Thunder Mountain Custom 1911 Slide Stop – 9mm | Stainless Steel | Serrated
Upgrade your 9mm 1911 with the Thunder Mountain Custom Serrated Slide Stop, engineered for shooters who demand precision, strength, and consistent performance. Unlike cast or metal-injection-molded alternatives, TMC CNC-machines every slide stop from a solid billet of stainless steel. Therefore, each part delivers tighter tolerances, superior durability, and dependable operation under hard use.
Precision CNC Machining for Superior Performance
Because Thunder Mountain Custom machines each slide stop from solid billet stock, the result is exceptional structural integrity and long-term reliability. Consequently, the slide stop resists cracking, bending, and premature wear, even during high round counts or aggressive training sessions.
Moreover, tight machining tolerances ensure proper engagement with the slide and frame, which promotes reliable lock-back and smooth function. As a result, shooters experience consistent performance whether on the range, in competition, or during defensive training.
Serrated Paddle for Positive and Confident Control
The serrated paddle design enhances traction, allowing the shooter to positively engage or release the slide stop with confidence. Therefore, reloads feel more controlled, and slide manipulation remains consistent even with gloves, sweaty hands, or adverse conditions.
At the same time, the serrations balance grip and comfort. Consequently, the paddle remains easy to use without feeling aggressive or uncomfortable during extended shooting sessions.
Optimized for 9mm 1911 Pistols
This slide stop features a precision pin diameter of .200 – 2.005 inches, ensuring proper engagement in 9mm 1911 platforms. However, because individual pistols vary by manufacturer and tolerance stack, minor fitting may be required. When properly fitted, the slide stop delivers smooth cycling, reliable lock-back, and repeatable performance.
Heavy-Duty Stainless Steel Construction
Stainless steel construction provides excellent strength and corrosion resistance, making this slide stop ideal for pistols exposed to sweat, humidity, or frequent handling. As a result, the finish holds up over time while maintaining reliable function and clean engagement surfaces.
Backed by a Lifetime Guarantee
Thunder Mountain Custom stands behind every slide stop with a lifetime guarantee. Therefore, shooters can invest with confidence, knowing this component is built to perform for the life of the pistol.
