Great decision. My first .44 was a 6" 629 that I bought brand new in 1986. I was 16 at the time, and had to have y dad do the actual buying after I saved all summer. I loved that gun but like a moron, sold it to buy a ring for a girl. I felt sick leaving the gun shop after selling it, but thought it was the thing to do. These days, I no longer have the first 629, the ring, or even the girl! After years without I replaced it with a brand new 4" 629 which I really like. Sure it has the lock, and MIM parts but after 2 trips back to S&W it's been perfect for 5 years or so? Shoots to point of aim, is very accurate, and just one of my all time favorites. I recently stumbled onto my dream gun and scooped it up...a 6" 29-2 in pristine condition. Both the 629 and 29 are great guns. In my opinion, the 29-2 is the one to look for only because, from what I understand, is the first 29 with the "endurance package" making it better able to deal with a steady diet of .44 magnum ammo. It's also the last to have recessed chambers in the cylinder, and a pinned barrel. You could argue that neither enhances the gun's performance any but their options of the past so they're nice to have in a gun. I'm not an expert but I dont recall ever seeing a 29 with full lug under the barrel. I have seen many versions of 629's with the full under lug. I know bot standard models have the lug just after the ejector rod, but I bet the weight of the full lug helps tame recoil quite a bit. Like you, I do think the N frames look better without a full lug. For a 629, try to find one before 2000 without the lock and you'll be fine. Again, this is all just my opinion...and i do HATE the lock but, mine hasn't ever created a problem. Some day if I ever have the side plate off I'll remove the lock flag just to guarantee it never locks up but honestly, at this point I have many thousands of rounds through that gun without a single issue. They dont have the nicer finish that the older Smiths has, but it makes you less weary of slapping it into a holster after firing it a bunch, laying it on the shooting table, etc. I swapped the grips with some Culina round to square butt grips and have to say, it's quite handsome. I quick word about the MIM parts these days. Metal injection technology has come a LONG way...and you just dont hear about MIM parts failing like you did 15 years ago. In a new Smith, the hammer and trigger are MIM...and they simply dont take any real abuse. A lot of 1911's these days have MIM slide release pins...now that part takes severe abuse every time the gun is fired and none of mine have ever failed...I dont recall ever hearing of one fail either, so a Smith with MIM parts is alright. If you like the gun and it's at a good price I wouldn't let that scare you away. Anyway, a nice N frame of any vintage and finish, in .44....with a few boxes of ammo and a sunny day is a recipe for a very fun day!
