I own both the LC9 and a Shield 40. The LC9 all modded out with a Galloway trigger kit, ss guiderod, low power springs, straightened trigger, trigger over travel stop, internal parts rework to eliminate stacking and smooth pull, talon grips. Shoots easy and is very accurate.
My Shield 40 has an Apex sear and blocker, Glock lower power trigger spring, trigger over travel stop, oversized grip, Talon grip. Shoots much better than the LC9 due to the much better trigger action (shorter pull, softer pull, much shorter reset). Accuracy is very good for both guns.
