Shooting well is a matter of training and practice, not pistol size.
True to a certain extent. But, this article is written for the prospective new gun owner. The new owner has neither training or practice yet. For me, I can shoot subcompact pistols safely and accurately enough for most self defense situations, but there is no way I can shoot a subcompact (with long and heavy trigger pull and too small to get a proper grip) as well as a full size 1911 with a good trigger.
Yup. Sadly too many buy a small cheap pistol and one box of ammo. Due to size, recoil is a killer so they only shoot one mag of ammo and shelve the gun with no training for muscle-memory gun manipulation and accuracy.
For you, I'll substitute the word "accurately" for "well." In my opinion, if you can't shoot accurately, then you can't shoot well. And, accuracy depends greatly upon sight radius.
