So I bought a brand new STI-LS9 off of a friend who won it at a gunshow. The gun is $725-$800 new from what I've gathered. The pricetag he had with it said the lower. I don't know ANYTHING about STI... At all. Are they reputable or did I buy myself a hi-point? (joking) It's marketed as the 'Slimmest full power 1911 on the market' Any help is appreciated. EDIT: I forgot to add. I purchased it for $300.
