The Ruger Mark II/III/IV semi-autos (and the 22/45 variants) are okay to shoot but a real nuisance to detail strip.
B.S. If you're not smart enough to figure how to quickly strip and reassemble a MK you probably don't have any business being around guns.
I'm a revolver guy hands down. So much so that I've sold off any/all my centerfire semi's. Being said, the MK series are the better guns. Easier to clean, very reliable, easier to load, more accurate, etc.
But Ruger .22lr wheelguns are very well made, accurate enough for about chore, handle well and will do one thing better than the MK, shoot a varity of ammo.
Either gun will out last you and your kids with minimal maintainence.
