The famed 1911A1 service pistol was built to somewhat loose tolerances and famed for operability in tough conditions. Well, my first handgun was a vintage 1911 Navy. Like a typical neophyte I scrupulously cleaned and oiled it like Mr T's mini 14 on the A team.The next time I went shooting ( this was Kodiak Alaska) the piece froze mid cycle like Ivan Stavinsky- Stavir. The bemused gunner's mate tossed it in boiling water and taught me to detail strip it. Do not over oil your knife! It takes very little to attract lint and even less to properly lubricate <img src="/images/graemlins/grin.gif" alt="" />
