Hi Thank you all for your help on my other topic.I now have more questions for you very knoledgeable pepole,you have been a great help.So here goes,i was telling my brother about my recent post and my problem about a side arm.He "loaned" me a nib Colt 1991a1 i don't think he has fired more than 50 rds. through it.Don't you have to put something like 200 rds. thru a govt. model to "break it in"?Are you supposed to use FMJ or LRN?Also i have read that stock 1911's do not like hollow points.Is this so?Will the 1991 Colt feed them?Any brands you care to recomend?About stopping power didn't the .45 gain its rep as a man stopper long before hollow points were on the seen,and using FMJ right?How about LRN for defense?My brother said to use those for reliable feeding and drill a very small hole in the front of them.Won't the bullets break up if you do that?He may have been joking around to.Anyway thanks for the help guys bye.
