A tip of the hat to RWT. I emailed some questions about their tuned GSG 1911-22 and got a reply a few hours later. A follow up question was answered immediately. Encouraged by this response I ordered the gun last Friday. The transaction was confirmed right away. On Tuesday I received notice that it was shipped and it arrived on Thursday. This was getting off to a good start.
The tuned version features a trigger job and the ZR Tactical upgrade kit - guide rod, spring, plug and barrel alignment cone. It came in a hard case and the stock parts were also included (one look at that original guide rod and you know why stainless steel aftermarket versions are popular.) Overall the GSG looked well made and it looks and feels pretty much like any 1911.
I took it to the range this morning for a try out. The trigger is very nice - just the slightest hint of creep then a clean break at about 3.5 lbs. Way better than any stock GSG trigger I've tried, though they may vary since some people find them acceptable. I tested three different kinds of ammunition - CCI Blazer, CCI Minimags and Federal Auto Match. They all worked fine except for one FTE and one FTF with the Blazer. I tried the FTF round again and it still didn't go off, so it was probably defective.
The biggest surprise was the accuracy. At 15 yards I put 42 of 45 shots in a 2 inch group (standing, two handed.) The other three were close. At 25 yards, 45 of 50 rounds grouped to 4 inches. Again, the other five were still in the black 6 inch target. I found the three-dot sight easy to aim, and I usually have difficulty with iron sights. The rear sight is only drift adjustable for windage and the package includes two extra front blades for elevation adjustment. However, the sights as installed worked just fine and I didn't change anything. I don't know how this compares to a stock GSG but I suspect the alignment cone improves accuracy.
So, this was a very satisfactory dealer experience resulting in a gun that surpassed my expectations. Doesn't get much better than that.
