I carry the The USPc in .40 , 12+1
And Kmber compact in .45 7+1
There is a difference between 124 gr and 180 gr I will keep my .40
The most important factor is shot placement, The USPC platform is perfect for the round. Small enough to conceal and 13 rounds of 180 gr (pick a flavor).I think the .40 was very well designed and will be around here for a while, if not my Kimber Will do Fine.
