I just bought a Ruger Charger. I rented a Mark IV and it was not different enough from my Ruger SR 22. The Charger is super easy to shoot accurately and it is loads of fun!This is simply my opinion, but don’t waste your time and money on Bipods, sleds and Pistol stabilizers.
Your Shield is not a target gun. So be realistic; it’s not going to do what a target gun does.
I am not expecting it to be a target gun. I do expect it to be consistent day to day. I am attempting to determine if it is an issue with my shooting abilities and/or or problems with the gun. Using these devices will help eliminate me from the equation.
How you shoot from any of those devices does not matter. What matters is how you shoot the gun in the stance you would be in, in a self defense shooting. Shoot five shot groups. Aim at the same point each time and don’t "chase" or compensate for the point of impact. If you can’t tighten the groups up to where they would be acceptable for a self defense gun; it doesn’t matter what happens with those other aid devices.
It does matter. If I cant get reasonably consistent groups when using one of those devices, it means that I am the problem.
I did not buy this gun to be only a defensive gun. A gun can be for self defense and be used for some fun at the range. As a defensive gun, I should be able to expect it to perform the same from day to day. I understand that it isn't capable of the same level of precision as a target gun. I can shoot my new Ruger Charger and my H&K VP9 with much better precision than the 9mm EZ. This tells me that I am capable of shooting accurately. Each of these guns fits and feels different and I think the VP9 ergonomics work better for me.
The EZ is primarily for my wife, who has arthritis and very weak hands. I am starting to have issues with arthritis as well and this gun may become more important to me in the future. I want to get it dialed in the best that I can so she can practice and gain confidence.
If you want to target shoot; you need a target gun. I would suggest try a 6” 686 revolver. They are highly proven performer, available all over the place, and will outshoot any of the guns we are discussing here. Or if that is too big for you, maybe a Ruger Mark IV .22. They are great for trigger time and extremely accurate.
