I'm determined...mini red dot install on a P22.

Crete, the set up I have for the red dot works well. You could mount a picatinny rail, a short section of aluminum or any flat manufactured mount suitable for attaching a rear target sight. The slide can take it, the slide will cycle, you could even let the rear sight hang off the rear of the pistol for greater sight distance. Nothing is tricky about it except drilling in the correct place on the breech block. All you need is something like below. You might even be able to find a stock mount base that you could securely fasten, then add the sight to it. On the last base I made I removed the polymer sight, drilled a hole in the rear of the base mount so that it fits right over the loop. That holds the rear of the mount where it needs to sit. The only problem with hanging the base out past the rear of the pistol is you will have trouble getting a grip on the hammer for manual cocking. Moving the slide work fine for loading, unloading.
I think there are a number of manufacturers that make mounts that would be suitable. I have not broken a slide with the four holes drilled to date.....then again, a new slide is only a phone call away here. I know you have a more difficult time time even if you try to purchase one. I think some of the 1911 bases I've seen are the simplest. They are flat, the top of a P22 slide is flat. It seems some of those even have a dovetail built into them. Of course this is all going to change the height or your rear sight....but it would sure look neat and should be legal. 1917

Something like this, only move it to the rear of the slide, over the loop and use it to install fully adjustable target sights.

Well I just got my slide replaced and they wanted to see the old one so I had to send it in. I think I might just install a laser to the rail under the barrel. Not about to mess with modifying the slide.

I wish I were able to add a bridge over and above the P22 rear sight, like in this Margolin MCM or Hammerli 208 (pictured).

It could be detachable too: snap on and off kind of contraption.

That way the rear sight picture would remain the same during shooting as the slide would do its business independently.

Crete, It seems the last time we had this discussion we came up with a plate or two, neatly folded over the top of the slide and clearing the rear sight. red part It was fastened with 3mm or 4mm screws through the existing roll pin holes that hold the grip on. On top of this would be mounted a target sight or a base for a target sight. Green and blue. The only negative is that to remove the slide you have to remove the sight mount. It would not matter what the mount or sight weighed as the slide would operate independently. With you fat grips a sharp edge wouldn't matter either at the bottom rear. There are also other spots holes could be drilled but you have to avoid the magazine, trigger bar, etc. 1917

Or something not so stylish but with holes for the safety and slide release arm. If you removed the stop arm and used a concept like #1 you could remove just one bolt and pivot the base up and out of the way of the slide without totally removing it. Still might have to re-zero. There also might be a way to slide a sight/mount on and off of the grip and perhaps it will retain zero since it would be fastened to the grip/frame and not the slide. You could probably find a Ferarri laying around some dark parking lot and cut out the pieces you need from the nose or perhaps a door.

This concept could also be a mounted on one side only piece too and avoid the left side of the pistol altogether. 1917

I doubt they are legal for the shooting Crete is doing. I have a Crimson Trace on a 1911 .45 and it works great....but I do not like target shooting with lasers for some reason. I've fired several P22s with them installed. I don't find them nearly as fast to aim and I don't like the shake they show me that I have....but they can be zeroed and where you hold that dot is where the round will hit. 82' might be a bit far for a laser. 1917

If you mount a 1/8" thick piece of aluminum to the top of the slide like this you can mount any flat base target sight to it by drilling holes and tapping where needed. Want the sight another inch or two to the rear....just drill a small hole where the sight loop is and let the aluminum base extend as far rearward as you want the sight. Carefully place the target sight, mark holes, drill and tap. The advantage of being mounted on the slide is that you can take the slide off for cleaning and not have to re-zero. The disadvantage is that you can't put a 1/2 lb sight up there or the slide won't cycle it. The front right hole allows access to the extractor pin. The two rear holes are for mounting the red dot shown. 1917

Nice solutions. I am sure they will work.
Only open sights for my ISSF matches, although none has been held since March-April 2020 due to the COVID-19 pandemic.

I was thinking of a bridge-like contraption like the one on the Margolin MCM: a Π ramp with rear sight attached w/two adjacent screws on either side of the top of the frame/grip, just below the slide.

A few years ago I built a contraption to hold a P22 similar to a ransom rest. I also measured the distance from my grip to the center of my wrist and located the pivot bolt there. Shown in the first photo is a short barrel under recoil. The pistol would flip up to the limits of the device. I also shot the 5" pistol and it too lifted the muzzle to the limit of the device...some 2" to 3". I then experimented with a dozen contraptions in an effort to dampen muzzle lift. On the 5" barrel I installed some 1" rings on the rail, a 1" piece of wood dowel, drilled a number of holes for locating the spring loaded damper various distances from the muzzle. Some where short, some way out there like shown above. And how did the pistol react.....muzzle lift was reduced to 1/4". Crete of course would have to cut the wood so the overall length of the pistol complied with rules and I made some that were within limits and the damper worked well on them. I also added a slim bridge glued to the top of the slide which allowed the front sight blade to extend to the max length allowed. That worked well too. As I recall I drilled three small holes in the top of the slide that matched three holes in the rail. Cleaned and stuck it down with JBWeld. Nothing came loose nor did the slide crack. This is the device I used to test barrel length and ammo in the 3.4" and 5" pistol and a Ruger MK III bull barrel. TheRuger was the champ with 3/8" groups while the 5" P22 was close behind at 5/8" groups.. 1917

The videos were in slow motion but I cannot figure out how to load them to Imgur or here....

I have a youtube channel somewhere....dang, I'd have to remember the password. One time they guys were complaining about an LCP hanging up when chambering a round....so, I made a video of my LCP chambering anything. I'd load the mag with fmj, hollowpoints, flat points....let the slide slowly forward until the nose was resting on the feed ramp and then let go. Everyone chambered. The problem was the front of the unlocking lug hitting the rear head on the guide rod. Decided I'd put some music to it....they kicked my music selection off saying it was copyrighted....so, I got out the guitar/strapped a harmonica around my neck and made my own music. That'll teach em. OK, when I get time I will see if I can find my U tub channel. 1917

Yep, they're on PPQ's and I used the Shield 'low mount' on all of em'. The notch in the rear of the Shield is a little wide for my liking when used with a standard width front sight. So, I installed one of my spare 'Speed Sights' front sight, which is wider. That sight is 'Perfect' for me as it fills up the notch with just a little .... very little light on either side. I've ordered more front sights.
