OK -i have wanted to change the XPL to a XPG2 S3 or S4 for a while now,lets see what we have,
!
I want to fit the noctigon 32mm pcb with either the s3 1c or s4 2b dedomed- but it will require a couple of new mounting holes and the wires fed through one side to fit the pads. I will have to reflow the led [first time ever] using some solder paste which i will pick up tomorrow- to be cont:
We’ve got faith in you, reflowing isn’t too hard. I’ve had to do it once myself. I bet she’ll throw a good ways once your done though, can’t wait to see it.
Nice! Would love to see the success of this build 
Have faith! 
Way to go. Good luck not that you will need it.
Thanks everyone for your encouragement -i had success in reflowing the xpg2 s3 1c and it works! Now i will dedome it.
How did you manage to get the negative and positive the right way around? Even though I know which way they go for some reason I still get the occasional one around the incorrect way.
I had to double check with my magnifying lamp and then check again. Was very easy to do with the solder paste, just put it on my electric bbq plate[about 3 quarters] and thru a puff of smoke i saw the solder melt. It aligned itself perfectly , square and plumb.
This is going to be cool when it is up and running. I can not wait to see the final product.
The dedoming went well and the tint is very nice[no green]. I had to drill and tap two holes to screw down the noctigon pcb, where as the original pcb was held in place and tensioned by the reflector only.

Now what you really want to know- using 2 x imr 18350,s i measure 305 KCD and 940 lumens!!!!!! On a single AWT 18650 40a 2600 imr i get 272 KCD and 850 lumens - beamshots soon.
Nice mod looking forward to some beamshots.
I would rip out the stock driver, it sound like it is limiting performance.
And use a FET driver or a just running it straight from the battery for max performance, that is what i plan to do with a Jacob A60 mod i am doing with a XP-G2 S4 2B.
This is the first i have hear of the AWT 18650 40a 2600 battery, they must be very new, i wonder if they are VTC5 based?
Hi cajampa, this is as far as i will go with this mod and i wanted to retain all the original modes. Even on med mode it pumps out 98 kcd! Its possible the AWT cell could be a wrapped vct5, im not sure, but they really are a good cell and drive this light harder than an efest 35a 2100,s and panasonic ncr18650b,s. There is a new AWT 18650 3000mah 35a imr which looks good, just out also.
I am amazed at the output of these new xpg2 leds matched with a noctigon pcb. Here are a Jetbeam bc40[ on high] and a thrunite tn32[ set on 1132 lumen level 5] versus the M2X-ut xpg2 !

!
First is the bc40, second the tn32 third the m2x-ut, this means the olight m2x xpg2 is at least 20% brighter than my bc40 xml which i rate at least 750 otf lumens. Outdoor beamshots soon.
First up at 150 metres M2X-UT 2nd Fenix TK75 2900 
Next M2X-UT at 450 metres 
Just some quick pics- i need to get a camera tripod to get some zoomed in shots and i will find a better location.
