I have owned several 1100's in my life. and as long as they were clean,,they worked. In your post you say,,, dirty this and dirty that, sorry, if the gun is halfway clean it will work. I wouldn't expect any dirty gun to function for me, that is whY I clean them after use. I have shot many 1000's of shots with auto's and never had a problem. I think the problem is with those that just don't like semi's and are convinced pumps are better. I wonder why the Army, Marines etc don't have pump rifles if auto's are so inferior and prone to not working. As far as a running battle goes, what are the chances of that. Seriously, you catch a perp in your house, how many shots will it take to end it. What makes you think if you don't get the first shot off, you will get a chance at a second or a third or more shots much less a running battle. C'mon guys, this isn't a Rambo movie. If you want a pump, God bless you, but please stop knocking auto's as being useless, it simply shows your lack of knowledge about them and their dependability. A clean auto will perform every time,, period, everything else is simply BS and some kind of Macho thinking.
