The culprits were Colt Cobra, SW M38-2 and Ruger LCR - all chambered in .38 Special and in the case of the LCR, .38 Special +P. However, I don't mean to sound like a badass but I shot some +P ammo through the Colt and SW too. The Colt Cobra has an aluminum frame, as is the SW M38 while the Ruger sports a plastic frame. The Colt has factory wooden stock while the SW also sports factory rubber stock (probably Hogue) and the LCR uses the Hogue Tamer grip from the factory as well. The LCR's grip is the largest while the SW grip is the smallest and that was a major factor in shootability. The LCR and the Colt sit more solidly in the hands than the SW. I could only imagine the SW with the skinny wooden grips and how much harder it would be to shoot the gun. The sight is also where the LCR shows superiority as well. It's more prominent than the Colt and SW. The Colt is being the worst because of the heavily sloped front sight. It may look aesthetically pleasing but it glared and blurred badly with indoors light. Trigger pull...I'll have to grade the Colt the best even though the LCR is the lightest. We're talking about DA pull here because the LCR is DAO so I don't think that it was fair trying to judge the Colt and SW's SA pulls while the Ruger doesn't have that option. The LCR's pull is the lightest but it also felt unpredictable to me. Sometimes it feels like a SW pull and sometimes you can stage it like the Colt. Very disconcerting. The SW's DA pull is just stiff though smooth. The Colt's take up is smooth and light at the stacking stage but the breaking was heavy. Ammo was 130-gr ball Independence. It was tough shooting these suckers with indoors range lighting, but hey, it's a lot brighter than if you were to have to use it at home for self defense. Interestingly enough, this LCR is a lot more accurate than the other two LCRs I've rented before. It wasn't a fluke. The LCR consistently grouped much tighter than the Colt and SW, with the SW taking last in mechanical/shootability accuracy departments.
