Cooled P226 Sneak Peek

Hey guys and gals.

With all the talk recently about overheating SIG P226s and 229s and their associated problems, I decided to put my mind to it and see if I could come up with a solution. This is a preview of my design for a fluid cooled stainless 226 slide.

First I needed a place to mount the reservoir, so I picked up one of these for cheap from a paintball shop:

Then, I needed a reservoir, so I picked up one of these r/c fuel tanks (500 mL):

Along with some silicone tubing and brass tubing for where it enters the slide.

Now, I needed a way to move fluid, so I went back to the r/c people for a smoke fluid pump:

A few inlets and outlets on the slide (I'm thinking shooter's left for in and right for out):
And this is how it will all go together:
What do you think? I'm hoping I can get a fairly high flow through there, as the brass I'm using inside the slide should be kink-free if I bend it right, but does anyone have a suggestion for a non-flammable coolant that is more efficient than water?

That is pretty ingenious and should reduce the failure rate. Aluminum fins on the side of that reservoir might help balance it a bit and accelerate the cooling. Can't wait to see how it affects accuracy as consistent temp will reduce the cold bore/ hot bore differential.

It's a very common problem. But only the the US made ones. It's because when they make them they, they,..., THEY put some polymer in the metal to make it cheaper!! And, and,.. AND they make them thinner also!!! Huhum K? And, and, they use...gulp...mim parts!!!!!!!!!!!111!!1oneone1!! And they suck too.

Never seen a German one overheat. Have you? No? Case closed!! German SIG are good US ones suck.

If you read it on the internet, it must be true! :bangHead:

I hope your joking lol

polymer in the metal???? what? do you mean the guide rod?

MIMs parts have not failed in all the one's that I insp.

Also what part is thinner?

I totally neglected heatsinks. (See, that's a big reason I posted, in case I missed something like that!) I added them to the picture, not so that I can awe you with my artistic skills, but more so I don't forget later!

Dear Dsiwy,

this is a friendly reminder that your sarcasm sensor has run for 3463 post since your last check-up. As you know our experts estimate the life of your sensor to 3000 posts. As such we would request you to have it checked out as soon as possible by your nearest OldFrankHog dealer.

Your's in heart and soul, wishing you well, hoping for the best, dreaming of your long....well, anyways have a nice day!

Just checked and it is worn out "It just needs a release of my fuilds ;)"

ahhhhh internet #### there you are
 
acm, I think you have far too much spare time on your hands!!!

Nice "concept" design.
However, I think you've got it all wrong. Too many moving parts in that design, besides, the water will eventually 'come to a boil' due to the ultra high heat input.

The shooter will still get his hands over heated, perhaps burnt from steam, or scalding hot, boiling water!

I'd suggest you consider revising the design. Perhaps look at using some form of cyro cooling. Maybe dry ice, or.............................hmmm, I'm thinking a small wrist, or belt mounted high pressure C02 tank. Using a 1/8" s.s braided line to feed a spray system that could constantly fog the slide with C02.

Less moving parts, constant cold cooling source.........................I'm liking this idea even more!

Have a good evening guys. I've got some steaks to BBQ up.

Nice set up but you could just pee on it every mag change and not worry about the added weight.

Hey, we missed April 1st by two weeks!

I see what you're saying. Let me ask you this, because it applies either way... Should the inlets & outlets all be on one side, or alternated... Here, like this:
