Ok, here's my dilemma. A friend of mine really want's a .40 or .45 caliber polymer frame pistol. He doesn't have much money right now so he can't just go and buy one. He's been eyeing my Sigma .40 and wants to trade me his Springer Loaded 1911 with 3 clips of ammo, hard case and double mag pouch for my Sigma and some ammo. Should I go for it?
