When I pull the slide, after about 1 centimeter (0.4 inch), something inside seems to clinging. As if a sharp point is clinging (sticking?) to an edge.
Pulling to the end, the firing pin is cocked and overall the operation of the gun is not affected.
This only happens with the Glock Performance Trigger (GPT) trigger installed on a G45 Gen 5.
As I said, the pistol is OK but my OCD can not ignore the problem.

Am I the only one who report ?
Or this is a common issue for the Glock Performance Trigger?

Thanks for reply!
As you suggested I read those threads but my problem is some how different.
Indeed, the G45 have a G19 slide but except that "catch" everything is OK.
Is happening all the time, at every pull the slide, for only a tiny fraction of second and then snaps...

John, someone who is an Armorer here may possibly know and answer but if you don’t get a reply maybe give Glock a call and see if they can help. I don’t have a gun with the GPT nor do I own a Gen 5 gun. Good luck.

Yes, I will send a message to Glock Austria but only after I will wait a while to see if this issue is know also by other forum users.

Ohh, Ohh ..... Not that I'm looking to get into a stupid argument; but, in order to answer this question, I think I'm going to have to criticize the 'sacred grail', so to speak.

Over the years, I've noticed that Glock pistols are essentially designed for right handed people to shoot. You can prove this to yourself by performing a simple test:

First, fire a Glock pistol with your right hand and notice the trigger pull weight.

Then, fire that same Glock pistol with your left hand and notice the change in the trigger pull weight— It's going to be less smooth and perceptibly heavier!

Why does this happen? It happens because the Glock design uses a single trigger bar running down the right side of the frame rather than dual trigger bars running down both sides.

Whenever a Glock pistol is used with the left hand the trigger bar becomes torqued. It will rub against both the striker safety, as well as the right side of the frame. It's less smooth, and the trigger pull weight will increase.

In my opinion, it's this tendency for Glock's right-side trigger bar to torque and/or to rub ever so slightly against the frame that is causing, even more noticeable, binding problems with these new 'GPT' triggers.

"the Glock design uses a single trigger bar running down the right side of the frame rather than dual trigger bars running down both sides."

I've also thought about the trigger bar and possible implications/actions etc.

I wonder if this also tends to cause right-handed shooters to shoot low, left when they are first learning the Glock trigger. Just a thought...

 

[Hoss]

Wouldn’t there be evidence of the TB rubbing on the frame after time? I did not ask John if he has actually shot the gun with the GPT in it or just done dry fire? John, I think one of the links I posted addressed this but I know you said your situation is different. Might be worth a closer inspection.

I hear you; but, personally, I do not think so.

(Low left shooting for a right-hander is caused by the pistol being allowed to break toward the weakest part of the grasping right hand—the fingertips!)

Good question! Personally, I do not think so; and I'll tell you why: The potential wear is similar to that of a metal part running inside of a frictionless nylon bearing. It just isn't that significant.

OP - I believe your post #27 in the following thread answers your question:

Glock 19 - Glock Performance Trigger, frame flex and slide stop activation | Page 2 | Glock Talk

Seems like the extended slide stop lever (aka release) is leading to the problem.

Edit: after rereading the threads my response seems to be about your frame flexing situation not the "smoothness" of your GPT.
My 02 cents - take a look at @TexasPOff post #13.

Post a pic of the inside of your slide. My guess is the trigger bar extension is rubbing against the hood of the slide. I've had to file many of these to improve the interaction. Either that or you can remove the lubrication and hand rack the slide a few hundred times, clean, and relubricate to see if that improves the feel.

 

[TexasPOff]

It sounds like a burr either on the striker block itself, or the inside of the striker block channel on the slide. I have seen this before, and because it is only occurring with your G45 slide, this could be the problem.

Remove the striker block only, and test. If the "catching" is gone, then you have your answer. If it is a burr, it will wear off with use. I don't recommend removing it yourself unless you have the knowledge and proper tools.

It won't effect the function of the pistol, just bother your OCD until it wears in.

Low left isn't a problem with the gun
It's a problem with the skill of the shooter.

Photos would be helpful in order to see where the drag is occurring...

Yes and no. For the most part your statement is basically true.

However, let's examine this:

Like many others, I have shot handguns for years.

I always shot 1911's and CZ's without shooting low left (right handed). Think about the trigger bar design here.

Years ago when I first shot Glocks - low left hits. Did I suddenly forget how to hold and shoot a handgun?

My point is this - different handguns have different designs and you must learn to shoot them accordingly.

Remember my opening statement - "For the most part your statement is basically true".

 

[cciman]

You are not racking 0.4in when shooting.

OCD, ignore it.

Too much fine tooth combing and microscoping for problems.

 

[9x45]

Did it work with the OEM trigger? Did you function fire it first before installing the GPT?

The chart is for one handed Bullseye shooting.

That's been my experience as well, the 1911 has a well designed trigger, John browning pretty much got it right with that design.
