You chose well with a 10" bull.

They balance well, are more pleasant to shoot than the octagons for most folks, lighter/easier to carry in the field than a longer barrel, and that length is easily good enough for well beyond 100 yard deer hunting even with open sights (if you still have your eyes). If not a bright, low magnification scope will be the ticket, especially if running shots will be taken. My first choice in BG hunting handgun scopes was the 1.5-4's. In the wide open spaces of the west running shots and longer range was the norm, and they got the job done very well and more was just not needed. A favorite was the TPC's in 1.5-4 (and their 1, 2, 3, 4 or 6X). Big and bright enough with a fine dot converging tapered reticle that is good to go for target and fast target acquisition on game whether standing or running. And they hold up well to any handcannon.
The Pachy's... while I've had every factory grip set offered I think over the years (until the Contenders were discontinued), and many custom sets made for me, for spot & stock still hunting I preferred the Pachy Grippers. Mattered not whether they were the Decelerators or not even though they were a little small for my hands. I found out the hard way early on about their Presentation style grips when I got a deal on 20 sets of them unseen or tried out first. Didn't like the feel of them and couldn't get them resold fast enough. But a person with larger than normal hands may have to go to them as the Gripper is not a large grip.
Way back when I still hunted big game, I never used my 44MAG Contenders for it hardly at all even though I've had 8 3/4" and 10" octagons, 10", 14" and 15" bull Contender barrels chambered for 44MAG. What 44MAG mule deer/elk/bear/hog hunting I did was with S&W 29's and Ruger SBH's mostly, all with open sights and from 5" to 10.5" barrels (I preferred the shorter barrels though). When I did BG hunt with the Contenders I mostly used my 14"/15" JDJ and Super Bower barrels wearing scopes. They always got the nod for a hunt when I knew the area being hunted would most likely require very long shots and so scopes, and where the ability to shoot flatter and kill instantly were a huge plus.
Enough rambling... but enjoy that barrel. It's a keeper.
