The good the bad and the ugly.
I gave up. I no longer can clearly see the iron sights after about 10 rounds. A big black blurr of front sight & target. Father time has crept up and whacked me on the back of the head.
So I decided to mount an open reflex sight on my beloved K38. Bought the mount from Alchin gun parts and the inexpensive RDS through ebay. With the help of a friend, got it all assembled, went to my club & proceeded to zero it.
The good: The green dot is right where the bullet goes, The green dot is clearly visible as is the target and its X ring. The green dot is easily picked up as I bring the revolver up to firing position. Oh Happy Days!
The bad: The adjustments to zero the dot are sketchy, a little movement & the dot moves a lot, a lot of movement the dot moves very little.
The ugly: The lock screws to lock the adjustment in place, do NOT work. Two days after zeroing and locking down the adjustments, I competed in my club's PPC match. The revolver now was shooting 6" low and 5" right at 7 yards ( ! ) Kentucky windage (& elevation) was used as no time to adjust again) Then about half way through the match, the green light went out. Finished the string using the backup U groove in the RDS and front sight. 6 rounds off paper. Turns out the U notch is only an advertising gimmick. Fiddled with the unit & got the green light back on & finished the match, still shooting low right.
Needless to say, I did not win the match.
Conclusions:
1, The Alchin mount is excellent, strong and durable, well worth the cost in dollars and labor to mount.
2, The concept of an open RDS with it's little green dot for POI is excellent, especially for aging eyes. NO problems finding it, No problems seeing it and the target.
3, A cheap RDS while appearing to be a wise financial choice was a disaster. When it worked, it proved the concept and function. When it worked it was excellent, it made it possible for me to shoot accurately (or at least as accurately as I can shoot) for the entire match.
4, A new Holosun RDS is on order as I type this. Not cheap but well regarded and reliable.
5, I should know better than to cheap out on optics.

Sounds like you got it all figured out. You should be happy with the Holosun, they are good sights.

By the way, RMR is a specific model of Trijicon. RDS (red dot sight) is a general term usually used for that type of sight, though many times they are actually green dots or circle/dots.

Bingo.

I've put these Holosuns on a few firearms I own...I had a problem with one but they sent me a new one, no charge. Took about a week.]
 
Red dots are a Godsend. I learned long ago about cheap optics but for my first red dot, I bought the el cheapo $30 BSA from Walmart, just as a proof of concept. It's never been on anything but a .22 but 20yrs later the damned thing is still running. I think the Holosun will serve you much better though.

Yes. Yes you should. The Holosun or similar is what should have been done the first time around. Most of us learn that lesson the hard way, and need reminders sometimes after the initial lesson. I know I did.
I hope you get to enjoy shooting your revolver again.

Yes, but it's hard to get over how expensive good red dots are. I managed to get a heavily discounted Gen1 RMR for about $350 when Gen2 came out, and that was considered a bargain. The new ones were about $800. It's a good thing Holosun and Swampfox exist, although I'm not sure I can trust those yet.

The new ones are $450-$500 all day long.

EGW mount. Only one frame mounting screw (maybe updated, don't know) so possibly best to use in low recoil situations. Didn't shoot a lot, but held up fine on M69 w/.44 mags.
