I bought a Norinco 1911A1, received it in decent time considering the location from me. My 1911A1 unfortunately had trigger disconnect issues out of the box. Could fire two to three rounds then no trigger pull. Marstar made good on their ironclad guarantee, and had their gunsmith whip it into shape. Marstar paid for return shipping and everything. In addition whenever I called their phone, I ALWAYS received an answer. I never felt ignored or that my needs as a customer weren't met.
My 1911A1 has fired 1000+ rounds this summer without a hiccup (most those rounds Norinco too).
I will not hesitate to give these people my buisness again, customer service doesnt seem to translate to all vendors online. I also happily reccomend marstar to everyone at my gun club, most people are VERY wary about purchasing firearms from an online retailer (I have converted some of the old school members at our range!)
