i have the 40c and mine was a true p.i.t.a. to remove the first few times. one trick i read on here that helped was use the bottom of the flat mag to turn it. once it is turned, you can use the mag to push it down too.

i would like to suggest to you Products - A2 Stippling
i normally do not like stippling, but i put his number 8 design on my 40c. i feel as if there is less movement in my hand and i have noticed tighter groupings.
