You need both. If you want a P7 ,get it while you can . I prefer the P7PSP for CCW over the P7M8 ,due to the heel mag release . The P7 is most likely the safest pistol ever made . You may also want to check out the H&K USP c in 45acp ,it is a larger but in the right holster it is not bad . A hard chromed P7PSP in a DelFatti IWB holster is the cats ***
