Picked up my Shield on Sat, had a quick 20 min range session over lunch hour today. Ran 3 different brands FMJ total 100 rnds through it, no FTF or FTE. Accurate to POA but only fired at 20 ft distance. Trigger very nice IMO, smooth enough and light enough for me, would say it feels like the 6.5 lb claim. Very manageable recoil. So far, so good, no regrets over purchase at all and believe me I was pretty apprehensive about purchasing a new model/first run gun.
Side note re: safety----mine has a very positive on/off click and seems easier to disengage than engage. Can't imagine accidentally engaging in safe position and being unaware but also realize anything is possible. Have seen and heard comments that presence of safety and it not being ambidextrous is a deal breaker for some. There is a post in this sub-forum about removing safety and installing S&W plug. Might be an option to consider for those who just can't live with the safety.
Plan another range session tomorrow if time permits, will try to follow-up with another post.
