I like my 22/45 it has been very durable and I have shot the poop out of it. Mags are cheap, $10 to $14 each. They can be challenging to take appart and reassemble. It is very accurate event with cheep federal 550 round bricks of amo. Some of the 1911 conversion kits demand more expensive high velocety amo and will not work well with the cheap stuff.
On the negative side after 40,000 rounds the ejector pin loosened up causing all kinds of malfunctions. (I still have to fix that.) The triger pivots instead of pulling strait back like a 1911. The mag angle is different than the 1911 so reloads won't be the same. All and all a good piece of equipment for a small price. I would buy another for sure. It's a great gun to learn how to shoot with.
Just my $.02
