The recommendation of the .22 Henry was what I was responding to.
I was responding with comments regarding a LONG GUN not a pistol, frankly for my purposes almost any long gun would be more apliccable than any pistol. Range and accuracy, being the major criteria.
I disagreed with the recommendation of the Henry based on price, and service. The need to spend over $300 on any varmint gun is not necessary. Remember in this context the gun is a "tool" not a ornament. Based on that an autoloading, Marlin, Remington, Savage and a number of other generic brands can be purchased for 1/2 the cost of the Henry. The benefit of the autoloading feature, when compared to the lever action of the Henry, specially when second shots or when facing multiple predators, can not be overestimated. No way are you going to stay on target or be prepared for a follow up shot when operating a lever gun in the same time frame as an autoloader.
My present small cal varmint gun is a JC Higgins autoloading .22 cal that is over 75 years old. It's old, it's ugly, but it's a straight shooter, and I am confident of my ability to hit with it. My large cal gun is a Russian surplus SKS, 7.62X39. It will take down anything in my part of the world, once again cheap (less than $100 when I purchased it), accurate, heavy and ugly.
In the context of the recommendation in the original post the gun we are talking about the gun being used as a tool. Now if you just like the Henry, that's a different kettle of fish.
