    I'm going to install a Ed brown extra wide ambi saftey on my springfield 1911. any guidance from members would be great. I have practice on some older thumb safeties to get a better understanding of how this works. Any advice some one could offer would be great. Thanks

    assemble the gun minus the grip safety when youre fitting it, so you can see the sear leg as it gets closer and closer to being fit.

    its safely fit when the sear has no movement when engaged and the trigger is pulled.

    Familiarize yourself with the standard 1911 safety checks so you know how to test its functionality.

    Check the fit after every file pass when you get close.

    Only thing I can add is to make absolutely positively sure you really want the Extra Wide safetys.

    They are made for high-speed low-drag game guns, and are a PITA for everyday carry & use in a holster.

    Yep. Now that I have an ambi-safety, I could care less about it. I will probably go back to a single sided safety or whatever you want to call it. My 1911 is my most comfortable carry gun, and the ambi-safety just adds unnecessary width to a weapon that calls to me due to it's narrow width to begin width.

    I really don't know why I even bought it. I shoot just fine weak handed without an ambi-safety. It was a waste of my money to get a feature that sounds better in theory, but adds little functionality and adds width.

    On your weapon, installation should be a breeze. Just be sure to test it extensively before you carry it.

    Thanks for the great replys. I failed to mention that this particular firearm is for steel plate shooting. It is not a carry gun. Competition speed shooting. Wide thumb safety is necessary for my wide fat thumb to rest on. We do run stages in which weak single hand shooting is required on the run. I was perfectly happy with standard single side safety. Unfortunately. I was not allowed to shoot the stage with single safety! Thanks again for the input!!!!!!!

    The internal fit to the sear is obviously the most important point, but for longevity, you need to fit the right side (for your left thumb) to the top of the grip so that it is supported by the grip when your thumb is on it. If not, the pressure will loosen/weaken the tongue and groove joint over time. The other option is to fit a small stud on the right side for the paddle to sit on. That mod was developed by one of the pro smiths.
