Just finished up a Glock 34 for that will be a competition gun for IDPA. The customer and I decided to add a set of Dave Sevigny Competition Sights to the gun. These sights are made by Warren Tactical and feature a plain black rear sight with a fiber optic front sight. The sight comes with a red and a green tube for you to choose. We settled on the red tube, and I think this suits my eyes better. Internally we did a competition trigger job...
