Umarex Colt Python 6" (Polymer) Disassembly

It had to be done.

Within 24 hours of owning it, I've disassembled this one as well... (at least I've shot 1 CO2 worth of pellets/Copper BBs beforehand!).

Not a difficult gun to disassemble. Not much reason to need to opening it up either. There isn't a disassembly guide for this as far as I know. The photos are not in the order I took them, as there are points I want to illustrate which may be helpful.

Last bit of info. It is a WinGun. The mechanism is very similar to the DW715.

An overview of what you are trying to get to:



First remove the barrel shroud. The screw and pin is attached to the frame, and the shroud itself keeps the frame together also. That has to come off first.

Before you do that it would make it a bit easier if you put the mag release in the unload position. The spring will be in tension, but if it stays in that position, nothing will fly out (not an issue in this case). In the load position the spring might exert some pressure on the shroud, pushing it out. It's not a major issue either way.

The drift pin is only small, and it is a plastic polymer frame, so be careful or you will scratch it. I used a very small hex key that is just smaller than the hole, and gently push it out. No hammer required.

You can do it from left or right. Doesn't make a difference.



Then proceed to remove all the tiny screws on the frame on the right while you are there. This include the top sight screw. 4 screws on the right in total. They are all the same size except for the sight one which is long as it spans across the frame. Nothing will pop out at this stage.

Proceed to the left side of the gun. Remove the remaining small screws. 1 near the hammer, 5 under the grip cover. So 9 screws in total: 8 of the same length and 1 long one; and a drift pin!

Then you can carefully prise off the cover. Note that the trigger shoe is meant to be on the cover, and not the main frame itself. That's how they designed it (unlike the DW715 and others).



And we are back to this picture again.



The hammer is similar to the DW as well. You can just remove it without any spring problems.



Note that the hammer spring looks like the DW one... so it might break eventually like the DW one also. HeadHunter sells a replacement spring for the DW, but I don't know for sure whether it will fit this. (it should!)

Notice also that they had to put some weight it to make it heavier.



It's feather light as it is. I don't think you want to remove those. I'm sure even my 10yo can handle this revolver.

Here's a view of the hammer safety bar, common in modern revolvers. Prevents accidental discharge if the hammer drops without the trigger being pulled.



(With my Club Instructor hat on, can I presume everyone knows how to decock a revolver safely, the proper way?)

If you had read my review, you would have noticed that I thought the barrel was 6" plus a bit of cylinder long. Did I mention this was made by WinGun?



I bet the WinGun CEO has a 18" cock. FFS.

At least it's definitely rifled barrel, although the grooves aren't exactly deep. With an eye of faith you can just make out the rifling.

With the face cylinder, comes fake bullet heads.



Looks like a flat head round nose bullet. Should really be lead colour as those are normally cast bullets. Painted it "brass" anyway...



Looks a bit naff to be honest. I might paint it back to dark grey or black at a later date.

And that's it. That's a quick tour of the platymer Python.

Putting it back is the reverse of what we did, except...

The top sight.



It will be much much easier if you unscrew the sight from the bottom piece (ie. the elevation screw), Put that plate back in the frame before closing it completely.



Then screw it all back up. And you are done!

Happy to take questions!
