Interesting thread. I have slammed the slide home on both military and civilian 1911's for many years and never had a problem. We used to take a pencil put in the barrel of a 1911 fire it and pull the slide back and release it and put the pencil back in the weapon and do this hundreds of times for practice and never had a problem. Of course that was with cheap military grade 1911's a $3,000.00 Kimber or other custom 1911 might not be able to handle that kind of abuse.
