I like their 1/3 (2-round) moon clips.
Load & unload by hand, & they seem pretty durable.
My old commercial 1917 has been reamed for 45 Colt by a previous owner, so moonclips are a must for me to shoot rimless cartridges.
But I do have the additional option of shooting 45 colt.
So I've got that going for me (in my best imitation of Bill Murray as Carl the groundskeeper voice)...
