I came to a realization during dry fire practice the other day why the G19's grip doesn't work for me. It's actually not that stupid hump they have put on the backstrap, it's the flatness of the grip on the left and right side. It dawned on me when I was shooting my 1911s...one of them has what's called slimline grips, they're basically very thin and very flat. The other has regular grips, which are somewhat rounded. The one with flat stocks is an expensive match grade gun that I only shoot mediocre groups with. The other one is a bottom of the barrel cheapo, but because of the rounded grips with palm swells on them, I hold that 1911 much better and shoot it much better.
I think my shooting with my G19 would be considerably better if something could be done to give the grip palm swells to either side. Does anyone make anything that might accomplish this?
