From round number 1 every time I fired a round the trigger would never reset and I mean every round of the 100 I shot today. I had to pull the trigger back with the end of my finger and let go so the trigger would spring forward and it would reset every time. letting the trigger forward like normal after firing a round would not reset the trigger.

So I remove the slide and everything looks normal. no excessive dirt or anything. When dry firing at the range I could pull the trigger, rack the slide, let it go like normal and the trigger would not reset. I had to let it spring forward. I finished the 100 rounds to see if anything else was going to occur but nothing did so I head to the house with my no reset issue.

On arriving home I get to the work bench and proceed to check things out. The trigger works perfectly. I'm like what the heck??? So I start thinking what could it be???

I get out the spray cleaner and spray around the trigger bar and trigger to make sure that the area is clean. The trigger gets rough and sticky. I put one drop at the trigger and at trigger bar and it operates like normal.

I put the slide back on and everything operated normally then it dawned on me that the gun was warm from sitting in the sun before I fired it at the range. So I set it in the sun outside the garage door to warm up. When warm it failed to reset every time. IT WAS MADE FOR ALASKA!

Here's what's happening. The trigger is pulled and the slide goes back, pushing down on the tab on top of the trigger bar. Then the trigger is released but when the gun is warm you can see the trigger bar is binding on something just enough to keep it from moving back up into the bottom of the slide and resetting the trigger. I could duplicate this every time. That is why letting the trigger spring forward would shock it just enough to go into place.

I checked behind the panel on the side and there was no garbage there but It was a little rough on the back. The trigger bar spring seems strong and tight enough to do the job. I ran out of sunlight (heat) and time before I could try it without the panel on. I guess i'll do that tomorrow. I was a bit hacked at first but I guess if they test fired this in the factory in air conditioning everything would have worked fine. I'm afraid if I send it back they'll try it at 72 degrees and it will work.

Recoil on the 45 was very manageable now if i can just get it reset at normal southeast summer outside temperatures (100 degrees) hopefully it will be good.

Update and problem possibly solved. Got up this morning and started first thing. Here is the series of events. I also used my CM9 for a reference of a correctly working gun.

First AM at room temp everything worked right with gun assembled. Trigger reset OK

Not enough heat outside to warm the gun so I pulled out the gun heater (wife's hair dryer) and warmed frame slightly. Trigger reset problem happened again right away.

Removed side panel and warmed the assembled gun. Trigger reset problem still occurred so it's not the side panel.

Checked frame for roughness and visible parts of trigger bar for burrs and found nothing.

Removed slide and checked cutout on the right side of slide for issues. No problem found.

I noticed that the problem was more obvious when slide was on and gun c0cked. Ahh, there was a clue. It seems that the c0cking cam must move some un-obvious amount more when c0cked than when not that way.

Started looking at the c0cking cam and trigger bar to find the binding and found that was where the problem appeared to be. It was like there was a burr or something either on the c0cking cam or the trigger bar where they meet for firing and resetting.

Couldn't see anything with the gun assembled so you guessed it. Out comes the trigger to get at the trigger bar. When I got the trigger bar out I could see that on the trigger bar where it meets the c0cking cam there was a sharp knife like edge. That was what was grabbing I was sure. Smoothed that front edge and another rough spot on the side of the trigger bar that could have been rubbing in the frame.

Put the frame back together (with side panel still off) and even dry w/ no oil or grease the trigger was smoother. Put the slide back on the frame and then warmed up the gun again. The reset seems to be working better. C0cked the gun and pulled the trigger just a tad and pushed the reset down to let the trigger bar tab and c0cking cam wear on each other a bit quite a few times to smooth it out further. Appears to be working better. The reset is much more pronounced like on my CM9 and my previous CW9.

Since I couldn't get to see Greg in AZ and heat stress test it there. I simulated outside summer conditions here and heated the gun to an uncomfortable handling temp to test it with the wife's hair dryer. Everything seems to be working now. Couldn't get to the range today but it wasn't as hot anyway. We are expecting a 97 degree day here later this week so I'll try and head to the range then to lay it in the sun and shoot it. I may be good to go. We'll see.

Summary. Tolerances are TIGHT in this gun. Not like my full size 1911 or 92FS. The frame and/or slide slightly warming was changing tolerances enough to malfunction. This would not happen at 75-80 degrees. Also there is not much polish room with the long trigger pull and long reset.

If you are of the faint of heart I don't recommend the trigger part to just anyone. I didn't think it was too bad but I have gotten myself in such a big enough mess before that this was relatively minor. I didn't even swear or anything.
