Dave Spaulding (& Ruger's Tactical Tips)
If you haven't had the opportunity to visit some of the training videos on the Ruger site, I think you will be pleasantly surprised. The 'tactical tips' training series is done very well.
Dave Spaulding has excellent teaching skills and is very easy to follow.
