Make mine a .40 with Winchester PDX. 10+1 in an M&P compact is just the ticket for SD. 11 rounds of .40 in a smaller and lighter than any 45 package that'll only hold 7 or so rounds makes a whole lot of sense. No need to live in the past
15+1 in the FS with a 5" barrel is perfect for the house or the range. That's 2x as many rounds as a 1911.
All I know is that when I go to the range, I shoot way more 45ACP rounds than anything else.
