I had a Stoeger about 16 years ago , Brazilian mystery wood (stained) , needed some polishing , never dicked with the Spring
but did de bur ...sold it for what I paid for it so all in all good juju.
Didn't own but did smooth out a Baikel MP220 for my pard about a year ago....
Heavier than a Stoegar about in line is craftsmanship, Russian beech wood (stained)
stiff " strong like bull " needed some polishing , somehow feels more robust , overall than the Stoeger I remember.
Both utilitarian, and plain as Jane ... the Ivan is just that plain , but Stoeger does put lipstick on ( upgrade in wood and finishes )
So with Ivan you get a $300 +or - gun for $300 + or - depending on the retailer.
Stoeger you pay upwards for the lipstick .... which does add to the allusion
Both work well enough to layout the knockdowns @ cowboy distance
That said, I won't get into, oz of lead , or recoil , 2O gauge VS 12 gauge...wasn't asked
I note: spring kits are now offered for both see Palo Verde
