One of the most commonly replaced parts on any 1911 is the thumb safety. Unfortunately, the safety system on a 1911 can seem very complicated and you may be hesitant to work on it yourself. Rest assured, replacement of the safety is a simple task. Anyone can do it with a bit of patience and the right procedure to follow. Whether you are replacing the stock safety with an ambidextrous safety, or adding an extra-large single-sided safety, the procedure is basically the same. This guide will work on almost all 1911’s. If you are having difficulty removing any part of your pistol, stop and take the pistol to a qualified gunsmith. No operation in the tutorial should be difficult to complete. Here is how you do it:
First, make sure your pistol is unloaded. You may want to field strip the pistol to make it easier to handle, but that is not absolutely necessary. If so, remove the slide, barrel, and guide rod assembly. Remove the grip panels and set them aside.
Next, place the pistol’s safety halfway between “engaged” and “off.” It may be tricky to get it to stay in the middle position, so you may have to combine this step with the next one. (continued below)
Use a small drift (brass is preferable) to push the safety out of the frame of the pistol from the right side. If you have an ambidextrous safety, you must pull the right side out of the frame prior to using a drift to remove the left side (it should come out easily - no tool required). If you are having difficulty, check to make sure the safety is in the middle position. You may have to wiggle the safety slightly to get it to disengage.
IMPORTANT: Do not lower the hammer, pull the trigger, or otherwise mess with the pistol. Keep it in the same configuration as when you removed the safety.
To install the safety, gently slide the left side into the frame so the safety is oriented to the “middle” position of the safety detents - just like when you removed it from the frame. If you have an ambidextrous safety, insert the right side after the left side is in the frame. Make sure the safety is tight against the frame of the pistol (on both sides if applicable). IMPORTANT: The safety parts should go smoothly and easily into the frame. If there is much resistance, STOP and examine the parts. Make sure the beavertail safety has not been moved or that the trigger has not released the hammer. If you have problems inserting the parts, contact a local gunsmith or contact me and I will help you.
Reinstall the grip panels (keep in mind the grip panels hold the right side of an ambidextrous safety assembly in the frame) and reassemble the pistol (if it was field stripped).
Test the safety to make sure it functions properly. Cock the hammer, grip the pistol, and pull the trigger. The hammer should fall without hesitation. Next, engage the thumb safety, cock the hammer, grip the pistol, and pull the trigger. The hammer should not move at all, even with significant trigger pressure. Next, engage the safety, cock the hammer, DO NOT GRIP the pistol, and pull the trigger. Again, the hammer should not fall. It is important to test the operation of the safety with and without engagement of the beavertail safety. Failure to do so could lead to a negligent discharge and risk of injury or death. Always keep in mind that the safety systems on the 1911, and any other model pistol, are mechanical devices WHICH CAN FAIL. Do not substitute proper safe handling techniques with reliance on a mechanical safety. Always follow the four rules of gun safety:
- Never point a gun at anything you do not intend to shoot (and kill).
- Keep your finger off the trigger until ready to fire.
- Never load your gun until you’re ready to shoot.
- Know your target and what lies beyond it.
Hopefully, you have removed and reinstalled your safety successfully. If you are having problems, I suggest you contact a local gunsmith, or get in touch with me and I will talk you through it.
