I have not shot the G34 heavily since 2014. Mostly shoot a Stock 2. I pulled my G34 out and have playing around with it and added a tungsten guide rod, thug plug, and brass base pads. The extra weight helps the gun settle a little faster on the draw, transitions, and recoil. It also allows a little more aggression on the trigger. If I were real serious about the 34 I would get as much weight on the frame and non-reciprocating parts as possible. Trigger upgrades other than the connector don't work well for my style of shooting so I prefer a stock striker spring for a firmer reset (I use more strong hand tension than most shooters). I usually end up with a 4 pound trigger so the weight helps.
