I have one.
It is well made if you consider an alloy gun well made.
The pistol is full size & many of the frame parts will interchange with regular 1911 pistols.
That means you can change grips, triggers, hammers & springs, but the pistol remains a dedicated 22LR pistol.
The recoil spring is very light, & there is a recoil buffer inside.
With the magazine installed, the slide returns to battery in a sluggish manner. But, as long as you use HV 22LR, the pistol functions as designed.
I just wish it would function with subsonic 22LR.
It is a good plinking gun, & 22LR costs less than 45 auto, so it is useful for practice in lieu of the full power 45 auto 1911 pistols.
