TMC 1911 Hammer Slot Stone – 800 Grit Precision Ceramic
Smooth Hammer and Sear Movement Starts Here
The TMC 1911 Hammer Slot Stone delivers precise control when smoothing critical contact areas inside the 1911 frame. This stone fits exactly between the frame tangs and around the hammer and sear pin areas, allowing you to remove friction where it matters most. As a result, your hammer and sear move freely, and your trigger pull feels noticeably smoother and cleaner.
Because trigger quality depends on smooth internal movement, this stone plays a key role in any serious 1911 trigger job.
Designed to Remove Hidden Friction Points
During frame manufacturing, the thumb safety hole and the hammer and sear pin holes are typically drilled last. Consequently, small ridges often form around these holes. These ridges increase friction and interfere with smooth hammer and sear movement.
By polishing these areas with the TMC 800 grit hammer slot stone, you eliminate those ridges quickly and safely. Therefore, you reduce drag, improve consistency, and create a cleaner trigger pull.
Precision Ground for Exact Fit and Control
This stone features a precision-ground square profile that fits perfectly inside the 1911 hammer slot. Because of its exact dimensions, it maintains flat, even contact with the frame surfaces. In turn, this allows controlled material removal without rounding edges or altering geometry.
Additionally, the 5-inch length gives you excellent leverage and control, making detailed work easier and more accurate.
Premium Ceramic for Fast Cutting and Smooth Finish
TMC manufactures this stone from premium white ceramic impregnated with aluminum oxide. This material cuts efficiently while still producing a very smooth surface. As a result, you achieve fast results without aggressive removal.
Moreover, the fine 800 grit finish creates the lowest possible friction in the hammer slot area. This directly contributes to a lighter, crisper trigger feel and more predictable reset.
Essential Tool for a Clean, Crisp Trigger
Whether you are refining a match trigger or tuning a duty pistol, this hammer slot stone helps you reach professional results. By smoothing internal contact surfaces, it supports consistent engagement, smooth cycling, and long-term reliability.
Simply put, no serious 1911 trigger job feels complete without addressing the hammer slot—and this stone makes that job precise and repeatable.

WHEN THE SIDES OF THE HAMMER, SEAR, & GRIP SAFETY MOVE BACK & FORTH INSIDE THE FRAME, BOTH THE FRAME & SIDES OF THE PARTS NEED TO BE VERY SMOOTH BECAUSE THEY MAKE FRICTIONAL CONTACT WITH THE FRAME. SMOOTHER MANUAL & SLIDE COCKING, EFFORT WILL BE A LOT EASIER, PARTS WILL ENGAGE WITH EACH OTHER WITH LESS EFFORT, & HAMMER FALL WILL BE A LOT QUICKER & THUS REDUCING THE IGNITION “LOCKTIME” !!!!! ANOTHER ESSENTIAL STONE FOR ONE’S BENCH-TOP—-OORAH & SEMPER-FI !!!!!!!
