• Possible Downtime Alert

    I am working to migrate THR from the current cluster to a new one. I would like to get this done before the weekend, but it's unclear what the timeframe will be, as testing is still ongoing. As I am writing this the new (rebuilt) host is doing a burn-in to ensure that everything will keep running under load.

    When the migration happens users will see a Cloudflare message indicatating it cannot connect to the server. This is expected, and depending on how the migration goes this may last from 30 minutes to 3 hours - I won't know more until testing the various migration options is complete and I have finalized the plan.

    More information is available in this thread.

    As always, thanks so much for your patience.

Mec-Gar metal Glock mags

A power poster, over on the Walther board, opined that mag production was equal parts art and science. He loved MecGars.
Action Express and I have discussed the merits of metal mags and poly mag latches. He hasn't had trouble with them. I remain skeptical.
But the MecGars are great mags, and OEM in many cases.

Although MecGar has a good reputation, these magazines are unlike anything out there, so there may be issues.

Remember the Shield Arms metal magazines for Glocks? They turned out to damage magazine catches, so Shield Arms recommended to use metal aftermarket catches. MecGar side-step this problem by not punching the catch notch all the way through. Instead, it's more like a dimple. This way, its edges are smooth and do not grind the plastic of the Glock mag catch.

This is brilliant. But it offers some pitfalls. The mega-dimple may be not stamped as precisely as a conventional notch. Also, its inside may be not square enough, causing the magazines to drop. It's all in how well MecGar can execute.
 
I can see an advantage if they were producing $20 mags that would work in the Staccato P-type guns, as those mags are still in the $70 range, and I'm not sure folks have complete confidence in them even in their third generation offerings.

On the other hand, Glock mags, in their current form, are available everywhere, are very inexpensive, and have a superb functional reputation. I don't know why I'd choose anything other than a Glock mag whether it is from KCI, Magpul, Mec-Gar, or anything.
 
I really like Mec-Gar, and have many of their mags for my 1911.

This seems to be a solution in search of a problem though.

What's wrong with Glock OEM mags? Nothing! They're cheap, reliable, and plentiful. So you get an extra round with the Mec-Gar mags, so what?

I don't think that'll be enough for the majority of Glock users to switch, unless the Mec-Gar mags are cheaper than OEM mags, which I highly doubt.

I reserve the right to be wrong however...

18 rounds (which is full size gun capacity) in a compact sized gun will be a huge draw for many. I don't see people buying and hoarding as many Mec-Gar mags as they do OEM Glock mags, but I can see some people buying one, two, or 3 of them to compliment their stock Glock mags if they prove to be reliable.

They're supposed to all drop free (after gen 1 but they don't IME. That's my only gripe.
Just about all other hand and rifle platforms to ever have existed are made of metal, and they all drop free just fine provided they're designed correctly. I guess I don't understand why Glock still uses polymer on their mags at the cost of reduced capacity. If anything, they should have went with metal mags for their single stacks.
 
I bought a couple of the 18 round mags for G19. Here is one in my Ruger RXM:

Only one brief range trip so far and no issues with these in the RXM. They appear well made. They are G17 size mags with a spacer on the base plate.

Here is the MecGar spring compared to a G17 gen 5 and G17 gen 4. MecGar on the right

Ben Stoeger has reported this issue:


My use for Glock style mags are my RXM, Ruger PC Carbine and a keltec Sub 2k. I've used the Mecgars in the RXM and carbine with no problems on one range trip.
 
I'd really like them to come up with a competitor to the Shield 15 rounders that didn't require swapping the mag catch.

Frankly, I'm surprised they're not getting more than a single round from ditching the plastic outer layer of a Glock mag.

What I'd like is to see Mec-Gar make replacements for the low capacity Glocks, such as the 43, 48, and 36. That's where another round (or two) would be nice to have.

Notice that the sides are creased to hold 9mms at the right stagger angle to slide up into the center feed lips. You can't just dump rounds into any width magazine you like. I don't know where that one extra round fits in, but it isn't likely from the sheet metal tube.
 
Prices are doable at Greg Cote: Glock 17.4 and 17.5 at $22.95 versus Mec-Gar G17 at $19.95
According to Gun.Deals, several vendors are selling Glock 17 mags for $19 NIB, so I reckon they both can be found for around the same price.

Always needed a really good reason to get anything but OEM. In most cases, MecGar is OEM. Not certain what to think in this case.

A buddy fought a long battle, trying to up the capacity of his 43, rather than getting a P365. After intermittent issues, he finally foreswore his allegiance to the Big G, and got the SIG. He really tried to make the other mags (Shield?) work, and did go to a steel mag catch.
I guess I don't understand why Glock still uses polymer on their mags at the cost of reduced capacity.
One of life's great mysteries, why Glock is so wedded to their poly mags. The first ones were entirely poly, and any number of MFGs have now gone to poly (MagPul NATO, and Scorpion mags among them).
But the walls have to be thicker, which doesn't matter in exterior magazine guns. After SIG, and now Smith, have stuffed 10lbs of poo in a 7lb sack, there is a demand for more rounds in less space.
The mag lips can be an issue with all poly mags; reputedly that, or magazine bulge, is what sent Glock to their current design. CZ first generation Scorpion mags had feed lip cracking issues, and I've heard lip distortion can be a problem on first gen MagPul STNAGs.
Glock is a conservative company; having hit the original grand slam in handgun technology, they have resisted change ever since.

According to a former Glock employee I talked to at SHOT some years ago, Gaston wanted it that way, knew that they could increase capacity by going to metal mags, and was still completely unwilling to change. Maybe things will change now that he's passed--I don't know.

It's funny to think that the Glock 42, 43, and 48 would have beat the Sig P365, Hellcat, and Shield Plus to micro-compact market if they had just introduced it with a metal mags instead of polymer. They had to have lost millions in sales and counting to the competition because of that decision. Introducing a the single stack G43 with only 6+1 round capacity when all the other single stacks of that era were 7+1 or 8+1 was also mind boggling establishly since the G43 wasn't any smaller. I reckon that they are doing so well and make so much in government and law enforcement contracts to give a darn though.
