A friend of mine offered me a like new Glock factory 6 inch hunting barrel for $65. I plan on shooting double tap ammo and I do not reload, should I be worried about case support? or will i be O.K.? I have been lurking her since 01' when I bought my glock 20. I just joined, I hold your opinions with the utmost respect, any advice would be greatly appreciated. Thank you, Johnny Money is an issue, I am a poor college student.
