I'm thinking about picking up another da/sa revolver. These old war horses have caught my eye. How do those of you that have one like the fixed sights of the Service Six? I have a locked up 4" model 13 Smith that needs replaced.

"Locked up" model 13?
I dont know if the ejector rod has loosened up or what is going on with it. I got it from my dad when he passed away. It's in pretty rough shape and he had it drilled for an old red dot scope. I'll pull it out this weekend and work on it.

I have a couple N frames that have never given my issues but this is the second K frame I've had that prefers 38s to 357s.

Ruger did a really good job regulating the fixed sights on the Service Six's. At 15 to 20 yards my 2 3/4" six shoots POAim with most ammo in the 158gr level, while the hot 125's are not so much. I'm not so interested in trying any 180gr loads but that may be because I haven't come across any yet.
 
Just as with any fixed sight handguns, you need to find the right combination of ammo to gun to get it to hit POI at POA. That said, you can also try different types/bullet weights and find the front and rear sight alignment that will provide POI at POA. With enough practice, as long as you remember what load you are carrying, you shouldn't have any trouble.

The Six series fixed sight revolvers (Security Six fixed sight (which later became the Police Service Six or Service Six depending on the contract)) and Speed Sixes are great guns that if not abused will last several peoples lifetimes.

I wish I had your 13 as a "project" gun...I would cut it to 3", install a C&S fixed rear, mate it to a FO front, round the butt ( if not already, most aren't), cut the forcing cone for lead wadcutters, crown the barrel, obviously"unlock" it, do an action job...then find a good IWB holster and carry that bad boy,!
 
The "scalloped" frame Service Six and Speed Six guns have a thicker top strap and therefore, deeper sight channel.
 
Bought my Service Six in 1975.
Great shooter, but it now serves as my son's nightstand gun…

The ejector rod locking them up is common. Once you get it open, be sure to put at least 3 fired cases, never live rounds, in the cylinder to take the stress of tightening it up. The threads are left handed so it will be the reverse of normal threads.
 
Starline 38sp brass, MP 359-640 with penta hp pins cast from 20:1 and crimped in the top groove, powdercoated, CCI 550, 12.1gr 4227. Pressure is in the 38/44 class or heavy +p. @22,000 psi so use with caution.

Same load with the Keith bullet from MP 358429 mold is just as accurate, but under 20,000psi for +p.

50 yards. The Service Six does just fine with fixed sights using the right loads.
I like the fixed sights too, I haven't taken it to 50 yards yet but I was able to get 1.5 inch groups at 25 yards (actually 26.5, the furthest you can go at the local indoor range) with my 2.75 Speed Six. I was surprised it did just as well as my 4 inch Security Six. I should have taken pics but the target looked like Swiss cheese at the end.
