Tokyo Marui PX4 Nightmare

It's weird indeed, the gun SHOULD have been able to take 144a as it's pretty much the weakest gas you can buy and a direct replacement for 134a which is what Marui recommend.

UK retailers have no contact with TM as a company, they buy all their stuff through Japanese wholesalers as TM do not export. The only place that realistically would have been able to help you was http://pulse-japan.jp/index.php?sl=EN unfortunately they're closing down (which is a real worry for me, since I use them to get a lot of TM spares!) so you're probably pretty stuffed for getting a replacement plastic slide new. Would be worth putting up a wanted ad on a few forums though, someone out there must have swapped out their plastic slide for a metal one and be willing to sell you their spare :)

So for a company that make supposedly the best airsoft they have zero customer services? I should have thought twice about buying it, pity as it shoots bloody amazingly!

 
They have excellent customer service if you're in Japan. But their official level of support for the rest of the world is zero, nothing, nada. The reason they're still so highly regarded is because by and large their shit doesn't need repairs.

 
I have one as well and they are lovely little guns. AFAIK the WE or (HK3) copy slide fits and is metal unlike the Marui. in fact in many ways its a better gun bar the leaky mags and its cheaper by £40. Probably your best option

Just checked, EVIKE have them at about $45, would I be able to use the TM hop unit and inner barrel?

 
Cant see why not, they are basically a copy of the Marui gun. But on your head be it!!

I tried contacting them like 4 or 5 times in the past about different things, they replied to one of them and it was that badly worded I presume they used google translate as it took a while to decipher.

Can you do me a small favour? Could you take out your hop/inner barrel and check how the nub sits in the barrel. Does the metal piece that holds it in look bent? The nub seems to stick out more to the left than be right??? I just noticed late last night, it's shooting straight up to 20 meters, haven't had a chance to test it at further distance.

Sorry mate but I have a strict policy of not fiddling or touching with my guns internals cos I know I will mess it up.

 
Well, I managed to win the metal slide :) . At the moment I don't have the gun as I sent it back to the company for inspection, can I ask has anyone else upgraded a PX4 or even another TM pistol with a metal slide? Does it badly mess up the quality of shot etc? Also, Is it possible to remove the blowback mech and hop up from the original plastic slide and drop them into the metal slide? (Therefore I won't be messing with the performance too much).

 
yeah, the internals from the plastic slide will come out no problems, does your metal slide come with a metal outer barrel too? If not, get one ASAP, the metal slide will destroy a plastic outer barrel in no time at all.

as for affecting the performance of the gun... yeah, it'll have a negative effect on blowback speed and gas efficiency, no way round it sadly, you're moving a bigger weight so it takes more energy (therefore, more gas) to do it. If you get it running really smooth you'll still be able to empty a magazine of BBs on one fill of gas, but maybe not when it's really cold.

The slide comes with a complete blowback/hop up and barrel. Frustratingly I can't try it till I get the gun back, I spoke to the company today, Hopefully this may be resolved as they agreed that the powerspray couldn't have damaged the slide, I just thought it may be an idea to utilize the strength of the metal slide with the quality of the TM internals. By using a metal slide would I not be able to use Green gas now?

 
with a metal slide you'll HAVE to use green gas/propane, abbey 144A probably won't have the grunt to cycle it properly.

 
Ah right! I take it the plastic slide is the reason that 144a is the choice gas? or is it for something internally?

 
No, just the extra weight of the metal slide, 144a isn't as powerful as green/propane (by that I mean it doesn't boil as quickly).

People tend to prefer 144a for plastic slide guns because it is weaker so won't (shouldn't ;-) ) damage the slide/frame and also because it compresses more than green or propane so you actually get more shots per mag from it.
