I purchased my first 1911 a goverment 1991a1. I intended giving it to my father who purchased and orlder style colt 22 barell and slide. I guess to make that outfit work I needed to purchase series 70 style 1911. I took the weapon to the range and I am really happy with it's performance, very accurate gun. My question is that it seems to have a lot of play or noise when I shake it side to side, espescially when the hammer is pulled back. Most of the other pistols I own are Glock and they seem to be very tight in comparison. Is this normal?
