Tp9SA is a great gun. Accurate, reliable, cheap, good looking gun. Bonus is you can buy Beretta 92 preban mags and dremel a magazine catch and Boom you have a 15 round mag. Thumbs up!
Or buy some pre ban Walther P99 mags and get 16+1 and dremel a notch in them. But if you can swing the extra $100 I'd get the Walther. No denying German quality when it comes to fire arms.
