I honestly don't know if I knew they made a glass strikers. After a quick google search I found this. I have no idea about the quality of this one but I have ordered from the company before. They may be other brands on the site too. http://www.midwestturkeycall.com/detail ... dn=1&link=
Everybody always digs on how shotty primos slates are, but every time I have had issues with a bird it seems like I can always pick this call up and get him going. I own a couple high dollar slates and I rarely even carry em cause ive had so much more success with this call.
