Hi Here are my top 3 I regret buying: 1. A Taurus .357 nickel plated 357 revolver. I forgot the mode number, but it was simply a metal junk after few boxes of ammo. SOLD 2. Taurus PT 24/7. Ergo wise it was good but has multiple malfunctions. SOLD 3. Eusta .32 SW. SOLD Top 3 I regret selling: 1. CZ Czechmate (actually gifted to someone totally not deserving in retrospect!). It was a top notch super accurate. 2. Stechkin - it was in very good condition with original stock. One of those days when someone convinced me to sell it to them. Was going through time when I was distracted with other things in life and the vulture got to me. 3. Desert Eagle 357 with interchangeable barrels one of them was like over 9” or so. Not practical but was great coffee table conversation- sold to a vulture What about you guys?
