Like many of us short,y after I purchased my P22 (both the first and second ones) and despite my what I thought was carefully tool control my barrel wrench fell victim to the same mysterious black hole that seems to poof the occasional matching sock.

One day I noticed how similar the dimensions between the barrel nut slots and my dremmel tool collet nut were.
The measurements are: 10 mm for the barrel nut and 9.5 mm for the collet nut.
There also seems to be a $2 dollar replacement charge difference between the two with the collet nut wrench costing $2 to $2.50 and the barrel nut wrench costing roughly $4 plus a minimum of $1.50 shipping and handling.

Just an idea for anyone who has had that stupid little wrench up and poof on them.


Update: Only posted this a few moments ago but that was long enough for me to discover that one of my wonderful children has lost my dremmel tool wrench..
I love them with all of my heart but sometimes they do their best to try and drive me sane.
