ksc g19 cycling problems

[takealap]

I have a not even 1 month old un custom ksc g19 with a metal slide, strengthened recoil spring, a high flow valve and ive installed a metal mag catch. Im sure you all already know, the gun doesnt cycle at all then ill take the mag out and cock the hammer back (since it stays up after I shoot it) then i'll put the mag in then it'll shoot off 2 rounds in one trigger pull. I never noticed anything with the a piece in the hammer assemblly falling off and when I first got the gun I hit the hammer up without the slide on the frame 1 time but now I only do it with the slide on. My blowback springs are kinda bent in the front and its harder to load bbs now cuz my feeding lips on the mag are kinda weird but idk what the problem could be!!!
