To me the 442 Pro Moon Clip seems to have a better and more durable finish than I have seen on some other 442's.
I am way more impressed with it's finish than the 638 I had infront of it.
Ammo & Moon Clips in the 38 Special. The Undercut at the rim is not a standard size on 38 Special Brass. The TK Clips, which are the same ones that come with the 442 Pro Moon Clip from the factory fit several brands of ammo.
They main one they do not fit is Winchester.
I have Speer 135 Short Barrel and 125 MagTechs loaded in my clips at the moment. Remington Golden Sabers will also work fine, as will Federal Hydra Shocks.
I can live without Winchester PDXl, which is about the only desirable Carry Ammo that will not work in the Moon Clips.
Moon Clips & HillBilly Carry: That is what I call Low Threat Carry in a Rural Environment. I live in a rural area, and I am not real worried about being Mugged, Car Jacked, etc in my everyday travels. I might however pop a Copperhead about anytime during the Summer months. Unless I am going to a bigger town or city, I will likely have a shotshell or two up front during the Summer. With HillBilly Carry I have a tendency to have loose rounds in the gun, so I can swap out a shotshell or two after firing them. I will probably have a Self Defense Loaded moon clip or two on the belt, but I will also have a Tuff Products Quick Strip in the pocket with a few shotshells, and normally a few lead reloads to top off the gun.
It is unhandy in this mode to carry a moon clip load in the gun.
Moon Clips & Defensive Carry: Carrying a Moon Clipped Payload in the revolver for self defense you will more than likely shoot the gun empty before reloading. The moon clips in the gun keep all 5 rounds together during ejection. The J Frame has a short ejector stroke, and is not noted for positive ejection unless you do everything right, which you may not under stress. You can grab the 5 rounds in a cluster and get them all out of the gun if you need to during a tactical reload. I can normally do a faster reload with a moon clip than I can a Safariland Comp I or HKS speedloader. Between the more positive ejection, and faster reload, the moon clip gun has a big edge in a gun fight if it goes past 5 shots.
The 442 Pro Moon Clip will work just like every other J Frame 38 as far as using Speed Loaders, and Loose Rounds. The Moon Clip Cylinder Cut just gives you another Option.
Pocket Carry of Moon Clips: If the ammunition fits in the clips pretty well (Not Real Loose) you can probably get away with loose carry in an empty, loose pocket.
I believe TK sells a Pocket Moon Clip Carrier. It fits around the nose area of the ammunition, and keeps all 5 rounds in the clip. They are a little salty, however they are probably a one time purchase also. My best guess is getting the carrier off the moon clip reload will add about 1 second to the reload time.
The California Competoition Works 5 Shot Moon Clip Carriers is the best thing to happen for a moon clip J Frame, or an SP101 in 9mm. I had a 9mm SP101 several years ago, and got rid of it because it was a pain to keep my rounds in the clips when pocket carrying them. The Moon Clip Carrier would have totally taken care of that problem, as would the Pocket Carrier.
I hope I have answered a few more questions. I am a long time user of moon clips, and I really like them.
