I have looked at the Ruger Alaskan chambered .480 Ruger as a BUG in the field. While I like the Alaskan it is just physically too bulky (same frame as a .44 Mag) for my application. So, the S&W 69 would be my choice. I’ve read the 69 being built on a L-Frame stands up well to .44 recoil and is a joy to carry. A friend of mine has a pair of S&W 329’s. He’s a sheep hunter and weight is critical to him. He does shoot those 329’s year round and employs them as an EDC which is why he has two so when he sends one back to Smith & Wesson for repair he has the other. He tells me Smith & Wesson has been fantastic to work with making all repairs under warranty; the mighty .44 takes it toll on the 329 and my pal shoots full-house loads. The 329 would rank as an ultimate BUG. I think a 4 5/8” Ruger Blackhawk in .44 or .45 Colt would make an excellent compact BUG as an option.
I went with the 329 for my backcountry gun this year. Love a 44 mag and the weight of the 329 makes it a great choice. It’s a handful with full tilt loads but very manageable with reduced recoil handloads or just softer factory loadings.
