I dont know about you, but this happens at my house every time this year. We get a cool off and when it warms back up we get them all over the siding of the house
My personal opinion would be a revolver. The only reason I say that is if you never been trained over and over and then it comes to the actual defense 99%of people will forget to rack around.
I have 4 of the mobile edge and will never use them again. I have sat in the stand and watched deer walk right in front and never got a picture. I forced it to take the picture just to verify it was working.
Just like everything else...to each thier own.
