Do new Glocks need time to loosen up?

[Coder]

New Glock 23 gen 4. Two questions:

1. It is pretty hard getting that last round in the mag. Normal?

2. When the mag is full, it is more difficult to fully insert the mag into the gun. Normal?

Thanks

Yes and yes. Leave the mags loaded and in a week or two and you won't have any problem.

My G30SF was particularly tight out of the box. At first, the only way I could seat a full mag was with the slide back. Somewhere after a few range sessions later, I noticed that wasn't the case anymore.

Enjoy!

Yes, that is normal.

Thanks. The universe is right again

Yes to both, and one other "it may take time" with the Gen. 4s is that, at least with the 9x19 ones, they are more susceptible to limp-wrist jams for awhile, maybe a thousand rounds or so. The dual recoil spring setup in these guns is a solution to a nonexistent problem. With a .40, it may not be much of a problem.

[glockman10mm]

Yes. And I might add that a new glock has an annoying springy sound when work the slide by hand that goes away after awhile.

after a couple range trips my mags were all loosened up.

Ok, one more observation (I assume it's normal as well), with a full mag inserted, racking the slide to chamber a round is difficult.

[glockman10mm]

Yes. More pressure against the bottom of the slide equals greater resistance.
Personaly, I never fully load my mags. I always load one less. But opinions vary.

I had similar problems with 10 round magazine on my Gen 3 G34. Not only were they hard to load, but the mags sometimes fell out of the gun when they were full and the slide was racked. Totally messed up my first USPSA match in MA when I brought brand new 10 round magazines...They are fine now though.
I never had problems on 17 round magazines, but it's possible they are using a different spring now since I know the mags themselves are different since the mag release is ambi.

I don't believe that the .40 cal gen 4s have had the same issues with limp wristing as the 9mm guns. My G23 gen 4 has eaten everythiung so far... and I've actually switched to Tula Ammo with it almost exclusively. Steel cased, but oh well... $12.50 a box and always at Walmart!

50K+ rounds through my Glock 23 and my 12 year old 10-round magazines (I bought my 23 when I lived in Jersey during the ban, and now live in NY who has their own hi-cap ban - so i've never had a full capacity G23) are STILL hard to get that last round in =)

[Rexster]

1. Yes.

2. Yes

To answer the question in the title, the pistol itself does not need to loosen up, but a few hundred rounds to verify reliability is still important. One of my G22 pistols malfed fairly regularly, about once every 100 rounds, until I put stronger springs in the magazine. Another one would lock the slide open, with rounds in the magazine, if I used 180-grain ammo. A correctable problem, of course, but I was glad to discover it on a range rather than the street.

The routine I follow is this for my G19. Lock the slide open. Insert full magazine. Rack the slide (don't use the slide lock as a slide release). Remove magazine, top off, then reinsert with authority. Seems to work well for me.

Yes and Yes, I just recently purchased a Gen4 Glock22 that I picked up on Mon.(10-11-2010). I like this weapon alot, this is my first Glock and I am very pleased with it up to this point. I have been running mainly WWB 165 grain loads through it without an issue. I have run some Federal HST 165 grain JHP also just to see how they feed,not as issue at all.
