personally i have never owned a Glock, but have shot many of them over the years. i have just found other pistols that fit my hand better, so i have never owned one. would i buy a Glock? it depends on if the right one comes along at the right time and price. they are a reliable pistol that does what a pistol is suppose to do. and i will say this, my first love of pistols is and will always be 1911's, but i own other pistols for different reasons also.
best advice is, try one out and see if it suits you. if it doesn't fit your hand well, then there are probably better choices than the Glock. try out several different brands of pistols. buy the one that fits you well. the better the pistol fits you, the better a shooter you can be.
