UPDATE: Hello, Decided to post this seperate anyway rather than leave it attached to the Boberg XR9-S post. I went to the range today with my Boberg XR9-S & my Kahr PM9 as these pistols are very similar in size. The perpose was to do some tests with my cronograph. These will not be actual dimentions but they are what I get with my calipers.
Kahr; width, .893" (without slide lever-lock) width .980" (with lever).
Boberg; width, .960". (lever is within the frame width)
Kahr; height, 4.200" (includes sights).
Boberg; height, 4.240" (includes sights).
Kahr; lenght, 5.530".
Boberg; lenght, 5.110".
Kahr; barrel lenght, 2.800".
Boberg; barrel lenght, 3.187".
Now to my test results, I used Win. brass, & primers. Powder was Win. 231 using 4.3 grs. Bullet was 115 gr. Rainier plated RN. OAL 1.130"
(Note: I had to shoot the XR9-S loading rounds 1 at a time, as I have had plated bullets come apart, this was to avoid that problem.)
Kahr PM9
1). 909 fps.
2). 886 fps.
3). 916 fps.
4). 903 fps.
5). 887 fps.
6). 902 fps.
7). 914 fps.
8). 927 fps.
9). 869 fps.
10). 903 fps.
Average; 901.6 fps.
Boberg XR9-S
1). 944 fps.
2). 968 fps.
3). 954 fps.
4). 971 fps.
5). 995 fps.
6). 918 fps.
7). 969 fps.
8). 919 fps.
9). 965 fps.
10). 935 fps.
Average; 953.8 fps.
Difference of 52.2 fps.
Note; I did check the average throwing out the high/low readings but it didn't make much difference. (902.5 fps. for the PM9 & 953.1 for XR9-S)
These were my results, yours may vary. LM
