Last speedloader I bought 30+ years ago was an HKS. Is that still the one to get? Model 10-A for a S&W 64.
+1 on HKS. Mine too are >30yrs old, simple reliable and if the OP is used to HKS, stick with that style. Practice and muscle memory will make them easier to use under stress.No , HKS , because it actually is easier to use under stress , and more reliable generally .
