Welcome to the shopping for a new HK host gun and I am assuming a sear or trigger pack to go with it. Should be an interesting discussion and if you were near Indiana, would say when do you wish to go shoot a few MP5K's, MP5s and of course a HK53s (IMO a must have HK host gun ... along with something having a belt ;-) as most everyone in the group has all four (i.e. MP5K-PDW, MP5A2/A3, "HK"53 and MM23e). However, looks like too long a drive to SC and no shoot at KCR this spring, thus the best I can offer is a few postings, exchange of PMs and/or e-mails or phone calls.
Have an initial question - have you fired a MP5K along side a MP5? The MP5K is "cooler" but the MP5 is a little slower rate of fire, little easier to make run 101% and better for sub gun matches. My son's favorite of the two is the MP5K (but still behind the Thompson ;-).
The first discussion points are to focus on what are you looking for:
- Are you after a nice shooter or looking for a near as possible factory correct MP5K for collecting that will never see much time out of the safe?
- There are not that many transferable push pin MP5K's around, appears to be a lot less than push pin MP5s. Anyone have a nominal number or just sound off if you have seen one ;-).
- If you are a shooter, would recommend getting a sear or consider one of the remaining (if any) converted trigger packs from Doug (Shattered can give you contact information).
- Do you wish to own a MP5K (pistol length with no three lug muzzle) or a MP5K-PDW or just a MP5K size gun for shooting full auto (i.e. modern 3rd party stocks and optics allowed)?
- The MP5K is the smallest (by an inch or two ;-), fits in an un-modified brief case and can have a stock added for better off hand fire (vs using the sling/holster in tension).
- A basic shooter grade gun would be a HK SP89 with sear in a sear pack (note I prefer a SEF pack over a burst pack), K trigger housing, selector, stock and K grip plus possible a paddle mag release.
- Next upgrade is a 3 lug barrel, which you have options: Factory MP5K-PDW for over a grand now day plus installing, HK94 barrel shortened and adapter installed, CHs added three lug and RCM barrels.
- Do you wish to have the gun remarked from SP89 to MP5KN (or what ever is correct ... myself being a shooter my SP89 still says SP89 until is visits Terry or Mike one of these days)?
- If you are going with a factory barrel and having the gun remarked, might be easiest to find an already converted gun with these features.
