So many issues with semi autos not recycling and a lot of times it is a little bit of crap build up in the tube. Why the heck can't the manufacturers increase the inside diameter of the tube by a hair....literally? Why does it have to be so tight that a few molecules of crap make their gun inoperable? Don't get me wrong, I love precision in mechanical devices but what the heck, the tube just doesn't have to be that tight. No shell is going to jam if theres a hundredth of an inch of " slop" in there to compensate for a little dirt. " .....and they ask me why I drink."
