I have been a lurker here for some time and have gleaned all kinds of useful and quite helpful information here. Thanks to you all. I am retired Coast Guard and a current Deparment of Homeland Security consultant and have lots of experience with the 870 shot gun and Barretta 9mm, however I am a newbie when it comes to the Ruger world. Recenent causes and conditons (ie; new baby, recent breaks ins around my home) have triggerd my purchase of a Mossberg 500 for the house and with my forth coming permit I look to the venerable SP101 stainless for my person. See heres the thing, I have no experience with a revolver and have never shot one. Though, I understand profiency and practice are key, I am in somewhat uncharted waters with it and request input and suggestiongs with barrel lengths or anyother useful information. From all accounts, its durable, reliable, compact, powerful and I feel it will grow with me well.
