KJW P226 mag leaks badly/TM 1911 gas efficiency mods.

Alright, before everyone says: "GOOGLE THAT SHIT BITCH", let me explain.

KJW P226 mag leaks:
I got this P226 out of a trade. the mag leaked so badly it wouldn't hold gas even remotely at all.
I let the fill valve o'ring, the top rubber bit, and the release valve o'ring soak in silicone over night.
Now, this helped immensely, the mag now holds gas for a couple minutes, but it still leaks, i can get about 5-10 shots before the mag poops out on me.
I put the mag in water, and the leaks appear to be coming from here: 

When I got this gun, it was cobbled to shit, poor paint job(paint got on the recoil spring guide???), all i want to do is get this gun firing again.
I suppose there is something like a pin that belongs there, can anyone confirm?

TM 1911 gas efficiency:
I have a TM 1911 GOV with a guarder kit on it, and gas efficiency is pretty terrible, sometimes i can get through a mag at room temp, sometimes i cant.
I don't think it is my fill technique, as i let the mags sputter out liquid propane to be sure.
The mags don't leak, i submerged them in water and no bubbles.
I understand that the metal slide does nothing but shit on my gas efficiency. 
it has the stock recoil spring on it, would upgrading it to a 150% or 160% make a difference?
Any thing to bump mag efficiency would be nice.

Pop the pins and coat the o-ring there with white lithium grease. While you're at it, wrap the fill valve stem a couple times with teflon tape. I've done it on all three of my KJW P226 mags and none have leaked since.

As to your second question, upgrading your springs, in theory, is going to decrease your gas efficiency. The heavier recoil spring makes the slide "heavier" and the stiffer hammer spring leaves the release valve open longer. In theory, at least. Springs are cheap, test them out and see if they help. What I would do, however, is polish up the slide rails on both the slide and frame, as well as the hammer and sear mechanism. Keep the gun clean and well lubed and you should get a little snappier cycle and less resistance. That'll help with gas efficiency a bit, though whether or not it will allow you to make it through a mag every time I don't know.

Hmm, did not know those pins had o-rings, i'll have to take a look.
THe fill valve stem was already wrapped with teflon tape, i took it off and it still doesn't leak.
Also, This is the way I figure it.
The slide cycle time is long, the longer it takes the the slide to cycle, releases more gas. 
so, even though the initial cost of propane will increase, since the cycle will be quicker, it will release less unused gas.

I think Knief is referring to the o-ring at the base of the magazine, not that the pins themselves have o-rings. If there's not one there, or it's damaged, that's probably your problem.

I had the same problems in both of my KJW mags.

This fix worked great for me. Just need a tube of RTV silicon gasket maker.

Knief, i polished the slide rails on the 1911 and i am now getting atleast 1-4 extra bb's on a full propane load, thanks! I ordered a 150% spring from Airsoft Atlanta, lets see if it makes it better or worse..(I'll probably keep it on either way, the gun defineitly suffers from the stock spring on a metal slide)

Jazzman, I followed that DIY and it worked great, i didn't even think of using RTV, i had some in my garage and threw it on real quick, it worked better then teflon tape, that's for sure.

I've had great success with both mods, I will be posting a update on the 150% spring gas efficiency.
