Damon, I don't mean they impacted sideways. I meant they went through the same hole or just widened the hole that was there from the last round. 
Down south we call both a sideways hit and a hit through the same hole a keyhole shot. 
ah, gotcha.  I was thinking the "sideways" deal. Thanks for the pics of the connection too BTW.  Looks like a nice setup that I... er my daughter, will need to pick up.
FWIW, I would avoid Remington Subs, they are known to be a bit dirtier than most, and are definitely louder...with some being super sonic out of my 10/22.
CCI subs have been great...at least in my guns w/ can.
I also have that tacsol extended mag release and like it.  It is a legitimate one-hander which is much better than the old flush mag release that came with my gun.  I have seen that Ruger now has their own extended mag release and I have not used one of those to be able to comment on how the tacsol may, or may not be better.  have fun!
