Most folks I know personally do not have consistency between their full size, range, service pistol and their compact/carry pistol. For example I know a few guys that carry a Glock compact but their other handgun is a 1911. Most folks on gun forums say they do have consistency between their handgun combo... i.e. Glock 17 and Glock 26. I own only two handguns HK USP9f and USPc9mm. My USP9f... LOVE it. My USPc9, it's growing on me but I like it. Which is actually odd because the day I picked up my USP9f I thought "This is a ugly gun" and I was all about my USPc, but as time went on and I got to learn the guns and shoot them I just fell madly in love with my USP9f. I think I just feel more confident handling and operating a full, service size gun. Anyway I thought about adding a 3rd kid to the mix but I don't want anything smaller than my USPc9 and I'm thinking of straying from HK (Gun God's forgive me) and testing the waters. Springfield, FNP, Sig, Walther... maybe a 1911... I don't know but I was just wondering if anyone else out there mixes it up with different firearms with different manual of arms or even having your full size in a different caliber than your compact/carry gun.
