2 Star Firestar .45s have been perfect. I sold the first one to buy an Egyptian Maadi AK.
I sold the AK to buy a Marlin .44 Mag. I bought the second Firestar because I missed the first one. I often think about selling the Firestar. Then, I shoot it and forget about selling it.
Never a problem with that gun. I had bought two spare mags in 1993 that weren't worth a dang. Swapped them out at the distributor for two more that were perfect.
ATI Commander .45 has been great EXCEPT for the soft ejector.
Taurus Judge has been perfect. It always works. It is a great snake gun with .410 birdshot. I bought it for a snake gun and a range toy. Didn't care about the hype or the hate.
S&W 4566. Perfect in every way.
AMT Government model. Slide was very tight to frame and the frame and slide rails had the same matte/rough sand/bead blasted finish as the outside of the gun.
Jammed every 1-2 rounds with ball. Wouldn't even chamber HP.
Spent an entire day with that gun in pieces and two Arkansas oilstones, and a Dremel with felt bobs and different polishing pastes and impregnated rubber points.
After that, it was 100% reliable, had a great trigger, and was accurate.
It was even reliable with the Speer 200 grain Flying Ashtray (the acid test of .45 autopistol feed reliability).
EAA Witness .45. Perfect.
Rexio break open single shot .45 Colt/.410.
You have to aim it up to cock it. Otherwise, the transfer bar hits the firing pin.
It's in a box, in pieces. Awaiting a "round tuit" for me to either modify the transfer bar or design/make a new one. Or, shorten and/or further radius the back of the firing pin.
So, the AMT sucked out of the box, but was great after I put a lot of time and work into it.
The Rexio sucked out of the box and I still need to get inspired enough to fix it.
The EAA/Smith/Star have been perfect.
The ATI is great except for the factory ejector.
To be fair, I knew it may or may not have a soft ejector before I bought one.
I bought it with the idea of replacing ejector, slide stop, and safety with Ed Brown or Wilson parts. I want the extended slide stop and I need an ambidextrous safety.
I also bought it with the idea of milling the slide for Novak LoMount night sights.
