Hey Johnny, I have used both Safariland and Seidler Jetloaders, and in my opinion I have found the Seildler to be far superior. I have used and still have a couple of Safariland Comp II's but find that they hang up sometimes, especially when they are used a lot, as I said, my opinion only. I do know people who are as passionate. I have bought most of mine through Brownells when our dollar was good, I will just wait a little while longer for it to get back up there.
as for the speed loader pouches, I use a Safariland and I am quite happy with them, there may be more on the market over in the US. It's just a matter of asking enough people.
Holsters are ones own preference, talk to people and see what they use, pretty much personal preference. I bought a double alpha for my model 14. I have used a lot of holsters over the years and this was my first venture into a "ghost" type holster, glad I did it is probably the best holster I have ever bought. I was a bit wary of it holding the gun in, but boy is it quick and no worries about security. I bought mine from Double alpha, but I see there is a link for US. Mine, with both inner and outer belts cost me less from Double alpha than it would have here in AUS.
