G42 - weirdness

[jh9]

FWIW, I’ve had much better luck with the newer 42s—several of them—than my original first run one, which sucked, to say the least.

I also had one of the early run 2014 42s. Still do, but used to, too. /rimshot

This was after being an early adopter of the gen4 Glocks, 2 of the 3 (17s and 19s) I eventually got running. Anyway I went through the updating parts song and dance as revision X version Y whatevers came out. Slide release, connector 6, trigger assembly housings, the works. One thing I didn't buy replacement parts for out of pocket was the barrel. The big update was in the feed ramp which I think had an outsized impact on failures to feed.

The original (note the divot in the feed ramp / chamber transition), the updated version and the one I had an (at the time) local gunsmith correct. Anyway. Mine feeds anything now.

That’s… pretty noticeable. Those first run guns were most def not ready for public consumption.

Yeah the first picture doesn't show it very well, but those are basically little m4 feedramp cuts on the sides of the ramp/throat. Which leaves a noticeable protrusion right in the middle. I think the original S&W 39s had a similar 'feature' that after causing some issue early on people asked S&W why it was there and they basically shrugged. Some sort of manufacturing artifact?

At any rate, the 2nd pic is an obvious improvement and I think that probably resolved a lot of failure to feed issues.

The 3rd pic was before they fixed the barrel and me on my 4th Glock that didn't work because of the gen4 debacle. I was ready to lead a holy inquisition to get this one sorted out. I think the discussion with the gunsmith I had was along the line of "I want a polish and throat job that is borderline pornographic." Which I got. (And works. Quite well.) But it's also the last Glock I bought (2014). I hear the 5th gens get top marks. I'll probably never know.

Not to claim any credit, but the idea originally came from Jack Weigand. Here's a link to someone quoting his deleted post on glocktalk in 2015: https://www.glocktalk.com/threads/up...#post-22518435

Rather than deal with the brain trust on glocktalk he deleted his post and moved on. I saw the post before it was deleted and emailed him from the address on his website. After a brief exchange, I took his insight to my local gunsmith where the 3rd pic above came from. Which did, in fact, work. You can get a replacement barrel from Glock now, but at the time nobody else had any answers so I went with it.

As an example, Hornady American gunner with the XTP bullet barely cycles my 42.

It is best to find the snappier ammo for function purposes also for me it is CRITICAL To have firm, locked wrists and arms for function.

Any recommendations on snappier ammo?

I've got about 500 rounds of Sergeant Major(Tula) through mine without a problem. 95 grains at 1017 FPS(advertised). It seems like it's Plus P. It's certainly P.

HST deep

Hornady CD

Aguila ball

Federal white box 95 grain ball

Underwood loaded with the XTP bullet was also good. I’m just not a fan of boutique ammunition for serious purposes.

I’m kind of new to the 42 so I’m still learning but shooting ammunition side-by-side you can definitely tell the difference between mag tech and Aguila as an example

FedEx delivered replacement 03s for all my old mags. Took Glock about 2 weeks, which was good. Now to try them out with various loads. We shall see.

My purchased a year and a half ago 42 was traded on a BG 2.0. Too many random malfunctions, most with ammunition, vertical in the ejection port and required ripping the mag to correct.

The BG 2.0 has had several malfunctions. Two or three have been a casing, stuck horizontally in the ejection port that a simple tap rack rectified. I will shoot through the remainder of my 380 ammo and then decide what to do. It’s unfortunate that no one can make a reliable 380 as they are a handy size and I do believe in many instances superior to a J frame

The G 42 had soft recoil and in general was nicer to shoot, but the BG 2.0 is a better mouse trap no question for me. I would be happy with either if they ran as good as most modern 9 mm pistols.

Just for clarity, neither of the pistols locked back on an empty magazine for me due to my thumbs forward hold, and I don’t consider that a malfunction

With hotter ammo and a firm grip They do seem to run well, but I look at these as carry guns for daughters and wives and in the fog of battle, we see how many pistols malfunction that normally don’t malfunction in the use of force thread. So a fussy pistol already starts behind the curve.

Seems like there’s a number of people that claim they’ve never had a malfunction with a G 42 but there’s also people who claim that the shield magazines work in the G 43X. But there’s also a lot to say they don’t run, to me that means it’s too much on the edge to truly trust.

Good luck with the 42’s. Was my favorite Glock to shoot

Sold my newish G42 which I had described as not reliable. Lost a few bucks on the sale obviously but that's life - about the amount of one fancy dinner for my wife and I. The store said that business for the 380s is slow as everyone wants small 9mm now. Still have some mags that I will post for sale when I get around to it.

Sigh - hope the Sig works. So far it hasn't jammed solid on the first shot, like the G42s.
