You are definitely correct on the grip issue and having very dry hands did not help at all. With my Glock I don't have the problem with shooting low as I do with this pistol although I've been shooting glocks for years and this is only the second time out shooting this pistol. I will be working on my grip and slowing down to improve on the accuracy. You have no idea how much I appreciate your input.LOL! Your 'eyes' comment.
Judging from the accuracy demonstrated by your bench shooting, I'm thinking you might be having a grip problem. Though you didn't have the need to re-establish your grip while shooting free-hand, you did while bench shooting. At fist glance, I was willing to pass that off as a bench shooting difficulty, but then, looking at you free hand(or off-hand) shooting with all the low hits and spread, I'm seeing a grip problem. It might just be me, but with most shots you took while standing, you physically had to bring the muzzle back down after each shot. With a proper grip, that muzzle should naturally come right back down to your point of aim, in this case, the bullseye.
Watch your red dot as you shoot. Where is it going through the shot cycle? Is the dot actually leaving the sight window? It shouldn't. You want that dot to move up and down inside the sight window in a straight vertical line. Use the dot to diagnose the problem.
At least you didn't exhibit any pre-ignition push. You weren't anticipating the recoil. Most of your low hits were somewhat centered. That's a good thing.
It is. It's also a lot of movement for me when shooting standing also. I know my poor grip did not help but I'm also thinking maybe height over bore with this pistol.That's a LOT of movement for a Nina shot from a bench rest.
Thanks. I will give both a try tomorrow.One thing I noticed is that your upper body is moving rearward with the recoil when standing. If you incorporate a slight forward upper body lean/bend and keep your core strong, it will give you a more solid platform.
As far as the hit-below-aim shots, this can be caused by tightening your grip as you shoot and/or jerking the trigger. Concentrating on each of these separately will allow you to determine if one or both are the cause.
