Time & time again, I see people add unnecessary aftermarket parts to defensive or duty handguns. Many people try to replace training and practices with a mechanical device. Generally what happens, they replace the part with a new part which requires more motor skills to operate.
By doing this, it requires more time, effort, and energy to perform the skill; this is often counterproductive and a waste of money. The number one part I have seen replaced or altered is the trigger group. I tell people to typically avoid altering this area.
First, you have to remember the context the handgun is being used. It will be used when the person’s life is on the line when they will have adrenaline pumping through their system. When this happens, it is much harder to perform fine motor skills. So you have to ask yourself, why would you want a lighter trigger or a short pull from the original design? If you have a gun that has a 9lb trigger pull and a one inch pull, do not use that gun. It is generally an old design and usually costs a lot more. Remember, the people who design these firearms have made it that way for a reason. Some of the reasons are the best in the world, but, go with a design that all you would have to replace is the sights. If it has plastic sights, replace with steel sights. This does not mean you have to add expensive competition sights, you can keep the normal notch and post style sights.
Now there are some alterations you can make without changing how the gun operates. An extend magazine release is fine, as long as your weak hand does not release the magazine as you establish your grip. Another part which is acceptable is an extend slide stop. Yes that reads slide stop. By adding an extend slide stop, it aids in locking the slide back to the rear when clearing malfunctions.
Keep everything else the same. Generally, as soon as you start changing the internal components of the gun, the reliability goes down. I see people doing this all the time. I usually hear, “well I paid for it.” I asked them how much their life is worth or how much they would pay to see a loved one again. The second part is always worth more than the aftermarket part they should have never bought.
You cannot afford to be attacked. Do not allow yourself to become a statistic or a story on the news. Get yourself training.
