"Honest, professional, knowledgeable assistance in a clean, well lit, smoke-free enviroment."
Many love the look, feel and reliability of the Glock. For many a Glock is the perfect handgun but for one missing item, a manual safety. Cominolli Custom has solved this problem with the Glock Manual Safety Kit (MSK). The MSK is a high quality, American designed and American made thumb safety kit that can easily be installed onto your Glock. The MSK will fit and function in any Glock, any generation and any caliber (except for the Glock 36). Though there is no substitute for safe firearm handling, the MSK helps prevent unintentional discharges. The manually engaged safety lever provides an extra level of security and safety for Glock owners. When engaged the safety lever blocks trigger movement, not allowing the trigger to be pulled and the handgun fired. The slide can still be cycled and the handgun loaded or unloaded with the safety engaged. This safety operates easily with your right-hand thumb with a positive on-off engagement (down is off, up is on). The safety contact pad is easy to engage, yet won’t interfere with holster fit. All Glock passive safeties continue to function normally and instillation does not affect the Glock factory warranty.
If you want the absolute best safety for your Glock, choose the MSK. If you want the absolute best MSK instillation choose Premier Arms. Why choose to send your Glock to Premier Arms for a MSK? Simple, I have installed hundreds of the Cominolli MSKs over the past 12 years. Premier Arms is the only recommended installer in the state of Indiana. Premier Arms is a Glock Stocking Dealer and has Glock Certified Armorers on staff. We recommend, sell, use, and install only the best quality, proven Glock accessories. I thoroughly researched the MSK before deciding to stock, sell, and install them. I installed the first MSK on my personal Glock. I looked at the tolerances and construction quality of the kit. I was impressed; the parts are precise in both fit and finish. After I installed the kit in my Glock, I functioned it dozens of times. Each time the safety worked as it should. When the safety was off, the Glock fired as it should with no change in function or trigger feel. When on, no matter how hard you pulled the trigger, the Glock would not fire. In fact, I wanted to see where the failure point on the safety was so I unloaded the Glock, engaged the safety and then pulled as hard as I could. The trigger actually broke, but the Glock never “fired” and the safety stayed engaged. The same Glock, unloaded, was repeatedly dropped onto a hard surface from 6 feet. The safety stayed engaged. Since then, over 11 years later, the same Glock has been used as a demo in the store. The safety has been activated and deactivated hundreds if not thousands of times. After all of this functioning, the MSK works the same as when it was new. This is a quality product, period.

Premier Arms will provide you with a professionally installed MSK on your Glock. The MSK instillation is a straight forward process and simply done, if you have the right equipment and skills.
We completely disassemble the frame, removing all of the internal parts. A notch is then cut in the left rear side of your Glocks frame. This is accomplished using a precision aluminum jig with a nylon guide. This produces an exact, precise, professional cut for the instillation. The cutting jig is precisely aligned on your frame using the pin holes. A high speed carbide cutter is used to cut a small notch in an exact position on the side of the frame. Once the frame is cleaned of all cutting debris, the MSK is installed. The Glock is reassembled and function checked.
When professionally installed by Premier Arms, the MSK looks like it came from the Glock factory. Once it passes final inspection, it is on its way back to you, the customer.
Premier Arms has the proper equipment, skills and experience to install the MSK on your Glock, trust the experts.
