I'm a little jaded when it comes to clones but I would have to say neither of your choices !
Hear me out...
In the history of clones they have been plagued with problems... some small problems, some huge problems.
AR15 clones have had problems too... but if I were going for a .223 home defense pistol it would be a Bushmaster type 21S or 97S.
As for a 9mm.. I have no real input. While the clones are getting better and more reliable, they are still not reliable enough to stake your life on.
I'm just saying that you want something to go boom everytime without any doubt. If you read through these threads and other boards you will find that Most clones either have had FTE,FTF or they wont feed certain types of ammo. While other guns are the same... I'd much rather put my life in the hands of a gun that has been more proven than HK clones.
I'm having an MP5 clone built, so I am not biased, but I certainly do not plan on making it my defense gun.
I have a Glock 20 and an AR for that.... anybody that walks through my door is fucked !
If you are Hell Bent on getting a clone for defense I guess I would tell you to go with the Vector 53 pistol and make Jesus Christ your personal saviour....
I'd still highly advise against any HK clone when you are trying to protect your life or your loved ones. HK clones are for fun... If you want protection by a shotgun with 00 buckshot or a high capacity Glock,HK or Sig handgun in a large caliber.
Just my 2cents though
Good luck.
