What one considers a "handgun" is up to one's own interpretation. Personally, I'm not into the XP100s. They don't fit in a holster. I carry my scoped .30-30 contender in an Uncle Mike's shoulder holster. That's just ME. If I'm going to shoot a bolt gun, I'll put a stock on it and call it a rifle. Again, just ME. If I lived out in the trans Pecos and wanted to handgun hunt, I might just change my mind.
Ranges can be long out there. When I had a lease out there, I never took my Contender. In the woods here, I'll probably just hunt with my .45 Colt Blackhawk. I've already shot game with my .357, but that .45 Colt lays the whammy down by comparison, 300 grain bullet pushing just shy of 1200 fps from a 4 5/8" barrel. It's not even loaded to max, but I ain't really THAT mad at the hogs and deer around here.
I shunned Contenders until, one day, I changed my mind and decided to see what all the squawk was about. By golly, that thing has enamored me for handgun hunting, FAR superior to any caliber revolver for shooting a long way accurately. The .30-30, with a 150 Nosler, can kill 'em dead right out to 200 yards. The catch is, you have to do YOUR part. You have to have the skills to shoot that far and place the bullet where it needs to go. As I've stated, though, my longest kill was 90 yards. That was a chip shot for the Contender and the deer went down so fast, at first, I thought I'd missed! I didn't, he was piled up in the tall grass right where I'd shot, bullet just behind the shoulder.
Anyway, limit yourself with artifical biases on what a handgun is if ya want. I like my Contender a whole heck of a lot. I have a barrel in .45 Colt, too, if I want the challenge of iron sights. It's more compact than most long barreled revolvers and even lighter than many rigs I've seen. You pay for that when you pull the trigger on that thing with a hot load in it.
You can make of a Contender what you want, in a few minutes with a barrel change. I can even make a shotgun out of it. I have a .22 barrel for it that's more accurate than any rifle's I've fired, sports a 2x LER scope. The Contender/Encore system is the most versatile handgun hunting system extand IMHO. But, go ahead and knock it if ya want.
Now then, if you think the contender is a "rifle", why? Is it that it's too big to be a handgun? What do you think of a Desert Eagle? What do you think of the BFR Revolvers in .45-70 or .30-30? Those guns are bigger, bulkier, and heavier than my .45 Colt barreled Contender OR my scoped .30-30! Are THEY not handguns? Is it the superior accuracy of the Contender your problem? Hell, I'll take superior accuracy every time!
