Well, I took the GSR out to the range today, along with my BHP (40S&W) to test loads for pinshooting. Shot the BHP first, the new load was no better than the old load. Then I shot a box of CCI brass cased 230 grain FMJ's out of the GSR. It was more accurate than the BHP with no jams.
I think the GSR is now my pinshooting pistol and the BHP is going to be for IDPA where the additional capacity is an advantage and the accuracy is adequate.
Not to mention throwing big hunks of lead downrange is FUN!
