Not meaning to be negative but if you are looking at something less expensive to shoot why go with a 22mag over a 22lr, I mean 50 rounds of mag for 10-12 bucks vs bulk pack 325 pack (or 500 depending on brand) for appx 20 you can get alot more shootin' in with the LR. Now to have a 22mag for groundhogs, ect I understand but for a plinking handgun I would go with the LR. Just my 2 cents. I have a Mark II and it's a great shooting gun, haven't shot any Mark III's so can't comment on them.
