Today's chat will be on making a factory stock gun better. Almost any factory firearm can be improved, because its built for anyone and everyone, not specific to you. Changes in grip, trigger feel, sights, etc. can really make a difference in how you shoot a particular gun because of how it fits in your hand, how you see the sights, how intuitively the trigger resets for you, etc.
I took my Gen 3 Glock 22, a gun which was issued to be my the PD and that I bought when we went to Gen 4's and had a trigger job done and installed a grip angle adapter. This is a gun that I normally shot grapefruit sized groups with at 7 yards. I shrunk it by about half with $100 in modifications.
That is a 30 round group, 29 of which are in 3.9", 24 of which are in 2.4" group. Freehand, less than half a second between shots, 3 strings of 10. The one flier is 100% my fault because I wasn't ready for how short and light the followup shot was going to be at first. This was at 7 yards at an indoor range today using American Eagle 180gr FMJ.
The head shots are with a FNS-40, which I'll do a write up on when I have more time. Same ammo, same range, etc.
..and finally, presentation drills with the P220. This is going from the low ready to firing a single shot in double action as soon as you can find the front sight. This drill is for speed, not pinpoint accuracy. My instructors will say if everything is in the "A" box, you're going to slow and need to push yourself faster because at this close of a distance you need to get rounds on target fast.
That burned up my half hour by the time I picked up all my brass, so no accuracy drill with the P220 today.
