There are many good reliable guns, the P series Rugers is
one we trust fully, most of them have a manual safety, only
for you all that can remember to flip it off in time of need.
If you get a glock and you only want one gun, or two,,,
I would think about a g35, 22, 23, 31,,, NOT a 9mm.
With a Glock in the 40 or 357 sig you have many
more options if ammo gets hard to find, and it will,
also will work for things like hunting,,,
For 40.00 you can get a conversion barrel to shoot the 9mm,
all my glocks have conversion barrels to shoot 9mm,
would/do trust them for HD and or carry, you must prove
them, also must prove any new gun with new ammo.
Don't limit yourself to only one caliber, especially one
like the 9mm.
The older gun people know this from thirty years experience.
Here are some barrels we have tested, probably around twenty ,
and many others that cost much more.
Swenson Conversion Barrel Glock 22 40 S&W to 9mm Luger 1 16 Twist SS
Swenson Conversion Barrel Glock 23 40 S&W to 9mm Luger 1 16 Twist SS

Once again, until you prove the conversion barrels, only use
it for low cost practic, use only the OEM 40/357 sig barrel HD.
Get with a shooter that really knows something about shooting,
he will help you a lot.
You can get a good used g22 for aorund 280.00, got one
for each member in the famly, with the extra 9mm barrel.
