HIGHLY RECOMMEND that you go to a range and rent various different pistol platforms and shoot a few rounds thru them. You may love the looks of one, but realize u have a harder time shooting it effectively compared to another model!
My first handgun was a Glock G34 mos. I was totally new to handguns, knew i wanted a 9mm and something that i could use for 3 gun. I knew that the Glocks have a good service history, are popular, common and that i liked the looks of them. So i bought one.
Took a lot of practice for me to get "OK" at shooting it. I even slapped a red dot on it to so id have less trouble pointing it accurately.
Then one day i went to an indoor range with a buddy, we rented a 1911, a Beretta 92 and a CZ shadow. I noticed right away that all of those guns fit my hands better, i could manipulate their triggers better, i found their sights better and i ultimately shoot all 3 of them noticeably better then i did with my Glock.
Sold the Glock at a loss and bought a CZ Shadow... no regrets since.
Not bashing Glocks here, i know there are people out there that prefer Glocks and are proficient at shooting them.
