Looking at buying my first pistol, have questions.

[Xride]

Hi all.
I'm looking at picking up a pistol here, been looking at a new STI STInger or TruBor.

First I dont really know the difference between these two guns though.

I will be using this for IPSC competitions. and jsut general target.

My main question is what kind of maintience and costs would I have while owning this pistol?
and is there a different one I should be looking at as well?



Thanks in advance.
