The Convoy M2 has always been a fair priced light with good quality. It looks as if they have a new version with a nice flat HAIII anodizing and other improvements. Rounded/softer edge on tail cap. Thick rectangular cut threads. Low resistance spring.
Sweeeet, this is going to be my next light! 
One with a 7135*8 and XML2 T6-3B will be in my future for sure.
I wonder how the driver is secured now that there isn’t a pill. Anybody know? I’m guessing a threaded retaining ring… How about driver diameter? Still 22mm using a contact board?
I think this one needs a group buy.
It loses the brass contact points on the battery tube, but looks like it gains the ability to use 20mm mcpcb's, has an integrated pill, a good set of lanyard holes, plus the changes mentioned in the first post. This is now my favorite Convoy.
I’ve already heard that the M2 is good for using protected 18650 batteries but there are quite a few of the S series that don’t. I hope in the future that they start taking this into consideration because it seems like such a simple fix to an important feature.
Both the M-2 & M-1 can be factory modded w/ high output driver and choice of emitters. I’d go the the T6-4c & 8x7135 driver.
It's probably some bean counter stupidly making the decision that shorter lights will work with 18650's, which is true, but failing to realize that many of us use longer protected 18650's because that bean counter doesn't use the product. While shorter battery tubes is rarely a problem for me, a longer battery tube wouldn't be a problem either, so it's not like they're going to lose this customer.
Btw, welcome to BLF!
Looks good, but I will wait for the host only option.
Also, 3 mm isn’t much for added flashlight length but it’s a big difference for the inside carrier depending on how the spring is set up.
Shortest are about 64.9 and the longest are over 71mm, which gets to be a lot of high resistance spring. Remember you have to consider the length along the spiral, not the length of the spring.
I was thinking the same thing!
More pictures have been added since my original post. It shows a simple brass ring holding the driver in place. Piece of cake to mod.
I wondered where the brass contact point on the battery tube went. Maybe there was never any real benefit from it and they decided to work on a better spring with less resistance. I do like the improvements to anodizing and the machining of the tail cap. This new version looks very smooth and fatter, like a roche F8. The original M2 tail was a little rough in the tail cap area which could fray the lanyard easily.
Thanks for the reply. It obviously takes a 17mm driver without a contact board but I wonder if it does except larger ones. Maybe 20 or 22mm depending on component clearance around the perimeter.
If the tube is a bit short, why not fix it by reducing the lenght of the springs to accomodate?
I wonder if anyone have the dimensions of the reflector?
How did you find this new model?
Nooooooo, not another group buy!!! I’ll feel obligated to buy one! 
It is avilable at FT now, link for DIY Host.
Wonder why this one has a brass pill, to bad.
edit:
I can see a solid base threw the reflector, chinese confusion.
FT's listing is the old M2, not the new design in the OP. FT has had the M2 host for a long time. Wonder when/if, FT will get the new one. FT is really bad with updating the product listings, so who knows...
