Which airsoft gun should i by?

Should i by a kj glock 27 or a kjw m9 (silver)??? I lyk that the glock is nice nd compact but i am afraid my fingers wont fit on it.... I am only 14 but i av big enuf hands......so far i tink i am goin to by the m9 as it has a bigger magazine nd, in my opinion, it luks nicer:))
