So I want to have a 2011 high cap built but can't decide on what caliber it is going to be. I'm thinking a Infinity Ultra Match bull barrel, stainless Caspian slide, and a AllenM trigger job....but what caliber? This will be a 5" open sighted piece... No red dots or big 4" comp on the end. 38 Super? 10mm? How about a 9x25? This is not going to be a EDC piece, just for fun at the range. Any ideas?
