My opinion on slide mounted safeties/decockers

Plain and simple, I don’t like slide mounted safeties/decockers because…

1. They can cut my hand and make my grip slippery with blood.

2. They can be swiped into the “safe” condition when doing the overhand technique of manipulating the slide.

3. They can be swiped into the decocked condition which can be distracting and affect my accuracy and ultimately leave me vulnerable to being shot due to missing my target.

Here is how I came up with my opinions.

Many moons ago while in the military, I used to carry the Beretta M9 (9mm) handgun on my chest in a cross draw rig. I currently carry the S&W4006TSW tactical (40cal) as my dept. issued duty weapon.

If you don’t already know, both these guns have one huge feature in common…they both have slide mounted safeties and decokcers. (the safety is also the decocker combined) After a few years of past experience and current experience carrying this gun I have developed a first hand opinion on slide mounted safeties & decockers. For this topic I will refer slide mounted safeties/decockers as SMS’s to keep life simple.

If you ever ran your handgun through a demanding course of fire where you are forced to run, shoot from cover, from your back, shoot on the move, navigate through doors and rooms and hallways ect ect, and deal with malfunctions…all under stress and adrenaline…you may know what I am about to say?

When I experienced a malfunction, I did what was drilled into me for years, which is “tap, rack, bang!” Of course there are variations of the wording of this method now but you get the point. And no matter what level of malfunction there is, it usually involves manipulating or “racking” the slide with an “over the top” or “over hand” technique.

This is a part of my DNA now and I can’t remove it without some type of psychological brainwashing, lol. One time on the range after hours and hours of performing this “overhand” technique I noticed a warm wet feeling on my support hand. It was blood.

I had gripped that slide and rear sight with enough force to rip open the skin on my palm. Not so much a problem on my Beretta M9 but on the sights of the S&W4006. They are large, sharp and adjustable. Btw, I am also not a fan of adjustable sights on a fighting handgun but that’s a whole other topic.

Now this may not be a big deal since I will not die of blood loss obviously and in a real gun fight, adrenaline won’t allow me to feel the low level pain of a cut palm. The real problem is that my grip could get compromised due to the slickness of my blood. If this affects my shot placement then I could actually die from missing a critical shot on the bad guy who in turn takes advantage of my disadvantage.

At the end of the day, accuracy wins the day even though it’s popular to say “speed is life” on the battlefield.

So as you can see a small seemingly insignificant issue can turn into a real life and death issue in a split second due to a slippery grip.

Another big reason why I am not a fan of of SMS’s is not 100% the guns fault but a training issue. It is possible to do the “over hand” technique and accidentally swipe the safety into the “ON” position.

How is this possible? Well some hands are bigger (or in my case fatter) than others and my palm or fingers or both can push down on the SMS lever, actually pushing it all the way into the safe position.

This is obviously possible because the SMS lever is mounted high and pushing it “DOWN” is the safe position, whereas if it where mounted low on the frame and the action to put it on safe where “UP” (like on a 1911 or HK USP and others) it becomes almost impossible to accidentally swipe your gun into a safe/no fire condition. 

On my S&W4006 if I did this in a life and death gun fight…I would obviously put myself in danger. I’d have to have the presence of mind to recognize my mistake, take my focus off the threat (or threats) refocus on my gun to identify my problem, fix it by flicking the safety “OFF”, refocus back out onto the threat and get back into the fight.

For some, this whole process might only take a second or 2 to recognize and fix? But as you know, 1 or 2 seconds is all it takes to loose in a gun fight. Again, this is where that old saying “speed is life”. Accuracy won’t matter if your gun is on safe!!!

Now on some models, like the HK USP if you accidentally swipe the frame mounted safety/decocker lever all the way down past safe, all you will do is decock the gun and be forced to shoot the next round in double action mode. That’s the mode that requires a heavy trigger pull. This can be distracting and throw off your accuracy but at least you are still in the fight.

Now keep in mind many folks never experience what I did. And even folks with big or fat hands may not experience what I did. This is just my personal experience.

If you have a gun with a slide mounted safety/decocker and you are effective and accurate with it, don’t change your setup. You have found what works for you, and in the end that’s what you really need in a defensive/fighting handgun. You just need a gun that fits you and that you shoot accurately with.

Stay safe.
