Request feedback on any who have had services performed by Gemini Custom Gunsmithing. http://www.geminicustoms.com/RugerGP100.html I like everything I see on their site, however, I am not sure I want to have a three inch barrel ported. I realize that muzzle flip is reduced but I'm not sure I want bullet velocity to suffer...and how 'bout the actual safety of this type of operation? Their GP100 package looks to be the perfect concealed carry weapon methinks. Again...feedback please.
