@kar120c with regard to your gun not firing when the magazine is inserted before the slide is cycled, leads me to think that it is possible that your new firing pin (knocker) is 'over sized'
I usually have this problem on my 1911's (just getting into a glock now)... but with new 'upgraded'/steel knockers they are frequently too large so they can be custom fit.
The knocker - due to over sizing - may be getting caught on the magazine valve. That is why when you insert the magazine, the valve pushes up on the knocker and even when you cycle the slide there is too much upward pressure on the knocker to have it retract. Also could explain why it DOES shoot when you cycle the slide first (retracting the knocker) and then inserting the magazine since it will sit behind the knocker and not get caught on top as you insert the mag.
The problem may also persist on TM mags and not KJW mags just due to their size difference... it could be as little as a few millimetres (clones arn't always perfect)
