One thing I have discovered shooting my carry snubs in matches. A steel gun is way more fun to shoot.
You will also take a lot better look at grips.
I put some nice S&W grips on my 315 Night Guard, which is a K Frame Airweight Snub. About like a souped up Model 12.
Shooting a 50 round match I am sure with one more cylinder full I would have been bleeding. When I got home the rubber grips went back on it.
My 2 Inch Model 15 is way more fun to shoot than the 315NG.
I am sure a 640 would be more fun to shoot than a 442. Light weight is nice for carry, but NOT so nice for shooting.
My most carried revolver would be my 3 Inch 66-2. I belt carry in a pancake about 95% of the time. Carrying on the belt I can put up with a steel snub revolver. For pocket carry steel is a little hard to put up with for me however. That is the main reason my 442 Pro has not been traded for a 640 Pro.
In my opinion if everyone who carries concealed shot their carry revolver in matches regularly, you would see a lot more Model 36's, 49's, 60's, 640's, and 649's carried, along with a huge increase in Snub Model 10's, 13's, 19's, 64's, 65's and 66's being carried a lot more. I am 100% sure you would see a huge increase in steel being carried if more who carried really put rounds through their equipment.
It would be nice if IDPA would make a Division for Snub's to encourage more to shoot their carry guns. The only down side for us S&W fans is you might see more shooters go to a Baby Glock instead of a steel revolver. When I get my tail kicked in Snub Division it is never by a revolver, it is always a Toy Glock.
Just my 2 Cents.
