Just curious if anyone uses the pistol mag blocks in their Oly 9mm setup.  Would like to see some pics of the modified mags and hear how the setup works if anyone has any experiences with them.  Also, any problems with the magazines after they are modified to work in the 9mm AR?  Thinking about a Glock 9mm setup, but want more info before taking the plunge.

Hear a lot about the Sten and Colt mag systems, but not much on the pistol setups...  Thanks in advance for your pics and experiences.
