The SRH has a great trigger. The standard RH is a tough one to get a good pull as one spring does two jobs.
I hunt with my SRH and it has a 10" barrel, With a RD it is a shade over 4# then six rounds with 330 gr cast bullets needs a shoulder rig.
By the way the 240 XTP is a super accurate 44 bullet. So is the 300 gr. 296 the best powder. Use a federal 150 primer, believe me, mag primers will triple groups.
I don't believe barrel length is real important in a great caliber like the .44. Get what you like. I like long to get the muzzle blast away more. All you need is room to consume all the powder and NO, it is not gone in an inch.
