Thinking about taking back my brand new XDM-40 never shot before to trade for XDM-45. Any advice? Im only losing 3 rounds but gaining a good caliber if I go for the .45 Both calibers are the exact price so I wouldnt lose anything besides the 10% restocking fee. Sucks because I bought a bunch of .40 rounds ordered some X-treme grips but still thinking about returning. Purchased the handgun on Sep 2, 2011 only have 30 days to return or trade, any advice would be appreciated. Thanks!
