Hi, all; first post here and I'm hoping you can help with some questions I have on my new-to-me revolver. I've been doing research here and anywhere else I can on the internet, but information is slow in coming so I finally joined to seek some knowledge here.

TLDR Version: Looking for options for a front sight on a Model 22-4, Model of 1950.

A few years ago I decided to "standardize" the calibers of firearms I own, so for pistols, I focused on 45 ACP. I had a 1991A1 my dad gave me as a gift after my first year in the Army, and keeping with that caliber, I branched into revolvers. This was about the time the S&W "Classics" line came out offering the 1917 and the 22-4. Their cost kept me at bay for a long time, so I went looking for some used revolvers.

First was a Brazilian 1917 with a 5.5" barrel. It was reblued before I got it, but looks like it was professionally done and it shoots great. Then, wanting a shorter barrel, I found another 1917, a U.S. issue revolver. It's previous owner had cut barrel to 4" and had a replacement ramp sight installed; however, the revolver was in rougher shape. I purchased an oversize hand from Midway and a gunsmith replaced it to correct slightly slow timing on a few cylinders (the original hand's tension pin was bent and eventually broke). He also swapped a a NOS serrated trigger for the original, smooth one. (The gunsmith replaced the pin on the old hand, and I kept the original hand/trigger as backups.)

Looking for the parts for these old revolvers is no easy task, so I decided I'd bite the bullet and look for a modern 45 ACP wheelgun. I like the old wood and blue steel revolvers, so the modern synthetics weren't going to be an option. I waited, bid on (and lost) a few auctions, but I finally got a Model 22-4, Model of 1950 this fall. It's serial number is somewhat lower, less than CMA1000, so I question if it's affected by the too high front blade. Shooting it with standard 230 gr FMJs, they all placed low and right of POA at about 20m. Being at least second-hand, I have no idea if the original owner had it dealt with at any point in the past.

I'm not at all a fan of the half-moon sight (never was), so I've started looking for a replacement ramp. A serrated black ramp is fine, but a serrated black ramp with red insert is preferred. Evidently, everything is back-ordered at Midway and Brownell's. S&W offers a package of 4, but only one is the style I want, and at $60+ for the lot, it makes it too pricey to keep just one.

I'm assuming my revolver's sight has the crescent-shaped bottom and not the "dovetailed" interchangeable sight, and I'm guessing its .250 in height. I don't have calipers, so I can't be sure. I've found and I'm considering a ramp sight from Dawson Precision, in .230 height to correct the POA/POI problem. There's also Numrich, and they do list sights for N-frames, but I was too late in calling them yesterday afternoon to check what they have. They don't really list the heights of their sights.

Since I thought getting something made in the past 10 years would alleviate some of the headache finding replacement parts, I'm slightly irritated, but undaunted. I'll find that ramp sight.

If you made it through all this, THANKS! I appreciate any help the community may offer up.
