Bought mine last weekend during a big sale, I was actually there to buy 5.56 ammo. I think the store did a bait and switch with the ammo. 2000 green tips, for $449, was the best I've seen... and of course it didn't happen. They claimed the order didn't come in and course, no rain checks.
However, my wife did goad me into buying a Sport. I later discovered, she actually thought it would become hers (LMAO! Not a chance). I pick it up this Monday and already have pretty much all the upgrades I want/need.
Have Magpul MOE handguard and pistol grip. Elzetta A2 front sight tactical light mount w/ Streamlight Polytac, Vortex Strikefire... plus a couple other odds and ends.
Did a lot of homework, before I bought it. It wasn't an impulse buy, though it comes across that way... I had plans. The sale, extra money from no ammo... just sealed the deal. The Sport, repeatedly came out in top of my criteria... First and foremost, is K.I.S.S. Other things, such as; warranty, reputation, actual field reports. When I discovered, some LE departments are actually purchasing them, that was a big plus. I own an XD, which has a similar process to Melonite, that helped, since I love that gun.
No forward assist? Thank you, S&W! No dust cover? This isn't Kandahar. Besides, I don't run my guns dry.
I get more excited and firm in my belief, I bought the right gun, as the day approaches.
