I'd consider the .44 Magnum for woods protection and hunting. Look at the two current production 629s on the right - the 4" (SKU #163603) weighs a half ounce more (41.5 oz) than the 4" GP-100, while the 6" (SKU #163606) weighs a half ounce less (45.5 oz) than the 6" GP-100. Gripped with wood, they are perfect for warmer .44 Specials - and occasional Magnums.
While that 4"-er is a great protector - and super fun with Specials - adding the Hogue/S&W .500 Magnum grips ($35 from S&W Accessories), which fit K, L, N. & X-frames, and you'll appreciate the padded backstrap - Magnums become tolerable. All recent adjustable-rear-sighted K, L, & N-frames are pre-drilled and tapped for a scope rail - just remove the rear sight (one screw). Then, with proper Weaver rings, a scope or red-dot can be mounted. Below is how my 6" 629 looks today:
Hunting .44 Magnum ammo is widely available, while decent .44 Special plinkers and self defense ammo may be a mail order item. Even making it yourself is more than .38 Specials and .357 Magnums - but, boy, are they fun! They may also be required as a minimum - even the 6" barrel length - for your local game laws. It's best to check first. Of course, the 629s are a good bit more than a GP-100 - but, they are a lifetime buy. Good luck!

PS If the .357M iswhat you want, the current GP-100s seem to be better than the last few years - and they are less expensive than S&Ws. You should be fine.
