Today was the first day I could shoot at our range after I took the training class. I've shot at an indoor range and did some work yesterday at my rural property, but was mostly helping my son shoot and didn't do a lot of serious shooting myself. So, today I spent 2 hours at the range and did some serious drills on the timer.
I'm a little slower out of the holster now. That's a result of a few things, one is I'm concentrating more on my grip, so I'm thinking less about the draw stroke. As the new grip becomes more intuitive, this will be less of an issue. I've changed my draw stroke to get my left hand on the gun earlier, which results in a better grip but is slightly slower as it changes the path of the gun to be less efficient from a pure speed standpoint but lets me get on the sights faster. I'm basically relearning to draw, so while I'm not quite starting from scratch I'm close. As a result, my first shot times are about 0.1-0.2 seconds slower for "A" box hits then with my old draw.
Average first shot time:
P226: 1.69 seconds
P229: 1.71 seconds
P220: 1.76 seconds
Compare to draw and fire one shot, where I'm not thinking so much about the grip because followup shots aren't going to make recoil control an issue, I'm 0.27 seconds slower for the first shot on multistrings. I'm sure as I get it more ingrained, this quarter second will go away.
So, here's the average on my 7 yard Bill drills today (draw from the holster, fire 6 rounds) first shot to last shot:
P226: 1.69-3.63
P229: 1.71- 3.84
P220: 1.76-3.61
Now what the numbers hide on average is consistency. I started out trying a different grip (using the index finger on my off hand to hook the trigger guard and try to control recoil). The result was it was harder to keep correct lateral pressure on the heels of my palms. My P229, for example, shooting that way had end times of 4.05, 4.40, and 4.30. Shooting with the index finger under the trigger guard had end times of 3.88, 3.90, and 3.25 (getting into it) and 3.11 (too fast, strung way left, ended up putting a shot in the "C" zone, my only non A or B hit of the day. The P226 was also about .30 seconds different. I didn't try it with the P220.
When I do everything right, the results are much tighter than my groups before. I had one flier, but this is the result:
The lateral pressure on the palms of the hands has definitely tightened up my left/right spread. The trick is remembering to do it. The grip is more complicated than the 70/30 method I was using. This "crush" grip requires pulling with one hand, pushing with the other, and squeezing the palms on both. That's why my first shot is now slower but my split times are faster. I can follow the sight easier and am back on target.
Shooting my P220, every shot I strung out of the "A" zone was high. The shots looked like a zipper. I just wasn't waiting quite long enough to let the front sight settle back into the notch and shot before I had the gun completely out of recoil. In an actual shooting, not a bad thing as first shot started high in the chest and they worked into the neck or head by #6. Very little left/right movement. Even though the times may not reflect the difference, the P220 is still the gun I'm most competent with.
I'm going to send my P226 out to a well known gunsmith for a trigger job. The trigger is about 3 lbs heavier than my other Sigs, and it doesn't have the short reset trigger. I think if I can get those issues taken care of then I'll be able to shoot it as well as the P220.
In the end, when I remember to do everything he told me to do, my groups are tighter, the fliers tend to to up instead of low/left, and my split times are better. If I forget to do one part of the grip, it goes to shit and everything opens up. I've got the push/pull down because its how I learned to shoot when Weaver was the stance of the day and I fell back into it easily. The lateral pressure is still taking some time, as is the new draw stroke. All in all, the effort is paying off big, though.
