HK P30sk Da/sa with optic cut from and trigger work by Langdon tactical. 10 lb hammer spring, grey guns short reset system, grey guns flat trigger. 

holosun 507c ACSS Vulcan red dot can be included for $200

I've probably fired a couple hundred rounds through this and it has been very reliable. Selling because I like the HK LEM trigger system better personally.

interested in other HK pistols potentially for trade.
