I would agree. The PT709 is small and sometimes harder to get the off hand placed squarly on the grip. But, I appreciate your video and will take a closer look at my grip and how it can be improved.
Like I said, it is also a function of hand size and gun size---and with really tiny guns, there just isn't much area to use. As such, most of the time (with tiny guns) the secondary hand just
can't be placed as high or as forward without either 1) being scarily close to the muzzle, or 2) interfering with the action of the slide.
The normal solution to this is not rotating the hand quite so far forward--you don't get as much control forward, and the amount of second-hand actually contacting the grip isn't as much (again, with a tiny grip the primary hand will cover more) but it will still work better than a teacup or thumbs locked-down grip.
I'll note: generally the gun has to be pretty small for this to be an issue. I can shoot a PF-9 normally with no problem (yes, it took some practice to get the hand placement on the PF-9, but it works, and similarly a G26 and a j-frame revolver), so for me (and I have normal-sized hands) it takes something like a Beretta Tomcat or LCP or something for it to be an issue.
And I don't carry ones
that small, because I can carry something larger which makes it much easier to shoot effectively.
It is certainly true that some of the mini-pistols out there come with their own unique issues.
