Problems inherent to compact .45 ACP pistols

Not long ago, I purchased a new Glock 30 in .45 Auto. The gun was reliable in its extraction/ejection when shooting. However, with a loaded magazine inserted, rounds could not be hand-cycled through the gun. If there was a round in the chamber and a loaded magazine inserted, the round in the chamber COULD NOT be extracted without first removing the magazine. The slide would retract approximately 2/3 the way and then stop, abruptly. It would return forward into battery without issue. Remove the magazine and the round would eject, no problem. This happened regardless of whether there were 2 cartridges in the mag, or 10. It happened with both factory mags.

After the factory plastic sight fell off, I took it to a Glock armorer and told him about the problem. He replaced the sight, put new followers and springs in my (basically new) mags, but said that it was normal for a pistol to have this problem. I put approximately 5-600 rounds through the pistol before I sold it, so it was not a "break-in" issue. I noticed the part of the slide that picks up a new cartridge from the magazine had a slight hump on it, which I theorized could be causing the slide to stick--i.e., it would retract until the hump caught on the nose of the next bullet in the magazine, at which point there was insufficient force to push all the remaining cartridges down and allow the "hump'' to clear.

I recently purchased a Springfield XD 45 Compact, which is comparable in size to the Glock 30. I wanted another compact .45, and the XD had 3 free magazines, metal sights, and conventional rifling. Magazines have adequate spring tension but are much easier to load, XD has a different extractor design, and the "pusher" part of the slide is also flat, sans hump. It seemed like the perfect answer to all the things I didn't like about the Glock.

Well, lo and behold, it does the same thing. Shoots fine but will not eject a chambered round with a loaded magazine inserted. Now, in both cases, 9mm and .40 variants of these pistols do not have the same issue. At the range, I took a friend's Glock 17, 19, and 27 and my Springfield XDM9, inserted full magazines and chambered every round, racked the slide, and ejected them in rapid succession until the magazines were empty. No problems, and all cartridges were flung clear of the ejection port.

(NOTE: I have since learned that this is not necessarily a recommended practice, even at the range, as the primer of the cartridge can potentially hit the extractor, potentially firing out of battery and igniting the cartridges below it).

Summarily, the two (very similar) compact polymer .45 Autos I've owned required removal of the magazine to clear the chamber. I care about this because if I have a light strike or a dud primer, the conventional "tap, rack" drill will not work, first requiring the removal of the magazine. This is not a quality I want to deal with in a defensive handgun, and a problem not encountered in the 9mm/.40 variants of the same design.

Is this a problem inherent to the cartridge, to the platform, or to the size of the pistol? Is this normal, and if not, can anything be done to fix it?
 
This is odd as the slide has to operate in exactly the same way when it extracts a fired case and loads the next case from the mag. You say the pistols shoot fine, but refuse to work when hand cycling the slide.

I suspect that you are simply not developing enough force when hand cycling the slide.

Just a WAG, but that 's what I have.

Good Luck,

I realize that it's hard to quantify the amount of force being used, but I'm able to apply adequate force with all other types of pistols, including those that are notoriously hard to rack, like the Kahr PM40.

Not trying to do any chest-thumping here, but I'm not small, old, or weak. I have no problem operating the slide on the aforementioned .45s, and it shouldn't take much/any additional force to eject a round from the chamber than it does to operate the slide on an empty gun, right?
 
I have had this exact problem with my Sig P220 carry. With full mag of 8 .45's, it was VERY difficult to rack. But with enough force, I could rack it.

I have a G36 that holds 6+1. With a full mag. it racks as easily as my G19.
 
The magazine spring has to be strong to stuff 10 heavy .45 cartridges into the small space and to push them up quickly enough to feed. I noticed the same phenomenon (but not to the degree) you describe, but realistically, hand cycling all the cartridges through the action is not a reasonable test of functioning (the slide moves far faster when the gun is fired than you can possibly move it with your hands), nor is it necessary in normal use.

I have a Colt Defender on my hip I just racked slide and ejected the chambered round with out any trouble with loaded mag in. Of course it only a 100 year old design so I would expect it to work . I wouldn't own one of the compact polymer .45 Autos . I keep my good reliable Colts
 
I can rack a whole magazine of live rounds out of my Glock 23. Maybe you weren't pulling it forcefully enough? My 1911's feed and extract entire rounds as well. And they have to move a .45 round a much further distance than a Glock. (Glocks have the rounds up higher and pointed into the bore better than a linked barrel 1911 style .45)

I don't recommend playing with a loaded gun. But something sounds weird. I'd like to see what your doing to cause this.
 
I didn't have that problem with my XD45, but I did the first couple of times with the Taurus PT145. With a full 10 rounds in the mag, hand cycling the gun would get the slide back 2/3 of the way. After a trip to the range and maybe 60 flawless rounds through it, I don't have a problem. I chalked it up to being a new compact 45 with stiff recoil and magazine springs.
 
Too bad, the G30SF is one of the few superb real world .45 auto's, can't imagine why you just gave up on it...

Plastic rear sight fell off and gun had occasional FTRTB issues. XD45C felt better in my hand, had metal sights, and I only lost $30 selling the Glock.


I took a video of the G30 doing this, I'll try to take a video of the XD45 and post them both for comparison.
 
I am not saying this problem isn't real, but my G30 has never had any issues with FRTB or ejecting with a loaded mag. Slide cycles fine. The only thing I noticed was my mag springs were a bit stiff, but that resolved itself with use.

Hope you get this resolved to your satisfaction. I like my G30 so much I bought a G29 as well.

Good luck
 
I have a 3.5" barrel "Officer's Model" ECS 1911 made for Charles Daly by ARMSCOR.

It was made in 2003, I bought it in 2007. I have only had trouble when the recoil springs started to go, and I called ARMSCOR to buy a replacement spring. They had changed the entire spring system since my pistol was made, and they sent me the whole new system free-they even paid for the phone call. ARMSCOR made pistols carry a lifetime warantee, even if bought used.
This pistol has never let me down other than that, and is ridiculoously accurate as well. They are sold as RIA's now that Daly is out of business.

The plastic sight fell off? Most people, and I do mean most, replace the factory plastic with NS before even taking the gun home from the shop! FTRTB? What does that signify? IMO you traded down in quality, significantly!
