Anyone have any experience with these clones ? I'm hearing the are made on HK machines and tooling. Indications are that HK also provided them with specs and factory tecs to produce the roller lock platform. I'm on the fence as to whether pick one up or go with the SP5K. I can get the MKE Z5RS for $1510 OTD, where the SP5K is about $2200. I'm also not happy about the HK not having the paddle or being suppressor ready. Thoughts?
