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.

5 of 5 The right safety. October 7, 2021
Reviewer: Jeremy Jenkins from Louisville, KY United States  
Fit right after a light file message. My original thumb safety dug right into my thumb crease creating  a hot spot. Knee those smooth long edges would feel much nicer. Thx for the awesome product. Looking forward to one of your rear sights as well.

5 of 5 Chen custom thumb safety July 2, 2021
Reviewer: Shoji Kai from Houston, TX United States  
It came very securely packed with a detailed installation guide (proper printout, not degraded copies of copies). Packing slip had a hand written message thanking the purchase. It also came with a pack of M&Ms - very nice touch! The product is of very high quality, and although the installation required some fitting, it is easy with the aforementioned installation guide (it has a clear picture of thumb safety with a file at a correct angle for filing). Safety gets into on position easy, and to disengage, there is a very crisp click (no slack). I am now a very big fan of Stan Chen Customs!
