I'm a lefty who loves the 1911, but is 0-2 on ambi safetys so far. First was a Colt branded one that failed and the second was on a factory new Taurus 1911 (got it in a good trade, but it's gone now...).

I will be putting it on a Colt 1991A1 that is mostly a range gun. I might carry it on occasion, thus the need for the ambi safety. It won't see a lot of use and abuse, but I need to feel 100% confident in it.

Based on my internet research, my short list is:

Wilson bulletproof

EGW

Kimber

Price is not an issue and I can do the fitting myself.

Setting brand aside, there are at least two type of ambidextrous thumb safeties.

I have both, no issues with either.

1. most commonly seen is the set/type with the wing on the right side safety.  The wing rotates under the right side grip panel, so that panel has to be relieved to allow that wing to move back and forth.  The wing is what keeps the right side safety in place.

2. the other one has a longer sear pin with a notch just short of the right end of the pin.  It extends through the frame a small amount.  The right side safety has a small bevel on the front that fits into that notch in the pin and travels up/down/around in the notch as the safety is moved from safe to fire.  That bevel on the front of the right side safety fitting/moving in the sear pin notch is what keeps the right side safety in place.

Both work fine for me.

And I have not idea, now, what brands any of mine are.  I've installed several over the last 35 years or so.  Only had to "fit" one.  That last one had to have a little metal removed to allow it to move between fire and safe.

Good luck.

Radian Talon because it uses a detente instead of a screw.  I think right to bear has them on sale for $38 right now.

Or I would buy the EGW or a Wilson bulletproof. I wouldn’t use a Kimber ambi.

EGW or Wilson Bulletproof.

I've used Wilson and I like the shape. It's blued and iirc the egw is parkerized and I would go with that one depending on the finish.

EGW

Thanks,

The EGW is advertised as "blued", but looks like a matte finish. I'm probably going to have the pistol re-parked, so I guess the finish does not matter in the long run.

Take a look at the LWRC ambi selector

Wilson bulletproof

I installed a Wilson Bulletproof Ambi on my Colt CCU and have been very happy with it. Fitting it was very easy and it has a very tactical feeling up and down click. All the edges are very dehorned too and it feels great.

Umm, wrong thread, maybe?

It's a shame King's is out of business now. They made the best, IMHO

I have used both of these with good results. I'd go with whichever of these 2 matches the finish of your gun or simply whichever profile you prefer. I like the Wilson on a carry gun and EGW on a competion gun.

both EGW and Wilson sell a King copy, Kimber may as well.

I've always used Ed brown large wide flat.
