Ok, so I bought an ambidextrous safety for my Noveske 10.5". The safety switch that was in it ran smooth as silk, but this new one seems to drag quite a bit. It's far more "sticky" or rough than the original. I'm wondering if anyone has any thoughts as to why this is the case.

I've installed one before on another rifle (but didn't take the short cut I'm about to mention) with no issues and this installation went well, but I didn't have any real instructions. This time, I just released some pressure off the detent spring by partially pulling the pistol grip away from the receiver and rotating the original safety to 45 degrees and pulling it out. Then installed the ambi and snugged up the grip.

It may sound silly, but I'm just sitting here at work and wondering what the hell could be so damn different between the parts to cause this. I've only got about 15 minutes after work before I'm supposed to go run some drills with a few buddies so I thought I'd pick your brains.

1. Will the detent go completely thru the receiver if there is still spring pressure on it and the old safety is removed?
I fear if it will, I may not have heard it fall or seen anything. I've got a spare and this will be an easy fix if it's even on the radar as a possibility.

A slightly unrelated question, but I noticed this during the installation process.

2. The fire control group (tail of the trigger) seems to be just a bit off center. Is this normal or should I pull it apart before something decides it doesn't want to be there anymore?

Prior, the rifles been running like a champ, I just don't want to be damaging anything since I haven't shot it since installing the new safety and noticing the askew trigger tail.

Thanks in advance.
