M69 great question, it is however like asking which cam is best on this forum! Hah! Here is my .02 worth. Please note I do not have a dog in the fight, we do not sell guns for a living. A lot of folks purchased Judges here a couple years back due to the size vs punch and flexibility with ammo. I have never heard a complaint about them and or seen a malfunction at the range, I do notice however at the range, if an individual brings one they do not shoot many rounds before they are done. They are a bit rough on wrists, by same token they are not designed for extended shooting sessions. With regard to your actual question. I would perhaps look at it a bit differently. What if you took the money you will spend on a Judge and purchased ammo for your Glock, then hit the range for more practice? Depending on who’s metric you utilize there is some deviations on distance but virtually all metrics indicate the great majority (80 plus%) of self defense incidents occur at approx seven yards. At that point you can utilize your bodies natural reaction and kinesiology to eliminate the threat. Translated distance and time dictate the need to aim. I will always aim if at all possible, but given we do not always have that luxury, exactly to your point, we must practice not aiming on occasion. You can very effectively train at home for this with your Glock, via many options. From dry fire snap caps to all kinds of laser adapters that use apps in your phone. Once your body does the repetitions you create habits and neurological pathways. This in turn negates the need to aim at some of the closer distances. Again I am a strong advocate of aiming. On the technical side at indoor distance a shotgun pattern is not nearly as big as one might suspect. Thus back to my Glock suggestion. Practice and Shoot with what ya got buddy. As much as it pains me to say this you just can’t go wrong with the Glock! Disclaimer: I do not carry or shoot Glocks thus the humor! But there is simply no getting around the fact that Glocks are reliable and accurate.
