A friend's P07 slide will move forward from slide lock when inserting a loaded magazine (without engaging the slide release). I was told this was typical of CZ pistols. Does this same thing occur with CZ75B's?
-
Usually, It speeds up reloads, however the mag must (usually) be inserted in a very firm manner. Typically if you insert the mag somewhat gently the slide stays locked back.
I have 5 different 75 based pistols and the force required to "auto" forward the slide varies but none of them will auto forward if I don't want them to.
In USPSA I avoid going to slide lock but if I do I usually can get the slide to auto forward.

Ya ..faster to reload on transition to targets ,than slide lock.. stop …reload 😎

Wow... I never knew that and I have a mountain of cz pistols. Live and learn, huh? Now I have to try that on all of them.
Definitely works on the 75b. That one I have on me.

Works on my 75B .40.

Especially on CZ pistols but on others the “Larry Vickers Technique” is extremely helpful. Use the off hand thumb coming up after the mag load and use the slide stop. If your slide goes forward from insertion your left hand simply continues forward into position. If not you release with the left hand. No need to ever reverse direction with the support hand and slow down. Most slide releases are not positioned well so this is a good universal technique and especially useful on the CZ. Top and to the rear slows you down.

On my well-loved 75B it is much easier to do, than on the newer P01.

I don't know if you are talking about modified pistols.
My guess is the main/recoil spring is greatly overpowered. No C 75 (Type A, Type B, or Custom) should do this without some wearing of a part, or an oversprung pistol. In other words, your pistol shouldn't do this.
I'm trying to envision the wearing part.

All my P10's will auto forward with a firm reload. To get it to happen using less force is to just place your firing hand thumb on the slide lock while reloading.

I did a quick test; will the slide release when I insert the magazine with oomph.
SP01 SHADOW - NO
75 SHADOW SAO - NO
SHADOW II - YES
CAJUN SP01 - YES
CAJUN 75B - NO
75 SAO - NO
P01 - NO
PCR - NO
SP01 PHANTOM - NO
I have no idea what causes the difference but from a "feel" perspective, the "no's" feel like the magazine hits something solid, wheras the "yes's" don't.
All guns are in excellent condition and are 100% functional
Same magazine was used in each test
I did try multiple mags on the first gun, and they all had the same result
-
I had this happen just one time on a new 97b when loading it with 10 rounds in the mag. For a lot of 97's it takes way too much force to seat a mag with all 10 rounds in it. I usually just load with 9. At any rate, have any of you tried that test with less than a full load of rounds in the mag and found that it doesn't cause the slide to release?
-
Just tried it on my 1977 75 short rail. It does not work on this model.
-
It's not a matter of "model". Just as all triggers are somewhat different, so are slide releases.
Any semi-auto pistol can have a sensitive release that will respond to the motion created by inserting a magazine.
Some will jump loose, others will not.
CZ, Sig, Glock, etc are all likely to let the slide release under the right conditions.
How hard you insert the mag has more to do with it than make or model.
Click the mag in gently, and it is much less likely to release. A hard slam to seat the mag is more likely.
Is it a bad thing? If you know your gun, and always seat the mag the same way, it can save a second on reload.

Both my S2O and A-01 (which have very tight slide to rail fit) are VERY difficult to auto forward, so maybe the lack of vertical movement is the difference???
While my other pistols only have a slight vertical movement it COULD be key. Small sample size so no real conclusions, just my experience.
