I had a solid rib version and regrettably sold it some years back.

Smooth operating,very light weight,nice handling. The lineage to the Ithaca 37 is obvious.

Seems to me that the Remington 17 has a positive trigger disconnect, and does not have the so-called 'slam-fire feature' (a misnomer but that seems to be the way most people know what you're talking about).

Never had any problems with mine and I shot it a lot.
Never can't recall anyone asking for repairs on one either.
I'd guess that parts would be difficult to come by if you did need to find some and most any around will be well worn bits from stripped down parts pile guns.
That's just the way it is with old and especially low production guns.
