glock
I'm with jmr40, and for all his stated reasons. My 629 Mtn Revolver has stayed home ever since I got the G20. The Glock also retired a 4-3/4" Blackhawk in .357 too.
For general purpose bumming, the flatter, smooither profiled, lighter G20 carries much easier. I have no worry about a large bear or mtn lion here, so the added horsepower of the .44 is not really needed. Heck, I ran the Mtn Revolver loaded down anyhow, a 240 SWC at about 1000 fps. I run the 10mm with a 180 at 1000 as well.
I've found the adjustable sights on a Smith revolver a bit irksome, having mashed the rear leaf on one, and loose screws on others. The screws loc- tited down, but the gun was done till I located another leaf. HOnestly, a service type fixed rear groove, as on the 1917's and the Model 10, the M57/.41, The Colt SAA is likely best on a rough use revolver thinks I anyhow. The target sights are pretty high profile too, and can snag and gouge, you or your gear, one needs to pay attention to holsters. So too the big hammers.
Things I like about the G20. The poly frame and what ever Glock treats the metal with are very tough, maintenance is low. Not stainless, but not a pretty N-frame blue either. I like the lanyard hole in the butt, a length of para-cord and a dog snap makes a simple rig to ensure the pistol goes where I go. No such easy arrangement on the big 'Smiths. Fiftenn cartridges in hand is comforting, but not likely needed.
Once upon a time, I could shoot the big revolvers SA very well, and would have to give a long barreled, targer sighted revolver the nod as a pure hunter.
