Hey guys I'm in desperate need of some help with my WA SCW2 1911. It is full Metal (PGC kit) with an aftermarket steel barrel and chamber, Shooters design nozzle assembly, sheriff floating valve, steel hammer, sear and strut, 150 percent hammer and recoil springs. The problem is that when I fire the gun, the first shot blows back very weakly, then the next shot blows back hard, so every other shot is hard and all the others are pretty weak. I have no idea what to and I have a game coming up soon and this is my inly pistol I can use. Help me out guys!

that problem is typical in guns that are using green gas when they should have 134a inside. you might want to try 134a.
the other thing you should do is lube the hell out of the valve in the magazine.

Will 134 even be enough to blow back that heavy of a slide?

My Mentor Gordak is correct, Japanese guns were made for 134a.
However, the point of all those upgrades and money you have 'invested' in the weapon is to not only make it more realistic, but to enable you to use the more powerful 'green gas' or hfc22.
That being said, even when you replace the slide, the springs, the valves, etc., you will likely still experience a shorter life span on your weapon due to the increased pressures of Green Gas. Think of it like adding a intercooled turbo to your Mom's Aztec- sure, it will go faster and that's cool, but eventually it will fail and then you will still be in an Aztec....the ugliest vehicle ever made.
Back on point- I own the very same WA SCW2 M1911 with most all the same upgrades- the only thing I'm short is the metal frame, and that is where mine failed from use- the frame has a hairline crack under the thumb safety from (I believe) use of green gas. I have in fact seen a similar issue to yours on two of my other guns though: my WA SV 3.9 and my KSC USP Compact- both have the metal upgrades and both have done a very similar thing to what you described. But the issue on both of mine was twofold: 1st, the gas was cooling the surrounding metal down too fast and causing some kind of friction, and 2ndly, those alum slide aren't always made to the best specs or tolerances, so although dry and warm the actions of the guns would work freely and easily, when chilled down they would rub together causing the problem. I only use hfc134a in them now and they work flawlessly.

Right on, thanks for the info Guinness. I'll try 134 and see if that helps. One thing is that this gun apparently started as an SCW1 MEU and was later converted to scw2 with the metal kit, steel hammer, strut, and sear, and the other parts from the meu. Is it possible that an SCW1 pin could fit on an SCW2 gun and cause such problems? Cause it looks like the in is hitting a little low on the valve catching the plate under the valve and marking the very bottom of the valve instead of the center.

I think I've got it! I was messing with the magazines since all of them do it except for the original one that didnt have the valve completely screwed all the way in. The problem is that the pin wasnt hitting the valve in deep enough to compensate for the higher pressure of green. Also, the original magazine was constantly getting its mag rubbers eated by the nozzle and it turns out that the rubber was popping up each time gas came up through it and the nozzle would slam into it on its return forward.
