Well, thats good to know about your shooters, congrates to them.

I too have scored quite well with glock though I personally don't
like the gun, especially after all the exchange communication with
Johnston. 
So far there hasn't been much complain about it but I
personally don't like the design for the mag
release. It can be quite a hassle in a stressful situation & if
you're wearing gloves. Other then that, theres the weight factor.

I m not referring it to any girlie comment between me &
johnston, but seriously, the weapon is so light that I sometimes
forget that I'm carrying it which can be quite a problem, though it
hasn't occur yet. Thats why I try to carry a slightly heavier gun.
It may be incovenience but at least I know its there. 
The Walther P99 is not a very popular gun even though its been
around for a few years already but I like it. However, its not a
gun for concealment especially if you've a small body frame like
mine. Its noticeable even with wearing a coverall. 
With all thats said & done, a hand gun is much better as a
secondary weapon. Preferrable to carrry an assault rifle as primary
weapon is always better. My view is that if you've got to use your
secondary weapon after your primary, then you're definately in a
deep shit situation.
