Question for P226 experts: what is the difference between 9mm and 40 cal grips? Is it the distance from the backstrap to the line that connects the centers of the bolt holes or the distance from that line to the front cutoff of the grips?
The reason I am asking is that there are guns in 7.62x25 for sale around where I live, cheap, but they come with overmolded rubber grips from the factory, and it is too bulky, even for my huge hands. If I was able to slap a factory SIG plastic grip on it, it would be much handier. The only problem is that they are as scarce as rocking horse dung, and I have no opportunity to try them on, before buying either.
