Usually around here it's the other way around - we replace springs with brass buttons 
, but purely to boost amps. Might want to be careful about the 1/2 spring - be sure it's from a good spring.
I could be wrong in what I recall bout the pads - will check again, guess doesn't matter as long as nothing is touching them.
I purchased the SST40 version to have mounted on a rifle for hunting. The recoil will disconnect the battery with the brass button.
I used the new high current springs from Convoy
Explains that! Do you know the guy in New Zealand who had an "in" with MaxToch? I know he was big into hunting - can't recall his BLF name. MaxToch made some great lights with an emphasis on hunting. I still have a few, but dated at this point. I would think they are still around: https://maxtoch.com/c/hunting-thrower-flashlights-0377
Ah, maybe mudgripz or gadgetman, they both helped design the 2x I think. I’ve just come across them on a NZ hunting forum, never spoken to them.
Maxtoch offer some of the best hunting lights but cost a wee bit. It’s pretty hard trying to compete with my Osram C8 and L21A I sell but price wise it’s the better deal. I don’t think anyone can beat my service I provide though with lifetime labour free repairs after warranty has expired 
Yep, that's them! I was reviewing and working with Maxtoch early on as well, but they took it heavy in the hunting direction while I was more interested in general use. They seemed like nice guys, though dunno if they they were selling or not - maybe casual selling to friends, not sure. Made it seem like NZ was a land of hunters though

Huge update coming today!
Sounds interesting.
Is it the NM1 (white flat) version of the FT03 mini?
Yes, that’s correct
I hope it's customized parts like AUX board for 3535/3030 emitters, SBT90.2 MCPCB and aux board for DIY....
For the mini? Why on earth would you put a SBT90.2 in the mini
Cause there is no such thing as why not...
LOOOL
1) FT03 mini with new OSRAM colored LED options.
2) Banggood will be releasing full copper and brass version of FT03 mini (XHP50.2, SST40, and NM.1)
Full copper! 
Having Cu and Br C8 i doubt i’ll go for this monstrr heavy option again.
I’d suggest to make bare alu with copper section of driver/led/switch bulge like in MF03 mini
When will these be available? 
Under 3 weeks for preorder?
I’m new to this site. is it too late to order?
(just a white light version)
SWEET!
