Guns, guitars, cars, drill presses etc... If I was issued one and had to use it, I'd teach myself to get comfortable with it. But if I'm buying one for my pleasure, I darn sure want one that I like the feel of.
My little chief's special never pointed well with it's stock little J grips. If I sighted with it and adjusted the point of aim downward, I could shoot it great. But it wouldn't point like my model 66 or my Beretta 92. I've put thousands of rounds through each. Once I built new grips for the little gun, it too pointed like the others. Now I'm back to shooting aspirins thrown in the air with my eyes closed.
Well, ok. Not really aspirins thrown in the air with my eyes closed..

But bowling pins at 10 yards by point, not aiming.
