I own .40 and .45 cal so I am not partial to either caliber..... I love them both. The EMP feels so darn good in my hand but have never shot a Defender size 1911 in .45. I hear great things about both Springfield and Kimber. The EMP is great looking but I am not a fan of Stainless. Nothing that cant be changed... My biggest hold up it the idea of buying a 1911 that is not chambered in .45. Is that weird ? I need help.... What do you guys think?
