optic maintained zero with no shifting or drifting\u2014testament to C&H Precision\u2019s secure mounting and rugged design.<\/p>\n The closed-emitter design kept the red dot perfectly visible throughout my session, free from dust or environmental interference. The clarity and size of the 3 MOA dot made target acquisition almost instantaneous, allowing for faster transitions between targets.\u00a0<\/p>\n Whether at close range or farther out, the optic helped me maintain a precise hold with less time required for sight alignment, enhancing both speed and accuracy.<\/p>\n As for longevity, this was just the beginning of testing, but the initial 100 rounds left a positive impression.<\/p>\n I will be running several thousand rounds through this setup in the coming months to assess the optic\u2019s long-term durability and reliability under sustained use.\u00a0<\/p>\n However, based on this initial experience, the Duty Optic lives up to its reputation as a high-performance, robust choice for tactical and range applications.<\/p>\nThe C&H Precision Slide Milling Process: Step-by-Step<\/h2>\n
