Picked this up on the yellow forum after a few accidents were reported with LG300s...
I think people should be aware and take precautions....I am not trying to belittle the Dominators since they have proved themselves over and over again.
This is not a new thing, I have been telling people to use protective gear allways.
Especially with Dominators.
This was posted way back on July 7th, 2004 in a well known forum:
I've been real busy, but I just finished repairing a Walther Dominator and would like to issue a safety reminder:
ALWAYS wear shooting glasses or goggles.
The rifle in question broke while a shot was being released and fast (really fast) air came at the shooter's eyes out of the barrel, becasue the gun has a rear "ramp" the air tends to get into your eye; if the shooter in question had not been using glasses, he would now wear an eye patch and be switching over to shooting from the south paw...
The culprit is a small pin that cocks the "bolt" when the side lever is brought up & back and holds the bolt in place when the side lever is brought down & fore. If it breaks, the bolt is free to slide back in its channel and while the bolt itself is pretty well contained, the air is not.
The pin is made of steel, about 3 mm's in diameter in its working section and in this particular instance, it became fatigued with use and when there was only about ½ mm left, it broke. Supposedly it is a non-stressed part as it only holds the air during the firing cycle, but reality has shown otherwise.
So, please be safe and use shooting glasses/goggles. Always.
In that particular instance I substituted a metric drill rod for the usual pin. It has not failed since.
In another instance, I substituted a metric carbide rod section (from Travers Tool Corp.) and that has not failed either.
I am somewhat dumbfounded that Walther would have elected to ignore all warnings, especially when the replacement part costs less than US$1.00, but it seems that it has done so, even in the face of clear and present danger to the users.
We are still NOT excused from using protective gear whenever we shoot, but there are grounds, IMHO to get some sort of reparation from Walther/UMAREX, as this has been a known weak point of the design.
Good luck and if I can be of any help, contact me.
