So much for Drastic Plastic. I was so intrigued by the looks and official Israeli military acceptance of the DEEP6COMP back strap channel insert I got one from Glockmeister. Actually I got two, one for my 17 and one for the 23. The 17 went in fine. When the time came for the 23 it was tight so I read the pamphlet and it instructed me to put pressure on the button while pushing it in. Well it went in with a snap. I thought I broke the the little tit that locks it in place, but no, the snap was my Glock 23 back strap splitting at the lanyard hole down to the end of the butt. No caution was giving in the pamphlet about the possibility of this occurring. I'm not blaming anyone but myself, however it would of been a nice idea. To say the least I am very unhappy. The gun is a newborn just picked up from the FFL one week ago. What is the deal now? Will Glock replace the receiver for me with the same serial number? Any help is appreciated. I will supply a pic when I get my camera back Thursday. I hate myself alot right now.
