New Cw45 uh oh

[Recycooler]

Hi all,Just got a new CW45 ( already owned a cw9 that was flawless)and took it to the range today,(did the Jocko prep first)first shot the front sight comes off this isnt good.

But i wanted to break it in so I decided to just point and shoot.Easy to hit a 2'x3' target at 21 ft.But it doesnt like TULAMMO steel case ammo at all,I guess you get what you pay for.14.50 box of 50 .it wouldnt even go into battery with it.I took the barrel out and tried to just drop them in,they would not go in,(My glock 36 eats this stuff up)thats a tight breach!So I went and got a box of federal from the range.This will work right?About 3 out of each mag I ran through it would not go into full battery..It took a rap of my hand to get it to go forward.I shot that box of 50,then all I had left was my winchester 230jhp's so I shot them ,as I neared the end of my ammo It seemed to clear up.I emailed Kahr about the sight but not about the other issue as I know they need a break in .Was emailing the way to do it or should I call too?I know the guys at the range would put a new sight on for free if I had it.Thanks for listening.
