Never have (yet). My MO is to first have a defined purpose for a particular firearm, then decide which platform/model fills the purpose, then research any reviews I can get my hands on, and then shop around for the best deal. Boring, I know, but it's just how my brain is wired.
Welcome to God's Country, Friend. See Gun, Buy Gun. Great huh? Of course you are free to pass out when you get the credit card bills for that gun you saw and just had to have. I am terrible about this. Impulse buy's on a Browning 1911/22. Taurus G3, CZ PO1 Omega. Ruger PCC, and yes. a CZ TS2. Blessing or a curse? MY Wife doesn't care at all.When we moved to Wisconsin from Illinois a couple of years ago I got such a kick out of being able to buy a gun and walk out of the store with it immediately I stopped at a LGS just to see what they had and walked out with a CZ TS2.
