Hello everyone. I want to thank you all in advance. I'm looking at getting a sig 228 cpo. I really like the one that my local dealer has and I really need some advice on purchasing a used firearm. My only hangup is the price that i'm not so sure about and wanted to make sure i was making the right decision. It's 699. The reason I ask is that I can get a new M11a1 for 900. From what I've researched(google) I notice that there is a weight difference of 5 ounces being that the 228 is lighter. Although the m11a1 comes with all the bells and whistles. So basically I really need to get some advice on the price since it comes from Sig with a 1 year warranty. Oh yeah i need to make my mind up by Tuesday.
