I'm ashamed to admit that it's been almost 2 months since I last shot my new CS9, and I've only shot my 3913 twice in that time ... My only excuse is that I've been shooting the issued 6906 for a couple of thousand rounds ...
I had to do my "recorded" quarterly qualification with current duty & off duty weapons last week, which meant I had to drag 7 different pistols and a snubnose in ... which is actually less, believe it or not, than I've listed in the past ...
Anyhow, the off duty pistols included the 3913 & CS9. I used a mixture of a lot of 124gr +P, 115gr +P+, 127gr +P+ and 147gr ammunition through both pistols. The distances in the current qualification courses only run from 7 to 11 yards, but they all include "precision" targets at all distances, comprised of small "bullseyes", and head shots on silhouettes, in addition to the usual COM targets ... movement, barricade shooting, etc ... We had a lot of 3-5 yard targets during the previous couple of quarters, but wanted to bring some emphasis back on accurate, "precision" shots this time around ... I know some shooters will question any target closer than 25-50 yards being called a "precision" shot
but when you include short time limits, and other factors, it can be challenging to the "average" L/E shooter. It's all relative ...
Even though I have the "open" Novak Ghost Ring rear sights on these small pistols, they were more than accurate enough to equal the duty pistols regarding accuracy, and they digested all of the +P & +P+ ammunition flawlessly ... again. I also used the 8-round 3913 magazines as reloads for the CS9.
After running through the regular "duty" course with the off duty pistols, I then moved up to shorter distance (1-5 yard) close combat scenarios, with single and multiple targets ... and then used the reduced sized pepper poppers out at 15-25 yards. These little pistols always amaze me with their balance, handling and shooting qualities.
If you want a small, aluminum/stainless steel, single column magazine DA/SA pistol, the current S&W offerings may be just what you're looking for ...
