Ill trade ya a equal amount/weight of lead sinkers for it
Well im sure its not equal to a ppk or is it a target gun - but its probbly more handy& pocketable the a 10 foot long sharp stick.
I have a jennings22. that cost about the same& have stuck it in my pocket etc many times on the way out the door.Dont have or doubt i ever will a ppk- so without the cheap 22 at those times i would have had nothing but a empty pocket with me.
Just fire it a bit, see if it functions ok etc.(maybe a upgrade on its fireing pin? as i heard thats a possible problem in such guns, dont know if its true or not) if your life depends on it?
$45.00 wont even buy many ppl a full tank of gas nowadays- your pistol should last a longer then that gas will.(unless you use it as a sinker

)
