Yep, it only takes a range session to refresh the reason of why a 3913 is such a great single stack compact.
I've been carrying my original 3913 recently, after finally getting around to cleaning it from my last range session.
I installed the optional spring-loaded decock-only assembly in mine. For some mysterious reason my slide came machined for it, back when it was a new option only being offered to LE and the machining was only done at the Performance Center. When I called to order the decock-only assembly, nobody with whom I spoke on the phone could explain why my slide had had the machining done. Best guess I was given was maybe the PC had modified the slide for a special order or some project, but then it was canceled and the machined slide was sent back over to Production and just ended up in the 3913 I ordered.
I've gone through some different sights on mine, including the discontinued Novak Ghost rear sight, but the factory (Trijicon) nights I last installed are old enough to have finally gone completely dark. Before my last range session I dabbed some bright neon orange nail polish in round circle making up the front night sight, and it really helped the front sight to stand out to my senior citizen eyes. Similar to the way the big orange front ring of the Ameriglo Agent Pro NS catches my eyes on my G27.
While I have a couple other holsters for my 3913, I still prefer my old Hume H726 semi-open breakfront belt scabbard. I used it for my issued 6906's, as well my 3913, CS9 and 4040PD. (I have models of the holster for my 4013TSW, 4513TSW, 3913TSW (railed, late production), CS45 and a couple other brands of guns.
I've used that first 3913 for enough years on our range for me to have replaced the recoil spring a few times, and I forget how many magazine springs. Our previous duty ammunition has included assorted 147gr standard pressure loads, as well as a couple 124gr +P loads and the W-W 127gr +P+ RA9SXTP and RA9TA (different vintages). I replaced the recoil spring more often when using the +P and +P+ loads.
While I have Hogue rubber grip stocks on my 3913 (at present), I still run the factory grip on the 3913TSW. No particular reason, and both types of grips have their pro's & con's.
Matter of fact, today I'm going to belt on that original Hume leather scabbard and carry my 3913, loaded with 127gr +P+, as I go out for the afternoon.
One of the best 9's S&W ever produced, and among the all-time best compact, metal-framed defensive single stacks ever made. In my opinion, anyway.
