Here's the promised range report:
After my success with the XD Compact Tactical 460 Rowland conversion, I decided to do something more CCW-friendly...
I spoke with Johnny Rowland at the Tulsa Gun Show this past weekend. He raved over the G30 conversion he has been personally using - so I decided to go ahead and pick up a conversion kit for one. It includes the barrel, compensator and a replacement RSA.
I located a used G30 in excellent condition (CDNN currently has them for $399) and dropped in the conversion when I returned home.
Today, I had a chance to take it to the range at Nashville Armory for a test run. Pics to follow - but I gave it the same test sequence as the XD Compact Tactical. 2 rds of 45 GAP, followed by 2 rds of Blazer ball, 2 rds of Winchester Ranger T +P, 2 rds of 45 Super, and finally 2 rds of 460 Rowland - all from the same magazine.
The 45 GAP would fire but not eject - nor would the Blazer Ball. The +P, 45 Super, and 460 Rowland all fired and ejected without difficulty.
I ran a total of 50 rds of 460 Rowland through the G30 - no problems whatsoever. It does shoot with "authority" and would not be for the recoil sensitive. Even with the compensator and RSA installed - it has more recoil than my G29SF with the hottest 10mm Auto loads.
Of course, I was shooting Johnny Rowland's "personal carry" loads that have been chronographed at 1570fps from a 5" barrel for the 185 gr Nosler bullet. Even if I lose 100-150 fps from the shorter G30 - that is impressive power from a small, easily concealed handgun.
Johnny, his partner Thomas, and I were discussing the Springfield XDS - and that several of us have been running 45 Super through it unmodified. They indicated that they are planning on a 460 Rowland conversion for the XDS! Yep, you read that right... What a hand cannon that will make if it is successful.
