Going +1 by manually feeding the chamber

Leaving the Glock loaded--yes, that's the gun in question since it is my loaded HD pistol-- is not a solution. The gun gets unloaded when it gets taken to the range, which means the previously chambered round gets ejected. I've been diligent about not re-using these rounds, so now I've got a little herd of them (well, a dozen or so) in an MTM box marked "Don't Shoot."

No cartridges are going to suffer setback from one chambering. They get thrown around both in the magazine during recoil and during normal cycling. If you're worried instead of unloading the chambered round at the range why not just shoot it? Or is that not an option at your range?
 
It should be relatively safe for any gun with a hinged/spring-loaded extractor, but its still going to be a bit harder on the part than letting the round come from the mag.

All I can do is give personal experience with a 9mm CZ 75 with a hinged spring extractor.
It WILL beak. It only took 3 rds in my 75B to weaken it sufficiently to break after about 10 shots.
The extractor is NOT movable when feeding a rd by hand. It is spring loaded to "hold" the in the case extractor groove and "at rest' is steel against steel--not against a spring. The tilt-bbl action slips the case under the extractor during normal feed. The slide will feed a rd by hand and bend the extractor face forward far enough to feed the rd, but the hardened steel is not meant to bend forward.

Other pistols I'm sure are different, but CZ 75s' extractors won't withstand this +1 hand feeding. Rds need to fed from a mag.
 
Ok, the results of my admittedly barely-scientific test. I have only four once-chambered rounds vice a dozen (the other seven rounds in the box are 9mm rounds), but that's ok. Here are the measurements in inches (these are Georgia Arms factory reloaded 180gr JHPs in mixed brass):

Rounds in the mag, never chambered:

1.1185
1.119
1.115 (not a typo)
1.1195
1.1175
1.1195
1.1185
1.118
1.120
1.119
1.118
1.120
1.118
1.1185

Once-chambered rounds:

1.1185
1.1185
1.120
1.1185

I'm not even going to calculate the variance or standard deviation. Just a quick visual of the two arrays tells me I'm not getting setback.

FST: I'm in complete agreement with you here. Clearly it's not an issue with this gun and these rounds. No, I can't carry a loaded gun onto the ranges where I shoot, even a CCW, so I have to unchamber the round.

1SOW: Thanks for sharing that. I haven't tried this with my CZs as they aren't typically serving in the HD role. Based on your post, I won't try it.

In my educated opinion, that's a design flaw...and not because it prevents single-loading.

A magazine malfunction can cause a round to be knocked into the chamber ahead of the slide...forcing either a rim snapover or an outright stoppage.
 
A design flaw, or a flawed part.

I have no experience with that sort of problem in CZs, and as a long-time (5-6 years) moderator on the CZ forum, I think I would have heard of it at least once over the years.

I don't doubt that the problem happened as 1SOW described, but wonder if it might possibly have been a defective extractor?

Maybe it IS a design flaw, but one that most folks fail to encounter -- because they don't force-feed rounds in CZs.

Whether the design is 'flawed' or the designer did what was intended, I can't say. The CZ 75 doesn't have a "pocket" for the case, the extractor design may be related to that.--I'm not smart enough to know.

If you look at the physical 75B extractor, it is a rigid non-flexible structure. The blade that seats into the case extractor groove is hardened and only thins right at the tip. It can be 'forced' to bend inward, but was not designed to do so. How many times it can withstand this is basically a matter of luck. Upon extraction, the force is against the spring while the extractor maintains it's shape.

This has been brought up and illustrated a number of times the past several years.

I witnessed a 'limited class' 1911-40 cal extractor fail in a match this past weekend. It didn't break, it weakened!. STI says to tune them at 5K. Is this too a design flaw/----hmmmm

I've loaded up my Colt Series 70 like this for YEARS.

When I worked as an investigator I made a habit of carrying the stock Colt 7 round mag loaded with an extra in the chamber and carried 2 extra Colt 8 round mags. I did that because having been in a few high stress, low thought situations I know that it's far easier to remember "Eight and out, eight and out, eight and out" than "seven and out, eight and out, eight and out." I slicked the gun up myself and being a 60s era Colt I never worried in the slightest when I loaded up, round in the chamber, letting the slide ram home before loading up the mag, every day.

I am also OCD about my carry ammo, and the only issues I had with any of my rounds was some minor scuffing on the slugs from being partially pushed into the rifling.

If you have a good extractor, it'll take the abuse for ages. When I rebuilt the Colt again this year, extractor was still tugging along like a champ.

More likely a magazine flaw causing push-feeds.

I don't remember the last time I had to retension one of my extractors, but it's been years. Up until about 2 years ago, I was burnin' a minimum of 500 rounds a week through two dedicated beaters. If I had to tune the extractors every 5,000 rounds, I think I'd be a mite upset.
