I have the same question that geo57 has, basically. If the OP can tell the neighbor the S&W Sport costs $550, and a Colt 6920 costs $850, he should spend the extra $300 (54.5% more than the S&W) because: . . . . . . Why?
No dust cover and Fwd Asst are important for some, and those are objective, factual differences.
Why else should he buy the Colt? Is there a proven difference in quality, accuracy, resale, or something else? Data to back that up?
My Sport has been consistently sub 1 MOA with handloads, and and although I only have about 1000 rounds through it so far, I have had NO issues of any kind (no FT Fire, FT Feed, FTE, etc.) using a very wide variety of factory and handloaded ammo. Fit and finish are great.
I have a little experience with the Colt and liked it. But I love the Sport too. Anyone out there with more experience with both?
THANKS
