Disable TP9SA Decocker

Many, myself included, don't like a decocker that leaves you with a dead trigger (no DA option). Does not affect the trigger at all.
 
I'm unfamiliar with the gun in question. I did just watch Hickock45's review. He likes it a lot. Sounds like a great gun.

When MUST you use the decocker?

What happens if you don't use the decocker?

Is the striker FULLY or only partially charged when the gun is ready to be fired?
 
It is a great gun, that's just it... You don't have to ever use the decocker. Once modded it has the exact same battery of arms as a glock, M&P, or XD. Striker fired and either fully cocked or fully decocked (after the trigger is pulled, while the gun is empty)

The Decocker was a hold over from the original TP9 which was DA/SA. The Decocker was used to put it in DA with a round in the chamber.
 
So, let me get this straight....
You removed the decocking ability from your pistol, which was placed there to remedy the possibility of an accidental/negligent discharge while disassembling?
The same discharge problem that S&W recognized when they developed the sear deactivation lever?


... And you think disabling a safety device is a 'good thing'?
 
Yea,theres no reason to unload your gun to clean it anymore,just depend on the decocker to tell you it is safe to disassemble your weapon.
 
I removed an unnecessary device that could leave you with a dead trigger and a bullet in the chamber. As others have already said, unload the firearm before cleaning and you'll be fine.

If this battery of arms were truly dangerous, 60% of police around the country wouldn't choose glocks.

In the end it is personal preference, feel free to leave your decocker the way it is.

Is this happening accidentally? I realize that there's always a finite possibility of something happening, but are we talking about a known problem or even about something that anyone has documented as ever happening at all?

I'm just trying to understand the rationale for the modification.
 
One handed manipulation drills, such as racking the slide off your belt, table, whatever. Not an "issue" per se, just a potential for ending up with an inability to fire the gun after an accidental decock (only an issue because this is a SA only firearm) in
 
...a potential for ... an accidental decock...

Right, I understand the "potential". It could happen since there's always a finite possibility of any control being manipulated accidentally.

What I'm curious about is if accidental decocks of TP9SA are an actual problem or even if it's something that has ever actually been documented as happening with this model.
 
I mentioned this in a thread I started a few days ago...


I can envision a scenario where you could accidentally decock the trigger... It isn't a huge risk, but the potential exists.

Owners piped in and said the decocker is not easy to push, which adds to the unlikely nature of accidental activation.


The decocker seems a holdover from the previous model that was DA/SA... That it is simply there because it was there on the prior model, and the slide and parts are identical, which lowers their need to stock different slide types. Maybe this was to allow them to release the new version quicker.

Having the decocker does allow them to tout it as a safety feature. Because...

The only time the decocker is used is during disassembly... Even then, its not needed. You can disassemble like a Glock, by pulling the trigger. The M&P line has the little lever to allow disassembly without a trigger pull, but I have used it only once, just to do it, the entire time I have owned my M&P.


As I understand it, they are about to release a version of the SA version without a decocker. it is listed on their website anyway.
 
In the review he claims to have experienced the pistol decocking while doing one handed manipulations using the rear sight off a belt. Take it FWIW.

Interesting. Thanks for the link.

Some sources say that it's not possible to decock the TP9SA unless it's in battery. If that's true, one might decock the gun during the start of the one-handed rack but as soon as the slide is released from the surface being used for the process, the decocker would release. That release would happen long before the gun returned to battery.

Again, assuming that's true, to actually decock the gun during a one-handed rack, one would have to press the gun back against the belt (or whatever surface is being used) after the rack was complete and the slide had returned to battery.

Remember this is based off of, thought not a true clone, of the Walther P99. The Walther P99 QA, to which this Canik TP9-SA is similar, had the exact same setup. Afterwards Walther gave us the PPQ which was the P99 RAD before that. Basically Canik is playing every page of the Walther handbook.

I don't say I understand how it happened to him. You asked for an example and I gave one. I don't think it's a huge issue myself, but it would still keep me from buying the pistol as opposed to other options. Supposedly they will release a version without the decocker, as has been said.

Sure, I understand. I'm just trying to reconcile his report with other information on the gun given that the two seem to be contradictory.

I believe I've solved the mystery by watching the video. His one handed racking technique is a little different. It can be seen at about 4:04 in the video.

He's actually racking the slide using the front of the slide and catching the front of the slide in his pocket. That exerts enough pressure to release the slide catch on the locked back slide. The problem is that he's got to actually pull the gun back up out of his pocket and apparently when he does that, he's bumping the slide of the gun against something some of the time after the gun is back in battery.

I've always seen a one-handed rack taught such that the rear sight is caught on the belt and the gun is pushed down to rack the slide. Then when the slide is fully back, the gun is pushed out away from the belt so that the slide is released to snap into battery. If done that way, (and assuming that the gun can't be decocked out of battery) then there's no way to accidentally decock the gun in the process.

I'm not sure I am seeing the same thing you are. I watched that section and the camera angle isn't good, but front what I can tell he is in fact using his belt to catch the rear sight (backed up by what he says in the video). I can see how you would think he was using his pocket and I'd almost think the same, but I do think it is his belt not the pocket. The pistol is in the pocket as he is simulating a one handed reload, but I would think the fullsize guide rod and the tightness of the pocket would make it pretty hard to use the pocket itself to get leverage on the front of the slide.

Your comments thought about where in the process of the slide travel the decocking is occurring and how it shouldn't cause this also make sense to me too. I'd really want to try this myself.

Here's a series of frames with the video time shown.

Here he's just starting the process and the gun muzzle is outside his pocket. He's taken the gun out of his pocket after loading the magazine and is now starting the one-handed rack to charge the chamber.

Here he's inserted the muzzle in his pocket to start the one-handed rack but hasn't pushed down hard yet.

Here he's halfway through his one-handed rack and the slide/barrel is inside his pocket with the dustcover outside of it. He's pushed down as far as he can go and to complete the process, now he's going to have to pull the gun up to clear the slide/barrel out of his pocket.

And the last frame, he's pulled the gun up and gotten the slide/barrel out of his pocket.

At this point the gun is returned to battery and if he bumps the decocker on something it will decock the gun.

A very different technique--but I guess it works for him.

What caught my eye is that he was pulling the gun straight back up vertically before presenting it to the target. With a normal one-handed rack, all you have to do is push down and then bring the gun up all in one motion. The sight slides off the belt during the downward stroke and there's no need to lift the gun back up to clear the sight from the belt.

With his technique you have to release the pressure on the slide by raising the gun vertically back up out of the pocket--you have to reverse the motion of pushing it down before you can bring it up on target because otherwise the muzzle will still be in the pocket.
