Hoping to get some guidance on possible causes of problems and solutions.
Ruger Security Six 357 Mag 4" Barrel 1976 Model:
Seems like it will become a great gun. Fun to shoot. I was reasonably accurate with it first time out.
Four barrels work fine - long smooth trigger pull and I can "stage it" (pull trigger half way to just before release point if I want for better accuracy).
On two barrels the trigger is very hard to pull or sometimes won't pull. When it does, it pulls right through to firing the bullet without being able to stage it (perhaps because it took so much pressure to move it). I sometimes have to cock it for single action to be able to shoot when trigger gets this way.
On my last revolver with timing issues (gods, can I get some luck please?) the trigger was never hard to pull, it was just hard to stage and gauge the release point on a few chambers.
I tried two different types of .38 special ammo for this test with the same results.
I inspected and cleaned the gun as well as possible without taking the handles off to get at the insides. The gun sounds and functions fine on dry fire tests.
The Internet suggests the following possible issues and fixes:
a. Clean the living heck out of the action after taking the grips off
b. Change the weak trigger return spring

What else would you suggest?

Zastava CZ999 .40 S&W Semi-Auto:
This is a brand new gun. Grrr. (Old stock. 2013 manufacture. Gun Broker, so I doubt returnable.)
This gun is having failure to eject issues almost every time I fire it. Not stovepiping -- last shell casing wholly fails to eject from chamber, and ends up wedged in the chamber-side of the barrel when 2nd round is brought up from the magazine. (Also darn hard to get magazine to eject so I can dislodge the casing out with a cleaning rod.)
I only had one type of ammo with me (Winchester Target Ammo FMJ .40 S&W 165 grain), so I could not test if the gun likes a different ammo.
Range warden thought I might be limp-wristing. Certainly possible (I am a novice shooter, and especially inexperienced outside of revolvers) -- but I don't think this would happen nearly every time when I am being careful. (That was "fun" too -- young 20-something female range officer helping me with a bunch of male para-military, police, and active duty military male patrons standing around in camo wondering what my deal was.)
The Internet thinks possible issues include:
- Dirty gun (nope -- it was very clean)
- Worn extractor hook (it's brand new, but I have not looked at this yet)
- Extractor needs tightening or it needs new springs or it needs different springs for the ammo
- Rough feed ramp (manufacturer is excellent but known for rough finishing inside gun)
"If a spent case completely fails to be extracted from the chamber, the causes are either the extractor or the barrel throat and/or feed ramp. Extractor hooks that have been worn down from use won't be able to grab the spent case. A visual inspection will reveal if this is the cause, as the extractor hook will appear quite worn. Replacement will be warranted, though extractors are typically quite inexpensive. The extractor may also require either tightening down or may require new springs in order to function properly. The extractor should have some play, but not too much. This fix is also typically very easy and quite cheap. The other common cause of a failure to extract is a dirty or otherwise rough feed ramp. In this instance, buildup of carbon and other deposits cause the round to stick in the chamber. Likewise, a feed ramp that has been roughed up due to use can cause a round to fail to extract. You'll be able to tell which it is by a visual inspection of the barrel. In case of the former, usually a good cleaning will resolve the issue. Polishing the feed ramp can be done at home with either sandpaper or a dremel tool. You'll want to use 600 to 800 grit, but no rougher than 600. Remember that the goal is to polish the feed ramp and smooth the material, so avoid taking off too much material."

Any other ideas?

This is so frustrating after doing as much research as possible on excellent types of used guns. Do I really have to buy brand new from a store all the time?
