Glock 29 Question

[MOUNTAINORACLE]

This is not a post to start a "FLAME WAR" or in no way am I slamming the Glock product. I own many different brands/makes of firearms and just like the new truck/car, firearms have warranties to fix problems that are encountered after the purchase.

I have a Glock 29 (have owned this Glock for a few years); recently I have been noticing light primer strikes. The pistol is clean and oiled correctly and this is not curd/powder fouling.

I called Glock at their customer service number and told that this pistol needs a 4256-1 trigger bar up grade to take care of the problem.

I asked Glock if I could purchase the upgrade Trigger bar and install myself. I was informed that I had to ship the pistol to Glock on my dime (they wouldn't provide a free shipping label).

The price of the part is $12.50 and I can install it myself---this cost of the shipping to Glock is 2X to 3X the price of the part.

Could some more knowledgeable members tell why:
1.) Glock didn't notify customers of the needed upgrade
2.) What exactly is difference in the stock trigger bar and 4256-1 trigger bar
3.) Why wouldn't glock cover the shipping as this would seem to me to be similar to a vehicle recall
4.) Why won't Glock ship me the part so I can install it

Thanks
