1911 Spur Hammer
This United Defense hammer is a replacement fire-control part for 1911-pattern pistols. The hammer is the part that swings forward under spring pressure to strike the firing pin. It suits owners replacing a worn or damaged hammer, builders assembling a 1911 from parts, and anyone who wants a traditional spur profile with a checkered thumb pad.
Features
- Classic Spur Profile — A long, curved spur extends rearward so your thumb has a clear surface to cock the hammer by hand.
- Checkered Thumb Pad — Raised diamond checkering on the tip of the spur gives a positive grip when cocking or lowering the hammer.
- Black Finish — An even matte black surface matches most blued or black-finished 1911 slides and frames.
- Hammer Pin Bore — The larger hole is the pivot point, where the hammer pin passes through and holds it in the frame.
- Strut Pin Hole — The smaller hole takes the pin that connects the hammer strut, the link between the hammer and the mainspring.
- Slotted Base — A cut through the lower body houses the hammer strut so it can move freely as the hammer cycles.
- Machined Sear Engagement Surfaces — Notched hooks at the base engage the sear, the part that holds the hammer cocked until the trigger releases it.
- Built For The 1911 Platform — Made to the 1911 hammer pattern for use in pistols built on that design.
Fit and Installation
The hammer comes as a single bare part, without pins, strut or springs. The 1911 has been made by many manufacturers over the years, and fire-control parts like the hammer and sear often need some fitting to work correctly together. If you are not experienced with 1911 trigger work, have a qualified gunsmith install it and check the sear engagement and safety function before you fire the pistol.

Great hammer, stupid good dealI grabbed this hammer on sale for my 1911 build and honestly, I wasn’t expecting much for twelve bucks. But man, this thing is solid. The finish matches my other parts perfectly, and the fit was dead-on no filing or fitting needed. The spur gives a nice positive grip, and the black oxide feels durable.
For the price, it’s a no-brainer if you need a reliable replacement or spare.

works goodFirst one dropped right into my 1911 build no issues so I ordered a second one to keep on the bench but the black oxide finish had a slightly lighter spot near the spur otherwise solid part.

No HassleOnce installed, the hammer gives a clean break and the hammer spring is just right for my 10‑round mag. I've put it through 800 rounds with no binding or wear. Definitely worth the cash for the reliability.

Great Upgrade For My 1911Dropped this hammer into my RIA tactical and what a difference. Trigger pull feels way cleaner and the reset is noticably crisper. Put about 300 rds through it last weekend with zero issues. Fit was tight but not so tight I needed to do any fitting with a file.
No fitting required on my RIA

Highly recommendSwapped this in my RIA 1911 and it's been flawless through about 500 rounds now. Crisp trigger reset and no issues whatsoever. This is a quality part at a fair price.
Smooth operation
