Hello. Although this is my first post on this forum I have kept up with pistol-training for quite some time. I am two days and 300 rounds into the P30. Before I ask these questions I will lay out a few details. I am coming from a years work with a G19 exclusively along with it being my EDC. I am a lefty first and foremost. Although I have always enjoyed not having a slide release for my support hand to catch, is I have free range for my support hand to get really aggressive with my thumbs forward grip; I am finally opening up to the advantages of a fully ambidextrous gun. My P30 is currently v2 with a v4 conversion spring on its way.
I've noticed that I found a certain comfort over my time with the G19 gripping it in a fashion to where my middle support finger references the bottom of the trigger guard vs. using my index like the vast majority (Dave Sevigny etc...). I'm not exactly sure why I do this, I believe I found that it elevates the particular point along the frame where I can apply the most pressure when I use inward "vice-like' pressure, i.e. you feel a contraction in your pectorals. Moving to a new platform, I would like to accelerate the process of regaining proficiency as quickly as possible and the very first thing that came to me was that now I will have to avoid FTLB by making sure my support thumb is beneath the slide release. So far I have yet to experience FTLB with either grip as long as I ride my support thumb just along the bottom edge of the frame. Making light contact along the bottom edge of the rail seems to work just fine for keeping this index. This seems the case with both grips... (Index finger directly under guard or middle finger directly under trigger guard with index slightly infront of it). To clarify, I do not ride my index in front of the trigger guard at all, it just follows my middle finger directly in front of it.
I've been doing some dry firing and I can see certain consistency advantages in using my index in the trigger guard's edge like most shooters do. In trying to analyze why I feel I used the other method in the first place, I simply feel that it allows the ability to apply pressure just a hair closer to the slide vs. across the entire void of the support side grip. It also has my pinky placed in the gap of my strong hand ring and pinky vs floating along the bottom.
My question is, do I honestly need to abandon my current grip method and start using my index directly under the trigger guard?
I'm looking for a flaw and the only one I see as that due to my large hands, when I do apply inward pressure, the back of my hand has a tendency to want to pull away from the rear support side of the grip. It's as if my hand lays less "flat" into the void of the support side of the grip. The p30 also has less of a purchase area along the support side of the grip than my g19 did. Because of that, combined with the slide release dodging, I wonder if my middle finger reference grip is cramming my support hand and creating a bigger void than needed...
Any advice on any of this would be very helpful. I know that much of shooting is often charged to the "whatever your comfortable with" train of thought, but perhaps someone else has been in my position before and can chime in.
Also any advice on grip panels would be awesome. I currently run an entirely medium grip. I tried the large side panels when I took the gun out for the first 200 rounds. I have noticed any grotesque difference in anything just yet.
On another side note... During ball and dummy drills today, I noticed that during my transition from the G19 to HK I am anticipating the shot during slow deliberate shooting. I am still sort of... "staging" the trigger. Any advice on this would help as well. After much reading I am coming to find that many are having greater proficiency with a "rolling revolver" type pull. What I am asking is how I can go about training this method during dry firing and live firing? Should I avoid stopping my rearward motion at any given point during my pull at all? Basically once I begin pulling, make sure I just keep coming with increasing pressure to finish?
This brings up another question, those of you who have become proficient with this rolling trigger method, do you release to reset? or are you releasing in front of reset or all the way?
Thank you... I know this is a load of stuff...
