Actually bought several boxes of this without noticing that they're aluminum cases. Was a little concerned about function in my G42 since that model has been known to be a little finicky. But I burned through the first box without hesitation. I've got lots more to shoot, but so far so good! -
I have a new glock 42.seems to not like all ammo.but it dose like the Winchester 380 fmj flat nose.it ate it all with not one jam or falter.
I will be buying more.wincherster always have made good ammo in my book.. - STALEY
