Dear Henny
Thats only part of the story,all sights are possible on HPS-guns
Its only customer-choice,and I agree with the opinion that in time
all parts go kaputt.
This year ill be shooting the OKO,because I like the battery it uses,
I like the alu mount,I like that it closer to the slide than a c-more,
I don't like the spare sight its like they are not sure of there product.
But thats all my opinion.
I also like the Shorty open Gun they now offer.
