Saw the passage below in the "CaliberCorner" forum. Hmm..M1 carbine - preferably pistolized - for house defense.Hmmm... You guys who own M1 carbines, pistolized or not - what does one in good condition cost locally ( I presume there are no "brand new" ones)? How much is the .30 M1 carbine ammo ( any JHP available?)? Have heard of mag. feed or other reliability problems - is true? Thanks. - written by ColoradoGlocker : "G21 - 4.5" barrel Speer Gold Dots HPs, 230 grn., 889 fps, 404 ft lbs muzzle energy average of 7 rounds G22 - 4.5" barrel Speer Gold Dot HPs, 180 grn., 1020 fps, 416 ft lbs muzzle energy average of 7 rounds M1 Carbine - 18" barrel Military FMJs, 110 grn., 1,999 fps, 976 ft lbs muzzle energy average of 7 rounds The .30 Carbine is considered a marginal combat weapon at ranges over 200 yds. 10 ft from the muzzle it has double the velocity and muzzle energy of my Speer Gold Dots. Looks like my carbine with a 30 rd mag is a great candidate for a home defense weapon (with either my G21 or G22 as a backup)."
