Just wondering what exactly were the specs that the 1911 had to meet for the Military all those years ago??? Exact details if you can. Also i was reading through the manual of my Rock Island Armory M1911-A1FS Goverment .45 Standard Model. Never noticed this but It said the gun was designed for round nose/point ammo does that mean that Hollow Points won't feed them??? I haven't tried yet because ammo now is expensive especially .45acp HP'S. Now i did have problems with it feeding in the beginning.feeding Remington 230gr FMJ and It was impossible for it to feed Winchester white box 180gr Square Top FMJ Rounds. But then i polished up the feed ramp with some Flitz and dremel felt wheel and i was able to feed the Square tops. But just wondering any of you that own a RIA GI .45 had problems with it feeding hollow points when you first got it or no???? I always buy my Guns Brand new except for those that aren't produced anymore yes my RIA GI was bought brand new. Thanks for your help.
