Slide Sticks when cycling AND trigger bar movement

Hello, To reduce typing and explanations I uploaded a video of my questions here: https://www.youtube.com/watch?v=4paO0wzCym8

This is a new gun manufactured January of 2015. I noticed the issue while looking into polishing the internals for a smoother trigger. A friend of mine has a shield and when comparing the take up on the trigger bar there is no side to side movement in his action.
I plan to install an APEX FSS flat trigger kit because I prefer a 1911 like trigger. I am curious if the apex kit would clean up any excessive trigger bar movement or if I need to address the movement to eliminate any additional take up it creates.

Also, if anyone has any idea as to why the slide would be hanging up I would appreciate your opinion. I have been searching but not found anything stating that this is common and solved by 1000 rounds or anything. Thanks, Matt

Private videos are useless.

Have you shot it yet?

OK. Video should be public now at https://www.youtube.com/watch?v=4paO0wzCym8

I have 200 rounds through the gun.

Comments from the peanut gallery:

My 9c sticks similar at that point while it pushes the barrel down - could be why that is one the 7 lube points. This stick is minimal and I never really noticed when racking the slide for reset.

My 9c trigger also does the move to the right. I saw a video explaining the trigger bar and why that initial move to the right happens. I don't remember the reason or know enough to provide a useful explanation.

Update

Thanks for your input guys. I spoke to Apex and they agreed that the play in the trigger bar was normal and recommended some de-horning of the trigger bar/ moving parts. When disassembling the gun for the Apex FSS Flat trigger install I noticed that there were some sharp edges on the slide where the side of the upright tab on the trigger bar rides. https://www.youtube.com/watch?v=0Fp3JTgKH-c
Wow! the apex kit is awesome. The trigger bar is held aligned with the sear with no side to side play. For a 1911 fan the flat faced trigger was the way to go! As for the 'catch' in the slide action; some sanding with 1500 grit paper rounded the sharp edge and made for a smooth action. I am very pleased with this and some trigger polishing I did. I wanted to share my results.

I do have one question: With the Apex FSS kit which trigger return spring produces a lighter pull? The white or green. From what I've researched I went for the white for about a 4# trigger pull. Thanks again.

The white will produce lighter trigger pull.

I just ordered the Apex FSS kit for my m&p9. I cant wait to install it and take it to the range. I noticed my gun has the side to side play in the trigger bar as well so hope it fixes it after the install.

thanks styner. That's what I've got in it. Weight is very close to my Kimber. For me the side to side play in the trigger bar just proved that there was more wasted movement in the stock trigger than I was after. Love the Apex. It was a fun, easy upgrade too.
