Here’s a 50y target with a stock Glock and the first round was loaded via slide lock drop.
Not sure which was the first shot. I’m only seeing 9 holes so it’s mis-scored anyway. If I did load 10, I’m not sure where that 10th round went.
Regards.

I recall that @Mas has written, in a number of his articles over the years, that the hand-cycled first round can do this, and has stated that the best 3 rounds from a five round group, fired from the bench, can be generally equivalent to a group from a Ransom Rest....throwing out that first hand-cycled round and one more to account for the human factor.
I even recall a head-to-head contest with another writer using a Ranson Rest.....most likely in American Handgunner magazine. Mas' 3 round groups were damn close to the results from the Ransom.

From 2014, many of the usual suspects, and some discussion of first round:

Likes pretty much everything in every caliber.
I've not done much shooting with semi-auto pistols at distances greater than 50 yards, and none that I can recall in which I was "group shooting" at that distance. But I do remember that as far back as the mid-70's it seemed to be accepted that the first hand-cycled round from an auto pistol would likely separate from the remainder of the shots in the group.
I had a couple of 1911's in .45 ACP caliber back then that usually demonstrated that trait at ranges as close as 25 yards, and when developing handloads for those pistols, I would always shoot the first (hand cycled) round of ammo into the bern before shooting 5-shot groups.
I haven't seen that occur in multiple dozens of other pistols in the ensuing years, including 1911's in caliber .45 ACP.
I think the only proper way to test this out would be using a correctly setup ransom rest and run a couple of rounds of groups. The human factor has to be taken out.
If a pistol does seem to suffer from this effect, I think GJM has the right idea in incorporating that into your procedures. I have kinda already worked this into how I finish a range session with my carry gun. I will usually fire off the chambered hollow point round first. I then practice, at the end of practice I usually have a few rounds of HSTs that I have cycled while clearing the gun out for dryfire work previous to the range. I will usually top the magazine with those rounds, fire said rounds, and end up with a fresh round of HST cambered, then top off and proceed to carry on. Maybe a little much but I like the confidence of knowing the state of the gun and eliminating as much variables as I can.
A detail about hand cycling just occurred to me. See if you think it might matter at all.
A common method I use of hand cycling administratively on the range or loading up a pistol to carry is to lock the slide back, insert magazine then sling shot the slide back to it's farthest most extreme "range of motion" before letting it fly.
Sometimes on the range I'll insert a mag with the slide forward and just rack the slide but when shooting deliberate precision stuff I'm most often use the former method.
Think that might be closer to how the slide runs in recoil?

It was my retirement gift from all the coworkers at the PD.
Inside the box was enough cash to purchase my 870P and Colt AR from my former agency.
Plus, the department gave me my G45 duty pistol as a retirement gift. So I was blessed with quite the love offering. It made my retirement the most awesome time ever.
