Thank you for the compliment. PSA stands for Precision Small Arms. They are (and have been for many years) the licensed manufacturer of the Baby Browning in the USA. They sell the same guns in Europe but are marked with FN's logo. They are a very small company and make a limited amount of guns per year. The company president told me that they will make about a 1000 this year. This is the ONLY gun they make, but they make a lot of different versions of them.
I have a review on the semi-auto board about this gun maker if you'd like to read a bit more.
Damn tac driver, with well over 7000 + rds through tha pipe. Bought this in spring 2011. shot a half inch one hole group at 25 yards- excluding 1 flyer( rested with a 40 dollar Nc Star scope)
