The Thumb Safety -1911 shooters know how important it is to get this one part right. Every draw stroke, press check, shot fired, reholster...involves interacting with the thumb safety.

Done wrong, the thumb safety can be a constant source of irritation. Sharp edges, lousy action and poor fit to the shooter can make running a 1911 a chore.

Done right however, say by a high end custom 1911 builder, the thumb safety helps the pistol become a natural extension of the shooter. It should fit well under the thumb, be devoid of any sharp edges, and offer a positive action with every flick on and off. Shooting and handling the pistol now becomes an effortless joy.

That is what we've captured in the Chen Thumb Safety. Right out of the box, without having to have a gunsmith 'rework' a safety until it works, feels, and looks right. We believe the Chen Thumb Safety is perhaps the most 'finished' thumb safety on the market today.


Ergonomically Sculpted Lever. Follows the natural curves of the thumb for ultimate shooter comfort.

Fully Dehorned. Every edge is carefully broken or radiused for shooter comfort.

Clean, Flowing Lines. Lines you would expect from a high end custom pistol, after the pistolsmith has spent a considerable amount of time shaping, blending and sculpting the part.

Positive Engagement. Crisp and clean engagement. Detent geometry was tuned and modified so that the safety positively snaps either on or off. There is no muddy, wishy-washy feel, nor any "bounce" at the bottom of the stroke.

Integrated Design Designed in conjunction with the Chen Beavertail Grip Safety. The two parts meld together when fitted together properly.

Precision Machined. Meticulously Manufactured IN-HOUSE. Incredibly tight tolerances throughout. The shaft is perfectly concentric and held to max tolerance to aid in more precise function and fit with the grip safety. It is also dead nuts parallel with the safety paddle, also enhancing fit and function.

These parts are made on high-end, extremely rigid and accurate Japanese machinery capable of mold-making precision. Multi-axis machining techniques allow for extreme dimensional consistency, leading to more precise fitting to the pistol.

These are made under my personal watchful eye. No dickering with vendors, no accepting something that’s “good enough” because you don’t want to hassle with sending back a batch that wasn’t quite right. Here, it either meets my extremely high standards or it goes in the scrap bin. Period.

Two lengths available. More on the way.

This is not a drop-in part. While the Chen thumb safety was designed to be as finished as possible, it does require fitting of the safety to the sear for installation.

Reviewer: Greg Butler from Milford, KS United States  
I recently fitted the stainless thumb safety on one of my 1911s. It is well made and feels amazing. The great craftsmanship is obvious as soon as you open the package! The M&Ms are good too!

5 of 5 New go-to thumb safety April 12, 2020
Reviewer: Zack Hagler from Midland, NC United States  
Have the mid length versions is stainless and blued and they are excellent.  Zero clean up work to do on them like removing machine marks etc.  Greg Derr described them as having lines like an Italian sports car and I think that's spot on.  These will be my go-to thumb safeties.

5 of 5 The best thumb safety around! April 12, 2020
Reviewer: Chuc Nguyen from West Farmington, OH United States  
My 1911 came with a decent thumb safety but it was lacking in cosmetics and ergonomics.  The lever was pointed slightly above the frame rail and slightly too rectangular in shape.  I knew that it was the first to go or get shaped and blended.  Then I saw on Instagram Stan Chen’s thumb safety...  The Chen thumb safety a work of art that blends function with aesthetics and ergonomics!  To that end, the thumb safety perfectly matches up with the Stan Chen grip safety.
