Hey guys. I've noticed both my Glock 29 and Glock 20 beat the crap out of my brass. And I've read a few articles where other Glock owners are having similar problems. The cuts we find in the ejector groove can shorten the life of the brass dramatically if the raised surfaces won't allow you to slide the brass into your shellholder of your press or auto primer tool. For me I can only use my brass 4 or 5 times before it will no longer fit in my Lee Auto Primer. Also, there is the issue that with all those cuts in the groove and will it decrease reliability in feeding? Has anybody figured out a way to resolve this? I've heard of people possibly filing down sharp edges on the ejector or increasing the stiffness of the recoil spring. I personally have tried a 22# spring in my Glock 20 and havn't seen any difference vs. my 17# stock? spring. I don't know. If anybody has any ideas let's hear them!
