I purchased the Walther P22QD Tactical FDE pistol and have had no issues with ammo so far. .My issue is the front Hi Vis sight is loose. It has the small screw on the bottom inside the top of the slide to hold it in place. Problem is that after shooting it has worked loose enough to wiggle around. The way the screw is located it is impossible to get a straight screwdriver into the screw to tighten it up because the part of the slide that the barrel slides through is in the way of getting a screw driver into it. Has anyone else had this issue and if so, how did you get the screw tightened up.

Welcome MACOX, that is a good question. I don't have that sight but I can easily understand your question.



Not a great picture but it shows the problem with the end of the muzzle blocking access to where the screw would be centered. Ignore the O ring....which is what this picture was originally about.

I've pictured a regular sight blade with the expanded tabs on the bottom that need to be spread under the slide. You have something similar but with a screw in the center which spreads the bottom legs for a firm fit. If a small screwdriver can't be angled in I don't know what to tell you. The screw can't be tightened too much because I think the sight base is polymer I think. There are no common tools that I know of that are small enough to fit inside the 1/2" opening....a 90 degree screwdriver for example. If the head fits an Allen wrench perhaps a ground off one would fit or perhaps if the screw isn't an Allen headed one it could be replaced with something of the same size/shape. The second question is how to keep it tight once installed and tightened. The barrel sleeve runs immediately below the screw....so it really doesn't have room to back out before dragging on the sleeve. Perhaps loctite if that glue doesn't melt the sight base. 1917

BTW, it seems I read that the sight comes with an Allen head screw and wrench. If the wrench doesn't work, there are models of this wrench that have a ball shaped head which is designed for an off angle fit. They are pretty common. 1917

Here is a quick link to some.....you should be able to purchase something similar at auto stores, Lowes, Home Depot but it seems the sight would have come with a proper wrench. 1917

Im going to take some diamond files to my Gen II P22 slide and install this.
It should fit and clear the barrel.

If you are talking about filing a dovetail into the slide....I wouldn't. The slide is a cast zinc alloy, the metal is extremely thin and that is an area that takes a lot of impact since the muzzle cup just beneath the sight takes the impact of stopping the slide's rearward movement. That means a lot of stress when hitting the take down lever. If you choose to follow through, keep us posted with some photos of the cut, fitment and how it holds up please. Ft Smith has new slides but I would not expect them to replace the slide with this type of modification. 1917

There already is a big front sight mounting hole in the top of the slide.
The bottom front slide return spring drop-down hits the slide lock bump stop. That puts compression forces on the top surface of the slide.
The dovetail sight hasnt arrived yet so i just stuck an OEM nylon sight in it for now.

Venting the front return spring chamber finally made my Gen ll fire every time after deburring, fitting, and polishing for 10 hours, lol.

6 years of Single Action target practice got old...Remington High Velocity will cycle so fast now that you can keep 3 extracted shells in the air at once before the first one hits the ground.

This pic is the roughed-in step in the 1/8" ports.

Clipping the return spring on my Gen ll from 25 coils to 22 coils reduced slide backpressure while still allowing slide lock release chambering from the mag.
You have to rebend the clipped end to lay flat against the pocket bottom in the barrel base hole, tho.
O-ring is only to stop the captured slide spring washer on the aftermarket captured spring from direct metal-to-metal recoil contact with the front of the slide.
