1911 Magazine Analysis, Part 1 and 2

The information can be applied to almost all magazine fired weapons – not just 1911’s –

Some of you may find this interesting – others not so much ( different strokes )

PART 1 – click on the highlighted text to go to the entire article . . .


I recently got the opportunity to look at a selection of 1911 magazines. Alas, my good fortune came at another’s expense: A friend of mine noticed a burr developing in the slidelock notch of his Para-Ordnance SSP along with some wear along the front side of the slide’s slidestop cutaway after less than a thousand rounds. My friend returned the gun to Para-Ordnance for service, only to have it sent back with the burrs lightly dressed and a note saying that his warranty did not cover “normal wear,” but they would not charge return shipping “in the interests of customer service.” This is definitely not the behavior of a correctly-functioning 1911, but since help was clearly not going to come from Para-Ordnance, my opinion was requested. (Clearly an act of desparation.)

And PART 2 – again, click the highlighted text to go to the article –

The very first firearms-related article I wrote dealt with 1911 magazines. (You can find it here.) That article examined how an eclectic selection of 1911 magazines interacted with the slidelock and fed ammo.

Although the prior analysis produced several interesting discoveries, it was more survey than exhaustive analysis. The magazines were treated as entire units; though this approach was appropriate for the the questions at hand, it raised more questions than it answered. Specifically, the dramatic differences observed between magazines with tapered and straight feed lips made me wonder which part of the results could be attributed to the feed lips as opposed to the shape of the follower. Furthermore, the last analysis only looked at ball ammo; would different bullet shapes such as hollowpoints or wadcutters make a difference?

There was only one way to find out, and you’re reading its writeup.

Magazines are generally THE WEAKEST LINK – Got an issue?? Change to a different magazine – or a different brand – Generally the LAST thing you want to do is start “polishing” on the feed ramp – except maybe a “fluff and buff” using Flitz or Simichrome sparingly and a micro fiber cloth – you can totally fuck up a feed ramp if you get too aggressive – such as using a Dremel or sand paper – Go ahead, ask me how I know – LMAO!!

Have Fun – Run the Gun! – and remember – Fish Heads are Cheap!!
