Glock Performance Trigger in Gen 3 frame?

I have read that the Gen 5 back plate isn't even necessary.

Either way, please keep us posted on your progress with this.

Using a standard, unmodified back plate, you wouldn't even be able to mount the slide onto the frame.

You can enlarge the right side cutout of the back plate, but a new gen5 back plate is a few dollars.

Benner, go here. I can't embed the video because it's age-restricted: Glock performance trigger modified for Gen 1 through 4

Thank you, Para. I watched that several times. I believe it looks like the legs on the trigger housing, the back plate and the hook for the firing pin safety on the trigger housing "hook". Those three things and this should work on my gen 3 G26.

I wish the video showed more of what he removed on that hook on the trigger housing. I under why he did but I can't see how much he actually takes off. Also, the metal hook below the polymer hook, looks like he took off some of that with his diamond impregnated wheel on the dremel.

Very informative and gives this old gun guy some hope.

Too bad that Glock doesn't sell the GPT trigger mechanism housing separately, because then you could experiment with it.

I'll be trying this soon myself.

I completely agree. But, I will be getting another one soon for my G26. I have one in my G19 gen5.

The best place I have found to purchase is primary arms with a log in. It shows it for $80.99.

You can also buy a gen 3 timney trigger unit that works on the same concept

At 8:28 in the video, he says "With all the Poly 80s and all the different guns, I'm just worried about this is gonna hit this..."

It sounds like his concern is the effect of variances in all the clones. I intend to round the top of that bevel in the TMH ever so slightly so that engagement with the FPS is at a less acute angle. Just smooth it a bit, and I think it will be fine, but if not, you can always take a bit more off of it. Removing too much would be worse than leaving it alone. I'm not convinced that this part of the modification is necessary. The proof will be in the shooting.

At 11:01 in the video you can see the differences in that part of the TMH between stock and modified.

The part you refer to as the "metal hook below the polymer hook" is the sear holder, and I don't see him making any changes to that part, nor would I think it necessary, because that part of the mechanism meshes with the trigger bar. I see him using his mounted Dremel to smooth the top of the TMH after rounding it off.

You're not going to be grinding any metal in this modification, just two different areas of the trigger mechanism housing.

I'll probably get around to trying this out sometime this week.

Excellent explanation. What you described makes perfect sense to me and makes me feel better about the hook on the TMH.

I, too, will be doing this. I appreciate you taking the time to note the video and times and then typing it all out. The 11 min mark I couldn’t tell if there was any metal but you answered that for me.

I think this will be a very simple mod to make the GPT work in my beloved 26.
