Gun & Ammo mag just did a feature article this month testing a variety of single stack 9's. Glock 43 was one of the top finishers in a torture test of well over a thousand rounds without a single malfunction.
I probably will too, "sooner or later", although I swore I wasnt going to get a 42 either, and now have 2.Sooner or later I'll get one.
Dave, that sounds like an issue to me. An issue within 400 rounds would make me very uneasy about a carry weapon. I understand you are determined to like it because its a "Glock" but it has not proven itself until 1000 flawless rounds in my book.
The Glock 43 seemed like a good serviceable weapon, no better or worse than the shield. Certainly not a "C" notes worth better.
I do note that the 43 has one less round in the flush fit magazine. (and it only comes with one) extra magazines go for about $25. Brownells shows one with a pinky extension made by Glock, still only 6 rounds.
And the write ups in the gun rags mean nothing. These magazines do not write critically about the products their advertisers sell. Every gun is the greatest gun there ever was. Finding an article that is not a glowing report is rare.
