BaaBaa I was refering to kydex carriers. You are no doubt carrying the Comp I's in a nylon belt pouch, which is OK, just normally a little slower to use.
With pocket carry a vest with pockets is normally used, instead of pants pockets.
The HKS requires you to hold the cylinder, so it does not spin when you turn the knob.
The Comp I and Jet Loaders work similar. The difference is that the Comp I just releases the cartridges. The Jet Loader is spring powered and pushes the cartridges in the chambers. The Jet Loader has more to hold onto also.
This is what a Jet Loader looks like in a Big Creek Carrier. The knob sticks out the top, making a good handle to pull the speed loader out of the carrier. It also makes a good handle to position the speed loader over the cylinder for a quick reload.
Keep having a good time. IDPA Matches are a good training tool if you shoot them tactically, and do not concern yourself with winning.
You are doing several things right. You are using the Speed Strips for Load and Make Ready. I would venture a guess that most folks who carry a reload in a speed strip never practice reloading with them. Load and make ready is practicing reloading with a speed strip.
(Info: A Tuff Products 7 shot speed strip gives you something to hang on to when reloading a 5 shot J Frame)
The next thing, I would guess the 640 is either your House Gun, Concealed Carry Gun, or both. It is a very good plan to train with what you carry.
Lots of IDPA shooters have a full size match gun, and conceal carry a pocket pistol. Not the best plan, unless you put the time in shooting it also.
Looks like you also have a practical belt carry holster.
I will be honest here. I have a 442 Pro Moon Clip. I carry it some when I want to go small. If I were to have only ONE revolver, and I were going to shoot matches with it, as well as conceal carry it. The 442 would get traded off on either a 640 or a 2" K Frame as soon as possible. The steel guns are a lot more fun to shoot.
By the way I have a couple 2" K's and a 3" 66. They are what I carry most, because they are shootable.
I shot my 315 Night Guard with S&W wood Boot Grips in our last Defensive Pistol Match (50 Rounds). The 315NG is an airweight K Frame. It is almost exactly the same weight as your 640. It would have brought blood with another couple cylinders full. I put the factory Pachmyr Compac's back on it after the match. S&W had a good reason for putting that grip on the 315NG from the factory.
Enjoy your shooting, and keep us posted on how you are doing.
