Apologies if this video is old hat on here but this newbie has just discovered it and thought other newbies may like it too. Found via the NSRA web site. I now understand the whys behind some of the recommendations I received for my first target pistol.
Edit: The above link no longer points to the NSRA link but to the original from its producer, Matt, who I happily acknowledge as the creator of a very informative video.
