FMK Problems

[Ganderite]

The FMK Gen 2 is a clone of the Glock 19. (I own both, and the inside of the frame is very similar.)

If you are not familiar with the FMK, maybe you can recognize the issue with Glock experience.

I have 2 FMK Gen pistols. An early one and a later one. The later one runs well (very well for a $179 pistol) It is the one in the middle.

The problem is that when I shoot, the slide returns to battery, but stops, about 1/10th of an inch short of lock up. The slide then closes when I release the trigger, to re-set. The other one does not do this.

The problem is that a slide is supposed to slam shut, locking everything up. I am getting misfires, and I suspect it is because the slide in not quite closed.

Springs not strong enough?
Dragging on the mag lips?
Feed ramp deccelerating the round as it chambers, and therefore slowing down the slide?

It does this with no mag, when dry firing. Slide jumps forward 1/10 inch when trigger released/

Sounds like the disconnect is not working properly, maybe burred or deformed?

There is a hump on the trigger bar, that pushes down as the slide moves back.

I assume this is the disconnect?

I will compare the two pistols, and see if I can see a difference.

I have both frames in hand and I see a difference in the trigger cruciforms. The good pistol has a longer rear tab.

Could this be an issue?
