I just checked out the double tap ammo site and was literally amazed at some of the velocities reported. I am thinking about purchasing the 165 and 180 gr 40 s&w loads. I currently have a sig p239 and glock 22. I am not worried about using the ammo in the sig, but am kinda leery about using in the glock, although I replaced the factory barrel with a KKM. Anyone shot double tap loads through a glock? Also, has anyone tried their heavier 357 mag loads?

I've reloaded for 9mm,10mm,40,and 45ACP Glocks w/factory barrels and one with a 357 Sig Jarvis barrel with no problems.I tried some Double Tap 45ACP/230GD and got bulges almost every time.I'll not use it anymore.

Thanks for the info glockmeister. Better safe than sorry! You haven't by chance tried buffalo bore's line have you?

No,I haven't,but everything I've read about their ammo has been good.
