Firefly;

Welcome to the forum and IMHO you have come to the place with lots of knowledge and experience.

I suppose you know that the Davis firearms are not necessarily known as quality nor are they expensive. In fact my friend I don't think many would place their fate in those firearms. However if that is all you have then you must make the best of it and hope all works out for you.
First and foremost learn all that yo can about awareness and being vigil so as to avoid ever having to use a firearm to defend yourself.
That is of course excellent info for all of us as the use of a gun is a last resort and bacically an indication of having failed your best defense which is avoidance.

As for your gun and its' ability to handle the ammo you mentioned, I am sure it will handle the hollow point, even in the +P category. However I would not recommend the use of +P ammo for a regular diet as it will shake the gun loose very quickly.

So in answer, practice with quality 90 grain FMJ and load the HP, +P ammo for defense only. I might even suggest you get some of the Federal HydraShok ammo for your defense loads and stay away from the +P altogether.
The Federal ammo should be all you need for self defense and should feed in the gun and not cause any undue problems in the process.

I hope this helps a little.
