That said, it has been my experience the .40 cal Glocks are the least accurate by a wide margin.
interesting statement, what would you attribute that to?
Ron,
I am really not qualified to give an expert's assessment of why the .40s are generally less accurate, but I can say that the only truly accurate .40s I have seen have all been one off custom 1911/2011 type race guns with hand fitted barrels.
The one exception being a couple of Glock 27 sub compacts that were surprisingly accurate, but in general the G23s and G22s have been mediocre at best in the accuracy department.
Full size .40 M&Ps that I have fired have been absolutely dismal. Again though, the compact M&P .40s have been more accurate on average.
Perhaps it is that the compact barrels are more rigid. I just do not know, but the observations have been very consistent.
