Well, after waiting since last November, I got my R-9s last week and took it to the range on Sat. I had 5 boxes of 124 grain gold dots, as has been recommended numerous times on this site (I couldn't locate 115 grain). After shooting a couple mags of the gold dot, which went through without a problem, I decided to try some 115 grain Winchester "white box" that I use to practice with my Kahr PM9. I proceeded to put almost 100 rounds down the range without a misfire. I had to stop because of hand "fatigue". That is to say I was getting a little tigger "bite" and that little beauty just began generally pounding my hand. Maybe wearing a glove will help next time. I will probably limit myself to no more then 50 rounds in the future.
As I mentioned, the R-9s functioned flawlessly and loaded the first round very smoothly unlike my PM9 where many times you have to tap the slide to get it chambered. As far as accuracy, it was right on the money. At 30 feet it was shooting in the black when it was bench rested. As with most of my hand guns, the R-9s shoots better then I do.
I think the R-9s is quite an improvement over the Kahr PM9. It is balanced better, functions better and seems to be more accurate. The trigger pull is more consistent on the R-9s, although I would like to see the trigger pull be a little shorter. It conceals much better and goes quite easily in a front or back jeans pocket, using those fine holsters that R J Hedley made up for me. I think I would also like to get an IWB kydex holster, if anyone makes them.
To sum it up, I was very pleased with my new R-9s. What a great little 9mm. I am also very pleased that I can practice with the "white box" ammo. This gun is not nearly as finicky as I was led to believe, which makes it that much more of a pleasant surprise. Now if I can get over that sore hand thing all will be great.
