OK! I talked with a national Police and Bullseye champion and got his advice on the speedloaders. Safariland Comp III seems to be the top choice, as far as top level matches are comcerned. I also got some very good info on some additional tuning that I can do to my two new revolvers.
I've got 4 Safariland CompIIs from '92 that are just fine today. you hear about rotating ammo and speedloaders but it's all about care, storage and inspection. I had two on the range a couple weeks ago and they are fine. My HKS's are good also but I've always liked the push and release style. Just keep them clean.
