TM1911 upgrade

[yax]

I'd like to upgrade my TM 1911 to make it a top notch very reliable custom gun yet close to the original WWII appearance, I would appreciate it if you can give me some suggestions. To begin with I thought about ordering PGC metal slide and lower frame, PDI precision barrel and silver outer barrel (hopefully both steel ones ). What next? Would be nice if the gun could accept red gas(CO2?) for low temperature conditions.

if you want top-notch reliability, and want to customize it, then just swap on a PGC full metal upgrade, a enhanced recoil spring and start using propane. leave the rest stock for the best reliability. then again, don't abuse the guns.

if you want top-notch everything find every single enhanced/reinforced/power upgrade parts for it. common upgrades are high-flow valves, hammer springs etc.

for the best reliability, keep it as stock and go HFC 134A. and no don't even think about redgas... your gun will RIP before you know it....

Thanks for the answer. Is red gas really that bad for the gun(I assume red gas is plain CO2). There are ASG guns CO2 compatible, e.g. WE Hi-Capa and they seem to work reliably so is WE a lot better than custom TM ?

thats not all true. redgas isn't reliable for WE guns even if they have CO2 mags for it. there have been numerous reports about WEs breaking even in propane let alone redgas. heck even under a thousand rounds on propane your WE will start to show issues. adding to that, redgas is really hard to obtain in canada and you won't be allowed on the field with red in your gun. so just stick with your plan of a custom TM and use propane

I lack ASG experience and I will probably stick to propane, on the other hand if there are numerous reports about fullmetal WEs breaking even on propane then it suggests poor quality of these pistols in general, cannot see anything to conclude about that switching to co2 immediately killed the gun.

One more thing that bothers me, is it really necessary to install stronger recoil spring when upgrading to metal slide? I mean stronger spring makes bigger force when the slide returns to its initial position, I would rather change recoil force by regulating gas flow..

That's how much more powerful CO2 is compared to propane.

I'm not sure what you mean. Recoil and return to battery are two different forces, the former is generated by the gas and goes backwards, the latter is a reaction by the spring and goes forward. A heavier slide requires a stronger spring to return it to battery properly, period, it's not just an issue of creating a strong recoil. Again, recoil is backwards, not forwards.

If you mate a metal slide with a weak spring, there's the possibility that the spring cannot sufficiently fight the momentum of the heavy slide, causing it to not fully return the slide to its initial position. The result is your gun doesn't complete its cycle.

If you lower the gas flow, you risk not providing enough force to blow back the metal slide properly. The result is your gun doesn't complete its cycle.

I would just see if your stock recoil spring is strong enough. If it isn't, then replace it or pad it.

Thanks, I knew co2 is stronger than propane but eight times more pressure is more that I thought. Thats even more challenging to think about just plain theoretically how to use this pressure to have more shots and more stable fps (and keep it in the limits), though not sure if that can be done at all.

I though heavier slide gives it stronger recoil and stronger recoil spring is needed for faster decelerating the slide when it moves backward, now I've got this thing straightened up.
