Umarex Walther PPQ M2

I just purchased the Umarex PPQ M2. I watched many reviews beforehand which discussed the stickiness of the pellet belt, needing lubrication, etc. Any others with insights on
helping this issue? Does it loosen up with time and shooting. It's not terrible, but once in a while I have to remove the clip, then re-insert to get it moving again. I have lubed the belt with silicone. Any advice would be great.
 
I lubricated my belts with silicone. It helped but I still have had 3 belts "blow out" and become useless. This is a common problem I see all over the internet Airgun forums.
Umarex UK and Germany sell the newer, improved white nylon belts that do not have this problem. I just spoke with Umarex USA and the person there said they do not sell them, nor do they distribute to any suppliers in the USA.

Oddly if you buy the Walther PPQ M2 pellet from Pyramyd Air or Evike it pistol comes with the new, improved white nylon belt.
Improved white nylon belts, no issues, no stretch, no failures or breaks.
I have contacted a UK seller to see if they will sell to the US.

Out of a dozen AIrgun pistols, this Wlather is by far my favorite. It fits my hand well, the hard sights are accurate and powerful enough to hit targets at a distance and hit old Hot Wheels toy cars and cause some damage!!
I need 7 belts for all my magazines. If the UK seller does not ship to the USA, I do know what I will do
