As original poster said 3 out of 4 had to go in for service, there is nothing I can do and frankly don't see light at the end of the tunnel.
I rarely give second chance and never 3rd let alone 4th.
Not sure if original poster used these when dryfiring:

This will spare firing pin hole and the firing pin itself by dampening the hammer fall.
I didn't have any commercial ones so I made 12 of these in about 10 to 15 minutes.
What did you use for the primer pocket filler?
I have some that I used a hot glue gun to fill the pocket. It has some give to it, but I am concerned it isn’t enough.

Regarding new Colts and new revolvers in general:
I was tempted to buy a Colt Cobra when they came out, but the complaints about them and their reliability made me cautious and I decided to wait. Now it’s a few years later and Colt prices and reliability issues have me convinced I will never own a new Colt.
But it’s not just Colt. Smith & Wesson and Ruger also have issues.
Smith & Wesson: In the past few years I have bought 3 brand new S&W revolvers. A model 60 Pro, a model 63-5 and a model 25-15.
I had ridiculous issues with the 60 Pro. The barrel kept turning, canting the front sight.
The model 63 had terrible accuracy and a barrel to cylinder gap of .012-.013”. I sent it back. A new barrel was installed. The B/C gap was .005”. Nice, right? Well, that repair didn’t do anything to remedy the terrible accuracy.
The model 25-15 has a blemish in the barrel coating S&W calls bluing. It’s like a scratch. The gun store assured me it came that way from the factory. I called S&W about it. They said they could fix it and they would remove the barrel to perform the fix. Judging by the “repairs” of the last two new revolvers I sent them I figured they would somehow screw up my very accurate model 25 so I decided the blemish does not bother me after all.
Ruger: I bought a new Ruger New Vaquero .45 in 2020. It ran fine for about 400 rounds and it started skipping chambers. Cleaning and lubrication didn’t fix the issue so I sent it to Ruger. While it was there I had them make me a .45 ACP cylinder for it. The ratchets on the new cylinder were not ffinished. They were very rough, like someone was in a hurry. The chambers line up with the bore, but occasionally the gun locks up when drawing the hammer back when the .45 ACP cylinder is in the gun. The hand gets bound up in the ratchets. I am afraid to file and polish the ratchets because I don’t want to throw off the timing / chamber to bore alignment. I don’t want to send the gun and cylinder back because i modified the gun with a Vaquero/Blackhawk grip frame after receiving the repaired gun and cylinder. I gave the original grip frame to a friend. I am not sure Ruger will fix it and they’ll probably say the new grip frame somehow interferes with the operation of the gun, which would be incorrect as the problem existed before the new larger grip frame.
I bought a slightly used GP100 in ‘22. It was used but only had 50 rounds through it. I liked the gun, but just could not find a load in .38 Special or .357 Magnum that it shot accurately. I am not talking trying a few factory loads. I am talking lots of hand loads going all the way from the lowest to highest powder charges with 5 different powders all with 158 grain bullets. I started to experiment with 125 and 130 grain bullets and gave up. It didn’t even shoot my Wadcutter loads well and they are accurate from all my other .38/.357 revolvers. I sold the GP100 and the guy knows why I sold it.
Life’s too short to have a frustrating unpaid QA Inspector position when you have to buy the test samples yourself.
