I think how a handgun fits and feels in the store has very little bearing on how well we can actually use it when making loud noises to put holes in targets. The real test is where the bullets go when pressing the trigger at the range.
A Glock feels OK to me until the timer is on, then it's all over. Literally, all over the place. Maybe left, maybe high, maybe low, occasionally to the right. First round hits on 8" plates at 12 yards? Most of the time. Consistent results across the entire rack? Not so much.
1911s generally feel a bit too big front to back for my hands, but I can stack the bullet holes on top of each other. Consistent first round hits from a holster on 8" steel plates within 25 yards? Check. Consistent results moving across multiple targets? Check.
Recently I picked up a Walther PPQ, partially due to the fact that I've always had a fondness for the P-99, and partially due to the Attorney General in the State to the South of Mine riling up the law-abiding gun owners with a unilateral announcement. (Seemed like a good time to grab another vile "High Capacity" 9mm...
) This pistol both feels great in my hands AND is as shootable for me as a 1911. At 700 rounds it's proven every bit as reliable as any Glock I've owned while being much easier to shoot consistently.
Luckily there are many different options available these days that are equally good. Contrary to marketing and popular myth, Glock is not the only option for a reliable, affordable, durable pistol. Unfortunately the best way to know how well any given pistol works for you isn't how it feels at the gun counter, but how well it works for you at the range.
