Description
The Nowlin Speed Demon II is built for one thing: getting you back on target faster. By cutting weight without sacrificing durability, this hammer reduces lock time so you can get off follow-up shots quicker than stock. That matters in competition where milliseconds count.
What Makes the Speed Demon II Different
Nowlin starts with solid tool steel bar stock and uses wire EDM cutting followed by CNC machining to dial in the geometry. The fully-cut hooks and pre-ground engagement surfaces arrive ready to work. You won't need to stone or adjust anything before dropping it in, which saves time and means the parts work together as intended from day one.
Built for Competition, Made in the USA
The stainless finish resists corrosion while the chamfered edges reduce stress points and help prevent cracking during heavy use. Heat treated to Rc 53-55 hardness, this hammer is engineered to last through tens of thousands of rounds without going out of spec. Nowlin stands behind it with a lifetime guarantee against breakage if left unmodified.
Installation and Compatibility
This 1911 hammer fits standard Series 70 and 80 frames and is designed to work with Nowlin's Ultra Low Mass or Match sears for the best results. The pivot pin hole is precisely dimensioned at .1565 inches for perfect alignment. While installation is straightforward for those familiar with 1911 takedown, a qualified gunsmith can handle it quickly if needed. Also available as part of the complete Speed Demon action kit if you want a full trigger job package.
