Will, I would like to answer that. There are several other manufacturers/importers of bad mags so I am not just picking on KKK.
It has been a mystery to me for some time as to why people will pay $500-800 for a semiauto and then put a crappy Pakki mag made over a dung fire by two guys with a hammer and some sheet steel for roofing. It is reminiscent of buying a car like a Mercedes and putting cheap tires on it! But I see it at every gun show when the "clips" guy sells bad magazines to people.
The unhappy fact of the issue is that most folks do not shoot their guns very often and when they do they tend to skimp on mags, ammo and often maintenance. I see it all the time at the range when guests show up with a poorly lubed gun, bad reloads and these type of bargain "clips". They apparently think that the gun should have stoppages during their shooting.
There are plenty of unscrupulous merchants out there who sell these abominable things as GI because they have duplicated the NSN packaging formerly used by the military. The military does not use such anymore and the stocks have long since dried up. On the M1911s I have seen in recent years, the mags were generally high quality replacements. I think the USMC specified Wilson's for their latest 1911s.
M1911s get a bad rap for a number of reasons. First, they are in fact difficult to learn to shoot in comparison to a 9mm P. Simple physics there with a 230 grain versus a 115/124 grain bullet. Next, many are fed bad ammo - the gun was originally designed to feed GI FMJ ball ammo and to make them reliable with JHPs requires some doing. Also, these guns require lubrication and maintenance as they are not Glocks. Modern polymer pistols have spoiled us in that they are nearly GI proof. Lastly, you have to use quality magazines correct for the ammo. I use GI spec CheckMates for ball and the high dollar aftermarkets (Wilson, Baer, Brown, Wolff) for JHPs.
No one ever went broke underestimating the gullibility of the American public.
Oh and I left off one other thing I see regularly. We tend to be our own gunsmiths with regard to M1911s. Maybe because there are nearly limitless accessories available, I have over the years tried to make up for my lack of skill with a technological fix. M1911s were (before CNC machining) hand fit by skilled personnel. Bolt on accessories cause lots of issues because they don't bolt on.
I no longer cut my own hair, do my own taxes and have even given up doing surgery on myself. When an issue develops, I get it addressed by someone who is demonstrably knowledgeable about the M1911. Mine now run but it has taken me since 1973 to get that figured out.
