I've decided to undertake a new .460 Rowland conversion project since I have never been able to get the Glock conversions to run 100% with the heavy hard cast lead loads from Underwood and Double Tap. I picked up a second hand USP Tactical 45 V1 and found an extra threaded barrel and a 16x1mm LH thread compensator for an HK USP Tactical 45 pistol on Gunbroker. All the pieces are on the way.
I'm hoping that the reamer will cut the chamber on the HK barrel -- as the Germans are known for over-engineering things and may have super hardened the barrel... I was able to ream a factory USC barrel, so I am keeping my fingers crossed.
The USP Tactical pistol should be plenty strong enough to handle the pressures of the mighty .460 Rowland -- and I am hoping that stock recoil and magazine springs will run reliably, but I'll look to see if Wolf offers any extra power offerings.
The conversion should be simple -- ream the chamber to .460 Rowland specs, install the compensator and reassemble. I'll take plenty of photos of before and after -- as well as some range sessions with various loads and manufacturers of ammo over a Chrony.
I have the G30 and the G21LS in .460 Rowland, and I have previously converted a XD Tactical (premature unlocking caused bulges in the cases, so I abandoned it). In addition, I have a .460 Rowland barrel for my LAR Grizzly. I also have a carbine barrel for my USC/UMP sub gun in .460 Rowland -- so maybe I can do a little comparison to see which one gives the best velocity/power performance. I think the USP Tactical will be a winner with a great SA trigger and a 12+1 capacity. It should be a fun project.
