the 22 mag was made in 3 lengths, I had a couple the short one, 4 in I think ,and the middle size. Never found a long slide like this one.
You have a small fortune just in the mags .
Ammo feed is really the only problem, one was real fuzzy, other one a bit better, hot hard point ammo is the best, Fed was not great, but it has been a few years now.
If I remember, the triggers are not great on them.
Last one I sold was $1k, that was 12-6
Never has the 44.
