I went shopping for a 9mm one day. Ended up with my favorite low weigh, easy to clean... With double stack fire power and several caliber options. Glock 32, purchased 9mm (and mags) & .40 cal barrels. For the 1911 folks, look at your target and look at mine, mine has less paper to recycle
First 9? Buy something fun with other caliber options, then target your future purchases based on your experience and fancies.
