I've owned this Walther 'Colt Government' model 1911 for a few years now. I'm very glad I bought it as I've had a lot of fun plinking with it. It's not anything fancy but it's a full size 1911 that comes with one 12 round magazine. I bought another mag for it after about one week.
As far as it being reliable I have no complaints. I've had two failures to fully extract in all the time I've had it. At least 1000 rounds through it. I use whatever is cheapest too. No high end ammo, just the bulk pack stuff.
The sights are okay but the front sight is hard to see because it's black. A dab of white or orange paint fixes that. Also the trigger is a little too heavy. But, for what it is it's fine enough. I think it's lightened up a smidge but not much.
Break down of the gun required me to read the instructions but it's nothing hard. I clean the pistol after every outing with it. 22lr is dirty stuff.
Very pleased with this gun, it was an impulse buy to be honest. I always disliked the 'fake' 1911 22's mostly because a lot of them are scaled down. Not this one, it like the real deal. I was at the gun store to purchase a Ruger SR22 and saw this Colt Government model. After handling both the guns I had to have it. The Ruger is a fine weapon but small and seemed like a toy compared to the 'Colt'. Never regreted buying the 1911 in 22lr. You'd never know it's a 22 unless you really looked at the muzzle. A fun gun that doesn't cost much to operate. I love it.
