My new carry piece Glock 21 Gen 4. I have installed Truglo Tritium nights sights, Crimson Trace grips, Ghost Edge 3.5 lbs trigger connector along with a 6 lb trigger spring, and a Glockmeister grip plug. Bought a Serpa Lvl 3 duty holster to carry it in along with a Sentry electronic card access safe to store it in.
