Semi auto handgun jam stats- the first and last round?

I have heard that statistically, semi auto Handguns are more likely to jam on the first round or the last round in a magazine. I cannot find any data or statistics on this, and I was wondering what your experiences reflect. Thank you so much for commenting.

My guess is this is mostly outdated, and caused by poor magazine design. Probably the spring and feed lip geometry if not perfect, tension would be just right in the middle. If I recall, old 1911 magazines added a dimple on the follower to help account for lack of spring tension on the last round, as an example.
 
There are many reasons why Glock dominates the handgun market.........this article gives us a few.

From the article: "Glock also concentrated on making his weapon reliable over all else, and in a competition that allowed for twenty jams in ten thousand shots, his pistol only failed once."

Why Glock dominates the police market? because they sold 30,000 units to NYPD way back when for $75 while the rest of us were paying $400
Money talks BS walks
Are they durable and easy to tear down, rebuild, etc. like an AR? Yep - and if they fit your hand, and you shoot them well, then by all means buy a dozen of them
 
Glock Model 22 in .40 S&W.
Ok.........as I said there are solutions.

Best in your case is trade it in on a Glock 21 if you are set on bigger bullets.

If you don't mind the slightly less powerful round--the Glock 17 or Glock 19 are both fine choices.

Going to the .40 on the 9mm frame was not a good Glock decision.
 
Have never had a Glock malfunction after the first mag., and then only once or twice.

If you turn them grip up and rack the slide a bunch, it will set in the chamber block/hood interface, which can be problematic when new and sharp.
