Their target demographic is guys that want a 1911 that looks sharp and will maybe shoot a few thousand rounds through it. They won't be customized and they will probably never be shot enough to break one of the lesser-quality parts.<br /><br />I think the article also explains the reason why a whole pile of very good 1911 gunsmiths refuse to accept anything but Colt and Springfield pistols. It is a hassle up with which they need not have to put.<br /><br /><br /><br /><br /><br /> Just My 2¢https://www.blogger.com/profile/01870976662057532723noreply@blogger.comtag:blogger.com,1999:blog-3274583756441452923.post-73739839989951411382016-03-08T10:32:02.596-05:002016-03-08T10:32:02.596-05:00"Interchangeable" is as you know a varia..."Interchangeable" is as you know a variable term. I think Waltham pioneered the practice of having parts of known but differing values- jewels, springs, pivots etc. - at the assembly point. So if a .01 didn't fit, she'd grab a .02 and use that. I wonder if it's practical to gauge gun parts and use a similar process to make "tighter" ones.staghoundshttps://www.blogger.com/profile/05976667812875074135noreply@blogger.comtag:blogger.com,1999:blog-3274583756441452923.post-48898089482485021192016-02-20T14:41:18.362-05:002016-02-20T14:41:18.362-05:00The M1911A1 never actually got a military specific...The M1911A1 never actually got a military specification!<br /><br />There was a technical package and drawings given to any potential vendor.<br /><br />D-P-355a is as close as it gets to a milspec for it.

All guns needed to function for the lot to be accepted.<br /><br />Remington-Rand lost nearly a years production to this testing, after making guns that worked, and interchanged with each other, but did not interchange with guns made by the other manufacturers... With a war on they still rejected them!<br /><br />Today... Kimber has no incentive to interchange with Springfield. Springfield has no incentive to interchange with Colt. Colt has no incentive to interchange with Ruger. Ruger has no incentive to interchange with Smith and Wesson... and who else makes a 1911?<br /><br />I grow to pity the people who make 1911 parts and have to account for all the OEM makers differences when making parts and it's no shock that there's lots of fitting involved now. Making it so it drops into one makers gun virtually insures that it's going to be impossible to fit to another!Angus McThaghttps://www.blogger.com/profile/09295013525738248801noreply@blogger.com
