I tried this thumb safety on 2 different frames and the shield would catch on the plunger tube so you couldn't even move the safety. The plunger detent assembly wasn't even installed at the time. Very poorly made. I talked to Brownells tech support and they told me that they have heard of this happening to other customers who purchased this thumb safety. So I am returning it and going with the EGW thumb safety which is better quality. Very disappointed with this purchase.

I should have read the reviews on this safety. The body of the safety is too thin so the plunger rides on its outside edge. I'm surprised it didn't pop out on mine but there is a youtube video that documents it happening to someone else. Ed Brown makes awesome parts but this is not one of them. Save yourself the money and time fitting this and go with the "other" brand on this part.

My first attempt at installing an extended thumb safety in my Colt Delta Elite was a failure as I had purchased a Wilson and the stud was too big to fit the hole in the frame. The Ed Brown stud fit perfectly. As noted on YouTube examples, filing of the safety is required. Removing the grips and the grip safety help in viewing your progress. Reinstalling the mainspring housing prior to filing so the hammer is functional is necessary also. Comparing the new safety with the OEM safety as you file helps considerably, especially when your down to that last file or two when the safety finally clears the sear. Took about an hour of careful filing. Even when the safety finally seats, check to make sure the safety will move through its entire range. I had to file a little more after it seated so that the safety would extend fully into the slide cut. Check all functioning parameters before live firing. A 5 star product except for the fitting. Buy this one before the Wilson.

After fitting a Wilson Combat safety onto a 1911, this one is a breeze. Very smoothly machined out of the box and only very minimal fitting to make it work like a charm replacing an ambi safety on a S&W 1911.

Looks great, feels smooth. Will definitely stock a few of these for future jobs.

As expected with any Ed Brown part, it is excellent. Fitting was required and this part is not a drop in part. There is enough material for this to be fitted to any milspec 1911. The safety is perfect for a ccw but has enough grip for target or competition. I have installed this safety on everything from colt's to the taurus 1911.

This was a nice addition to my old Series 70 Govt Model that I've been slowly tweaking for 29 years. Does require hand fitting, I used my original as a guide and took my time. Looks like it came on the gun new.

bought for a PT 1911 Taurus to replace the ambi-safety. It went in with minimal touch-up. I had to notch the engagement area just a bit to clear the sear, but only about 10 minutes worth of file-and-fit. I shaped up the area around the plunger tube as well to get a positive "click" engagement that I liked, but it really wasn't necessary on my gun. One thing worth noting is that the contact area for your thumb is much thinner than the picture led me to believe. Not a big deal for me, but I was a bit surprised when I received it in the mail.

These are great for carry or using in a milt sparks iwb holster, I also use them in my compition pistols. They are a great addition when you do a trigger job with a new sear. Worth every penny

Very good looking, fit, had to fit to sear, and had to lengthen grip safety to block trigger, all as expected. Has been in use for over a year still tight. I will buy again.

I have installed a lot of thumb safeties over the years and Browns are the best. No casting marks, high quality steel, and heat treated! They last forever just need proper installation, which I think JLAU missed.

Finish on the Ed Brown thumb safeties coming thru our shop have all been top notch. Nice polish, no casting marks or pitts. Plenty of material so it can be installed on any 1911! I've ALWAYs had good experiences with Ed Brown parts.

Does require gunsmith installation!

I installed this on my Springfield EMP. I fitted it to my pistol and everything went in fine, however, the thumb safety is so thin that the safety lock plunger pops out when the thumb safety is in "safe".

This thumb safety needs a wider wall to hold the safey lock plunger in. When it pops out, I am not able to move it out of the "safe" position. Not a very reliable part for a concealed carry piece.

Excellent replacement option for stock safety. Low profile prevents snags, but extended pad aids in release. Requires experience in fitting safety in order to fit correctly with positive engagement.

I have been using Browns Ambi and single sided tactical safety for over 10 years on most all custom builds. This is the best quality and shape for concealed carry guns with both Wilson style and Brown safeties. The steel ears hold tight and do not work loose like others I have used that require constant retightening. For competition guns look at Browns wide extended safety, you will not be disappointed.

Surface not polished properly.
Uneven polish.

Thought a high end part would be just that, high end. This is just your run of the mill safety.

Used on Kimber Ultra II, great look by being straight and parallel to plunger tube when disengaged. Size and ergonomics perfect for medium hand. Positive Engagement. Fitting required, plenty of material to work with.
For safety's sake please do not attempt unless
you know what you are doing.

unlike many of the low ball ambi safeties this one has a little leg that fits behind the grip panel to ensure that the safety doesnt fall apart... its the SAFETY!!! buy good parts!

This is the only safety that I will use on custom builds.

Used to replace ambi safety on my colt. Narrow profile helps with concealment.

This is NOT a drop in piece! Required metal removal to fit in a Taurus PT 1911. Would probably require fitting in all 1911-style pistols. Well built, looks great!
