First off, Welcome Aboard! Sorry to see your first post is a problem. I have the G2 in 45 and love it, and hopefully can give a simple solution. In your post, I did not see you mention if you had cleaned the pistol before going to the range. All Taurus models made in Brazil (that's most of them) are PACKED with Cosmoline for the over seas trip. You have to do a DETAILED clean, not just a field strip, and that could solve most of your problems. So far as the trigger and mag release, I can tell you from my 45, it takes about 500 rounds, and lots of time with a snap cap to work things smooth. If you're not comfortable doing a detail strip, I've had good luck spraying Gun Scrubber, or other such so long as it is polymer safe. I heavily spray the GS, use a brush, wipe it clean, and spray it again. Be sure you use the little red 'straw' to get into the springs and firing pin channel, and down into the fire control group. I let it 'marinade' for a while, then wipe it clean, and spray some more. I spray it through until it runs out clear. Also, you should pull the floor plate off the mags and clean and lube inside and the spring. I hope that helps, or someone else can offer a better solution, but if all else fails you can use that Taurus Lifetime Warranty. Good luck, and keep us posted.
