I wanted to ask the high road masses what everyone thought on picking guns based on there caliber for purposes of just focusing on one caliber d/t such things as cost and such.Im not asking would caliber you prefer;just if when you do buy a new gun its in the same caliber as your others in your home.A friend on mine has several(7) handguns of different model and make but its always in 40SW.He obviuosly likes that caliber but we got in the discussion that although he has no problem with the 9mm or 45acp he picks the 40 for ease of purchasing more ammo.Wondering how wide spread this is.Thanks
